(groaning) (tense music) (pained groan) Brains. (screaming) Sir, you dropped your wallet. (upbeat piano tune) Brains. As adult humans, we
often have to think about the future, like our
diet and retirement. But have you stopped to
think about the possible impending zombie apocalypse? Cause we have. (laughing) So we are gonna make some
weapons out of common, everyday hardware items. Stuff you can get in a
pinch if it goes down. Cause you don't know
when it's gonna happen. (growling) (laughing) Did I get you? (vintage music) All right, so what are the
common reasons that people die in zombie movies? I think--
They get bit. But I think they--
Disemboweled. let zombies get
too close to them. Yeah.
So. I wanna like have
slightly ranged weapon. My first thought
was getting an axe, and attaching it to a pole. And I said that was lame. And you just have
like a long axe. Okay. So, so I like your idea
of having something that is slightly ranged. Yeah. But I feel like we can take
it farther and do something a little bit more creative. I want to make a flail. Made out of nails. A nail flail. (laughing) It is really clever. It's really clever. I think it's a good idea and I think it's
going to be effective. Okay. No, no the thing that sold me is like I think we've
come up with a way to make the nail flail, the flail part of it
really light weight. Cause that is one
of the challenges, you don't want too much
weight on your zombie weapon. Yeah, I mean we watched
a lot of zombie movies, we're pretty much
experts at this point. By the way what's your
favorite zombie movie? Shawn of the Dead. I'm not sure how much
we can learn from that. I mean pool cues work. (laughing) Cricket bats. Okay. Okay what was your plan,
sketch it out for us. Okay, so we're thinking
plumbing pipe for the pole that we're gonna hold onto. And then we'll weld a chain
onto the end of that somehow. And the challenge
part is the ball. My idea was just to stick
a bunch of nails together and keep adding more
nails on more nails until it just
became a giant ball. But like Evan said that
would be super heavy. And we need space in
between the spikes for it to really
like stab in there. My thought is just to get
a whole bunch of washers, weld them all together
in a ball shape. And then weld nails on to that. Try to find some foam
thing, glue the washers on, then weld it, then
put the nails on. And then melt the foam? EVAN: With fire! (upbeat music) Ow! EVAN: Oh no! My nail. EVAN: The dangers of
making zombie weapons. Weapons effective. The breaker of chains. If we're using screws does
that mean we can't call it a nail flail? There weren't any
nails large enough. I'm sorry Katelyn
your idea is screwed. KATELYN: Okay. You know. Biggest washers we could find. Did you find the pole? I'm doing pole dancing. Am I doing it right? KATELYN: Yeah I think so. Adding some special
effects later. (retro cat music) I know we said
this would be made from hardware store stuff but, we also need some
craft store stuff. Now I think I found
the perfect ball and a bonus, there's
caution, flammable. I think that that'll
be a good thing. I hope this doesn't
bite us in the butt. (crashing) Okay so we got home, we
have all of our supplies. And Evan tells me that he wants
to change the product idea in a fundamental way. So my main concern is that
when we start welding on this, even if we have everything
glued into place, this is just gonna melt. It's gonna catch on fire
even with just like the heat and sparks from the welding. So-- Just like a little bit. Ow we're gonna wrap it. I Think if we wrap this
with aluminum foil, and then we glue the washers
onto the aluminum foil, then the aluminum foil will
protect this during welding. There's a fundamental flash
here, fundamental change. Burning it out will be hard. Yeah, how do we remove the foil. (dial up tone) (interlude music) Do we need to burn it out? It'll look cool if it's hollow. I don't know the whole point. But It'll still be light weight. Yeah it'll just be
covered in foil. We'll just pretend like the
foil's an aesthetic choice. Yes, no, no, no, the whole
thing is like literally metal. It'll look solid. It'll look like
it's solid metal. It'll look like
it's solid metal. Yeah. (interlude music) Ow shit. (wasted theme) That wasn't-- (laughing) All right after much
debating we have decided-- That we're just gonna
see what happens without wrapping it in foil. Cause it'd be super
cool to burn this out from the center of our flail. I just wanna see that. I just wanna see it. And if it doesn't work, we'll figure it out then. We have enough time before
the zombie apocalypse. We have like, you know, one more shopping
trips worth of time. Yeah, yeah. Alright, Let's get our glue gun out. Okay. So I guess another question we didn't really
ask ourselves is, will the hot glue
melt the styrofoam? Yes. Will it set it on fire? No it won't, it
won't set it on fire. Okay. So I'm gonna apply it to here. Wait, wait, wait. I just had a thought. (inquisitive music) These are zinc plated. Are we going to have to grind
them before we weld them? If we glue them all down, we won't be able to... Grind it. (interlude music with static) ♪ Science adjacent with
Evan and Katelyn, yeah ♪ All right let's
back up a second. So, going back to basics. The easiest seal to weld
is just a mild seal. It's just low carbon steel. Sometimes it's hard to
get different pieces in just that mild carbon seal. So these washers for example, they have a zinc
coating on top of it. Which is like a really
thin layer of zinc and that just protects
the steel from rusting and everything like that. These guys right here,
they're galvanized steel. So they have a coating
of zinc that's on it, that's 10 times
thicker than this. You can just see
that thicker coating if you just look at it visually. So we can't weld the items
that are coated in zinc because the off gases
are really bad for you to breath in. And we don't wanna have to
grind off the coatings of however many individual
washers we have. So we did some research and there are other ways to
get rid of that zinc coating. Mainly you can
remove it chemically. (upbeat jazz music) you're tub is a disgrace. (laughing) Okay so the two
ways we looked into. One you can use vinegar and that will eventually
dissolve it off. But, the downside is it
takes around three days. The other thing you
can do is citric acid. Which sounds kind of scary because it has the
word acid in it, but it's basically like the
powder put on sour gummy bears, or like, remember war heads. Woo! My school like, everyone brought
them and like traded them like,
Ow yeah. Like prison cigarettes. Was it watermelon? Ow yeah watermelon was so good. Anyways, citric acid will
dissolve it off of the-- Metal. Will dissolve it off the
metal in about three hours. And you can get it
at the grocery store. So we're gonna try that one. (upbeat music) Got some. Yep. So on all of the
online tutorials we didn't see any measurements
of how much to do. So we are completely
making this up. We'll let you know
if this too strong, or too little. We're gonna do half
a cup into 16 ounces. Because, why not. (laughing) Gonna start dropping them in? All right. This is the satisfying part. Ow they immediately react. Look at that. See the bubbles on them? No. Look at that one. Like on that one, you see there's bubbles
developing on one side of it. Ow yeah, ow yeah I see it. (clanking washers) it's not powdering anymore. Yeah, and this is what happens. So here's the before,
here's the after. Basically it's less shiny. And that's all you can see. Yeah.
(laughing) okay so, time to attach
these to a sphere of foam. (joyful music) Should I wear safety
protection for this? Uh maybe. You know. We're wearing the same t-shirt. I mean I guess this makes sense. I wore this shirt first. No I was wearing
this shirt yesterday, so I wore the shirt first. (laughing) That's a lot of hot glue. I'm gonna put it on the washer. Because I worry if I
put it on the foam, it's gonna, melt it. Hey. That's great. There you go. What should we call it? Franky. (wind blowing) Okay well didn't melt it. It kind of feel like
doing arts and crafts, but like instead of
being fun and games, it's like-- Life and death. Yeah that. Ow wow. That's like still quite weighty. Yeah. But I can't even imagine
how heavy this would be if it was solid metal. I'm glad we're going for
this hybrid approach. Plus it looks cool. Like this. Don't pay attention to the gaps. They'll be filled in soon. That brings us to the next step. Welding and-- To make this whole process
a little bit easier we're actually going
to be welding on this little stick right here, so that we can move it around
and keep it all grounded while we weld. (funky music) It got too hot and melted off. Uh oh, I can glue it back on? Nah let's see if I
can keep on going. This video is literally made
possible by Lincoln electric, we're using their newly released
power mig 140 MP welder, plus all Lincoln gear,
Lincoln fume extractor, Lincoln everything. KATELYN: We love Lincoln not only because they
were cool with us making a zombie weapon, but also they make welding
way less intimidating. We're still pretty new
welders, but the power mig is really easy to use, and the crazy thing
is it's only $782. That's insane. EVAN: And we couldn't
think of anyone better to face the zombie
apocalypse with. (laughing) So thank you again for making
such great products Lincoln. We'll link literally everything
we're using down below in the description. KATELYN: Thank you. He protec. He attac. But most of all, he knows how to tack. That was a good one. Thank you. It's like a evil cake pop. KATELYN: Oh my god. Oh it's like squishing through. I know I think the foam
expanded, because of the heat. And then some places it started
catching fire and melting. But I think we should just
like set the rest of it on fire and burn it out. KATELYN: Yeah we should do that. Maybe not indoors. No, no, no. That looks so cool. Yes we're just gonna do it. We're gonna do it, yeah, ready. KATELYN: Yeah. (blowtorch firing) Ow yeah that's going. KATELYN: Just gonna
have a cozy fire pit. EVAN: That looks
so freaking cool. We should make a
fire pit like that. I don't know how we'd
get fire wood in there. But it looks awesome. KATELYN: You just
don't close it. You just leave the top open EVAN: Open yeah. KATELYN: Ow my god
we gotta do that. (blowtorch firing) (upbeat music) EVAN: This is going
to be so epic. KATELYN: That is
not a fire crackle, that is just so cozy. (blowtorch firing) This could be the
thumbnail right here. Ow wait, there,
there, there, there. KATELYN: Ow my god. What is happening? Now it really is a
cake pop of death. It's dripping. It's the plastic
that's inside of it. Man. KATELYN: Ow my god. Dang. Okay now to cool it off. (water splashing) Ow jeez. Next we get to add-- The spikes! A mounting point,
and then the spikes. Yes. We should probably like
firm up those tacks, because we're going to be
smashing it into things. I think that's like
some what secured, but I think we should like
go back and touch that up. And then spikes.
yeah! (sparking) (upbeat music) Check this out. Not only does this look cool, but look at what I was
able to do with the welder. I was able to close
the holes completely. Kind of for strengthening it, but also just to see if I could. I was able to like
weld those shut. KATELYN: Ow that's
so much better. That's so crazy. But also. (banging metal) Like this right here. KATELYN: That's like
a lolly pop of doom. That's already a zombie weapon. Okay, should we explain
what we're gonna be doing for the next step. Yeah, so, before we
attach the spiky bits, which I'm really excited about. We need to figure out how to
attach everything together in a way that makes sense. And key to all that is
this swivel right here. So we're gonna have swivel
points mounted to the pole and to the ball
connected by the chain. That way when we're-- ♪ Swinging the chain ♪ ♪ Swinging the chain ♪ ♪ Swinging the chain ♪ It's not like twisting up on
itself and getting tangled. So it's a similar
process to last time. We're gonna soak all the
hardware in citric acid, dissolve all the zinc. Then we're actually
gonna cut off one end, so that we have a
better mounting point. Then we shall weld
one to the pole. (sparking of welder) One to the ball of death. And then we'll have this. Huh hu! Look at that, it's beautiful. It spins without
getting tangled. ♪ Wow ♪ Let me see if I can
just do a little like (alerted ping) No, no, no, no, no,
no, no, no, okay. (clapping) Well at least the spikes
weren't on it yet. (laughing) Speaking of spikes. We probably could use
these screws as is. But we want them to
be even more deadly. Yeah, more stabby. Well also it's like,
with these ridges, if you slammed them
into something, it might get stuck there. And you need to like-- You need to retract it. You need to be highly
agile with this. So, I think it's time for
a little bit of grinding. Yes a lot of grinding. There's a lot of screws. (electronic music) This is taking too long. KATELYN: I told you that
would take a long time. And you were right. Science experiment time! All right so before we
grind the rest of these. Let's see how much of
a difference it makes between...
yeah. The fully sharpened,
halfway sharpened, and the nothing
at all sharpened. Because if one of these two, the halfway or
the nothing works, we can save a lot of time. Not having to grind
up all those threads. Yeah so I guess, let's
each do both tests, then we can get
like a feel for it. All right ready? Yeah. All right. KATELYN: That seemed
to take some force. I'm gonna do one more. With like a little bit of a-- Oh yeah.
Oh yeah. That went in easy. So you just gotta like get
some momentum behind it. Yeah. Ready? Yeah this is the half. Oh it stopped it at the threads. Try again. (squelching of watermelon) okay you can't.
It takes more force. It pulls out some guts. It breaks it, you see
how these are holes? KATELYN: Yeah. This is like more of
a shattering force, then a stab force. Feel like it might just
knock the watermelon off, honestly like this isn't
going to do anything. (laughing) Yep. Look at the size
of that hole too. It makes a huge difference. I feel like you have
experience this too. I'm just curious. (laughing) yeah. Juicy. Try the worst one just
as like a comparison. You just wanna laugh at me? No I just wanna see more data. More data is needed. I actually like did okay.
Hey. You did okay. I had a feeling that it
was gonna be like this. Yeah me too. (laughing) Well we have several hours
of grinding ahead of us. So shall we slice up a snack
and then go into montage mode. Montage mode. (electronic music) (screws grinding) (elevator music) (electronic music) (screws grinding) Steamy! Woo! Woo! Are these too big? (inquisitive music) If they're shorter like this, they do a lot of damage. They'd be easier to pull out. Because they're so long
it's gonna get stuck more. What are you proposing? (electronic music) This is the part I'm
very excited about. We're gonna weld on the spikes and complete our weapon. EVAN: Is that supposed to
be like a dramatic scene? Yeah, but my hand was already
like kinda far in it so... EVAN: Do it again, do it again. (electronic music) Welder on. Fume extractor, on. How am I going to hold
these tiny spikes? EVAN: Carefully. (welder sparking) That's looking so cool. Yeah. Woo! Oh my gosh. Look at it. Look at what we have created. So wicked looking. (Evan laughs) Are you ready? EVAN: Time to smash
things with our... Flail. Are you ready to
destroy some zombies? EVAN: Yes I am. (dark electronic music) Hopefully I don't miss. Count me, count me
out, okay, wait. Let's not swing it when the
other person's not ready yet. I'm just getting my swing right. Three, two, one. (flail crashes) Oh yes! KATELYN: Oh my gosh, whoa! (laughing) It's super effective. It's super effective,
I'm wanna do one more. Oh, Katelyn look at this. Look at that. Ow my god. Oh my god. I know. I'm not sure if the
table's gonna survive this. (laughing) (Katelyn and Evan) ow! Direct hit. Oh my god. Yeah! Ow my god. Oh my god that was brutal. That was brutal.
Oh man. EVAN: That was an explosion. KATELYN: The carnage. That was such a good hit. Jeez. Katelyn you got to try this. You got to try this. Choose your enemy. Yeah! (electronic music) I'm a little nervous about
like being able to swing it with enough power, you know. EVAN: Better to err on the
side of caution and safety, then power and destruction. You can always get
a second chance. Yeah. (tense music) Okay. So let's see, how
close do I need to-- I probably need to
be about this close. I wanna hit him with the ball. All right watch this. Let's be careful about this. Pull back. Okay, so we have my stance. (Evan laughs) Give me a count down. Okay. Three, two, one. (discovered tone) (Evan laughs) I saw that coming. Practice, I was scared
to hit the table, I aimed high. Okay. Now I'm nervous. Two, one. (flail crashes) Well... (comical music) You know acorn squash zombies
are immune to side swings. Don't mock me with it. (Evan roars) okay, okay let me
try it over hand. Okay, okay. I'll try it. It's a much harder, like, food item to smash. You know the watermelons
are the easiest. I should have taken the banana. (Evan laughs) And you just like let
it slam into the table? Yeah. (flail crashes) Alright see it was barely a hit. Look at all the-- wait, this is so
good, this is good, like everything like flying. I have to redeem myself, I don't want to like the
squash to go on forever. (Evan laughs) ♪ Here, far, my
squash will go on ♪ Is that how the song goes? Yeah. (Evan laughs) This looks like a good position? (happy music) I don't know. Come on I had to have hit him. It was close again. Okay you know what
he's final boss, I'm gonna pick an easier one, and we'll come back to him. EVAN: Okay. I need a win.
(Evan laughs) (electronic music) Who's next? Frigging bananas. (Evan laughs) EVAN: Frigging banana's man. Frigging banana's. Three, two, one. (flail crashes) Yeah! Yeah! Yeah! (roaring) Got them! See I can swing it. It's just squash man. (Evan laughs) EVAN: So let's look
at the slow-mo. KATELYN: Yeah. EVAN: Ow yeah! You did get him. KATELYN: I got him good. [Evan] They're all separated. Ow my gosh. Choose your zombie. Melon. He's getting away. One. (Together) Ow! EVAN: Yeah. KATELYN: Right in the brain. (murmuring) EVAN: In the air, yes. [Katelyn] Ow my gosh. This is a good weapon. This is very effective. The bolts holding
up really well. It's not deformed, we're not missing any spikes. Wanna do like the soda. Yeah. You only really get one
chance with the soda. If you graze it, you
don't get a good hit. EVAN: That's that. You don't get the explosion, you don't get to try that again. I may or may not
regret this later. Are you making him angry? Three, two, one. (flail crashes) At least you didn't graze it. (jolly music) I hit it. You hit it? Look at the slow-mo. Okay I didn't hit it. (Evan sniggering) Okay I hit it, but like I
didn't hit with the spike part. Okay, one more time. Yeah, yeah. Going down. (tense music) two, one, (explosion) Whoa!
Whoa! It sounded like a gun shot. I'm infected. Oh my god, oh my god. Look at the slow-mo. I really feel like an
episode of slow-mo guys here. (Together) Yeah! EVAN: Ahhhhh! KATELYN: So good. EVAN: Oh it's so gory. KATELYN: Oh everything's
covered in big red now. EVAN: Oh my gosh those drops. Ow it looks so gory. KATELYN: It's like
raining blood soda. It just keeps going. It just keeps going. EVAN: There's so much. ♪ It's raining red, hallelujah ♪ I like how you can
still see his face. I'm defeated. I'm gonna get
lettuce real quick. Before it's time for final boss. Okay mister cabbage, we're on to you and
your cabbagey games. It's like plants verse
zombies but opposite, where the plants
are the zombies. KATELYN: Yeah. And we're the farmers. Okay you ready? Ready. Two, one. (flail crashes) Woo! Woo he chopped. That's some coleslaw. Gonna make some salad. KATELYN: I like how
we had the same joke. Okay slow-mo. EVAN: Right in the head.
KATELYN: In the face. Look at him go. Look at him flying,
EVAN: It's beautiful. KATELYN: his wings are spread. His guts are leaving his body. Ow majestic. Katelyn your arch-nemesis
has reappeared. To taunt you. KATELYN: I'm ready for you. Yes, lay down. (Evan laughs) Are you ready? EVAN: How can one be ready
for such a momentous battle? Three, two, one. (flail crashes) Did I do anything? EVAN: No. It did gouge him. Maybe he is like
the toughest one. He's the toughest, I
told you about squash. Okay I will not overshoot. I will hit the squash. Do it again, just do it
again, just do it again. Too far. KATELYN: Dang it okay,
he's going in the back. EVAN: It's always too far. Too far again. He's also just really tough. EVAN: You missed. (Evan laughs) I mean, he's really tough. (flails crashes) I hit him. EVAN: You hit him dead on. He is tough. Look he bounced, he bounced. (dial up tone) Do you wanna try? EVAN: He just shrugged it off. Okay.
KATELYN: Wanna try it? I'll try it. I'll give it like my
full strength attack. Avenge me. All right. You have softened him up
for me though, look at that. Lots of gouges. KATELYN: Yeah. Lots of damage done. KATELYN: Yeah. I mean he's probably
at 50% heath right now. KATELYN: Definitely. Make sure to put
your face mask down. Okay count me down. Three, two, one. (flail crashes) (Together) Ohhh! How do you like us now? How do you like us now? (joyous music) Katelyn look at this-- I went a little bit too extra. KATELYN: Oh my god, oh my god. I think it's time for the
end of life for this table. KATELYN: Yeah. It needs to go out
in a blaze of guts... and gore!
KATELYN: Yeah do it. Yeah. and destruction. Yeah dessstrucction. Chaos. Debauchery. Debauchery. Debauchery. Debauchery. Debauchery. Three, two, one. Yeah! Yeah. (triumphant music) KATELYN: We have
defeated the horde. (Evan roars, laughs) He, he, he, He,
he, he, I got you. (high five) Well, I feel like we've
proven that you can make a pretty darn good
zombie apocalypse weapon from stuff at the
hardware store. Heck yeah. Katelyn did you here
that, more zombies, let's get 'em, let's get 'em. Run, run. P.s. we filmed an entire
behind the scenes video of Evan doing my zombie
makeup for this video. It's on the second channel, bye. (Evan laughs) Turn right, turn
right, turn right. We're good. Act natural.
normal. Hear that sound... It's the sound of your
brethren's juice dripping. Are you ready?
That zombie makeup was really good! Evan should start another channel dedicated to that.
From a safety standpoint, swinging a heavy metal ball with spikes around 3 feet from their gas meter was probably not a good idea. Interesting design though.
Came for sharp spikes. Got chain. :(
