Molten Metal Squirtgun!

hey guys it's Kevin the backyard scientist and recently I've been noticing that a lot of people have been making some crazy squirt guns and stuff so we've got grant Thompson and Mark Rober both made some crazy water guns and I thought it's time for me to enter the fight so I made something pretty cool here hold on I so these are not your average squirt guns these squirt guns shoot molten metal and this was the first film I made I made it about a year ago and it's pretty crude in design so it's got a plastic air tank it's got plastic hoses on it and the reason I had to make a new one is because the cylinder is totally breasted I can't refill it so I made this beast this is my new multi metal squirt gun and it's made out of pretty much all stainless steel stainless steel owes as high-pressure fittings everything works really great it's super simple and design basically just uses compressed air to blow down into the hole here you can see there's two pipes here and it blows compressed air through here this is full of molten metal it forces the molten metal out of this tube into a nice cool stream hopefully well I need to keep this airtight so I need to use teflon tape on the pipe threads here but the problem with that is teflon melts your decomposes at like 400 to 500 degrees Fahrenheit so that limits the metals that I can use in the molten metal squirt gun so we are going to be using pewter today so I went over to Goodwill and I got this this vintage priceless pewter and just we're gonna just melt it down here yeah that's nice and we're gonna melt it down and then take some of this pewter and pour it into a mold and this is what we'll be using to fill the gun with let's get started now it's time to melt the pewter and it's easy to do because it has a low melting point of like 400 degrees Fahrenheit don't quote me on that but it's easy to do with this garden weed burner so I'm gonna turn it on and set up the cameras okay now it's all melted and this is the tricky part okay everything set everything's ready to go it's hot I'm gonna wear this gas mask because I don't want you to breathe molten metal vapours in the air and set up the camera set up the camera let's get started okay here we go connected the compressed air turn the compressed air on all right bolt the metal done three that was just like a smart gun it was perfect I forgot the truth of the camera well I forgot to trigger the camera I was so excited are you guys brought you here we go awesome I think I got it I want to see what the stream of molten metal looks like coming right at the camera but I don't want to shoot it at my camera so I'm gonna put a piece of glass right here in between the camera here we go molten metal versus glass in 3 2 1 okay let's check out the damage here I'm surprised that it didn't break their glass I thought for sure that the glass would have broken either from the heat or from the you know the force of the metal hitting the glass but let's see if I can peel this all off at once oh yeah that's nice so this is pretty cool the whole thing just peeled right off and it's full of these molten pewter stalagtites on there yeah stalactites cuz it's like that and it's pewter it's so it's so it's a really soft metal so I can just bend it like this and then we can melt it down and reuse it again alright for our next test we're going to be destroying this nice expensive pewter pitcher so we'll see if we can cut through it with the molten metal they're made onto the same metal so it should work let's try it oh yeah baby let's go take a look at the damage over here so right here this is the entry wound and then this is the exit wound the whole back of it was blasted out it's still a little bit hot but I let it cool down for about five minutes because I didn't want to be around all that dust this wasn't even fair this was like a hot knife right through butter didn't stand a chance and look at how far the look at how far the spray went there's spray on the driveway all the way all the way over to there pretty much see little bits of pewter over here oh guess I don't know how I'm gonna clean any of this off and look at this it's even on the palm tree down here everything is completely covered in molten pewter basically even on here there's spray this gun is bananas or should I say it's watermelons let's do the next test now I'm gonna try to shoot this watermelon and I don't think anything that crazy is gonna happen but you can't have a backyard scientist video without shooting a watermelon of something so [Music] oh yeah I didn't do a whole lot to that watermelon alright this is gonna be the last shot with pewter cuz it's all the pewter I have left I want to shoot it into the fish tank and see what happens when it hits the water so here we go I [Applause] put these paper towels in the bottom of the fish tank because I thought that there might be a pool of molten metal and it would like crack the bottom of the fish tank but that didn't happen at all I mean it just exploded when it hit the water there's no solid pieces in here at all it just turned into popcorn I really just exploded just because we're out of pewter doesn't mean that the fun has to stop in fact it's just starting because you can shoot any liquid out of this gun and I mean any liquid so we're gonna be making some hot dogs but hot dogs aren't in liquid so we're just going to be shooting ketchup and mustard at them so what we're gonna do is just fill it halfway with ketchup and halfway with mustard then we can do all the hot dogs at the same time there's the mustard oh my gosh this is disgusting the plan is to get the ketchup on to haul two hot dogs before the mustard starts coming out and this could also run off of the built-in air tank so I didn't need the compressor hooked up to it alright here we go this is ridiculous ketchup here we go there we go there we go oh here's the mustard oh my god that went so fast that went so fast I didn't even have time this is a travesty these hotdogs have no ketchup on them I don't care I like mustard alright now let's try some cheese wait a minute that wasn't cheese when I said this gun could fire anything I meant it alright that was a ton of fun and I've got a ton of work to do cleaning up tomorrow but before I go I want to show you one more thing this is a Tesla coil I built and it runs on a vacuum tube it's a special kind of Tesla coil because it's really quiet when I turn it on and I spent a lot of time building it so it's got I did all the wiring pretty much with copper pipe and I think it works great so let me show you and when I show you it turns off all these fluorescent lights up here but check it out haha pretty cool huh oh and you can touch it and if you think that's cool wait till you see this all right here we go [Applause] you sorry guys but I had to ton of fun building this but I don't exactly know how to work it into a video maybe I was thinking about you not get destroy some stop do some cool experiment with the Tesla coil I could teach you guys how to make the same one yourself I don't know there's tons of things you can do so so let me know in the comments below and I'll see if I can make it happen anyway that's it for this video guys see you next time [Music]

Nothing in this title sounds like a good idea. Even for science.

[u/buttery_shame_cave]

That guys yard could be classified as a superfund site by now.

[u/The_J485]

As usual, I love this guy's videos whilst worrying for his and his neighbours' safety. He seriously needs more protection to wear.

[u/Frumpy_little_noodle]

I'm sure the EPA would have a field day in this guy's back yard.

[u/[deleted]]

i love this guy so much

[u/babyProgrammer]

I have a feeling that this guy is going to hurt himself very badly at some point or another. It might be that he's playing with molten metal in shorts and a t shirt but who knows

[u/crusoe]

Well most modern pewter is lead free, but if he accidentally picked up some older pewter at goodwill and mixed into the batch..

Congrats, your home is now a hazmat site.

[u/MacMeDan]

I'm just glad safety is his first priority /s
