Science Max | BUILDING A BRIDGE - PART 1 | Science Max Season1 Full Episode

have you ever done a science experiment and wondered what it'd be like if you did it big i have [Music] my name is phil and i take your everyday science experiments and do them big this is science facts experiments at arch science facts taking something flimsy and making something strong whoa pasta bridge we build things out of pasta sand and paper to show how you can use science to make something strong out of something weak dry sand wet sand science sand it's all how you build it today on science facts experiments at large oh hi science maximites have you ever been eating pasta and wondered what could i build with this could i build something that could hold an impressive amount of weight well i have and that's what we're gonna do today on science max experiments at large but we're not gonna use cook pasta because it's too delicious we're gonna use uncooked pasta which is less delicious but it's great for building we're gonna make a pasta bridge here's how you do it first you want to start with a plan and then you want to take your pasta i'm saying pasta but of course spaghetti is usually the best thing to use and lay it out on your plan the reason you have a plan is so that you can make sure all of the spaghetti is exactly the right length lay it out on your plan perfectly aligned like that there and now it's time to glue it all together now you can use white glue but it takes a long time so i suggest a hot glue gun but make sure you get an adult's permission before you use one of these okay so you take your plan you lay it out you glue it up don't glue it on the paper because that will be bad and you will end up with your truss and it looks just like this now remember you want two sides because those are the sides of your bridge and as you can see i've used several strands of pasta because that'll make it a little bit stronger once you have your trusses it's time for the next part of the plan this is the roadway and it works the same way lay out your pasta glue it up and bam there it is now you put your trusses on your roadway and you glue them all together and you also want to put some struts along the top here probably to keep it nice and rigid in the end you will end up with a fantastic looking pasta bridge pretty good huh no pasta bridge no other bridge could claim to be 100 pasta minus the glue 99.8 pasta 0.2 glue i say that captain set sail set sail for the land of fossil bridges now if that was pretty fast for you don't worry all the instructions are going to be on our website now a bridge isn't a bridge unless it spans a gap because that's what bridges are for so you put your pasta bridge up there across the books like that and then you can see just how much weight the bridge holds it's pretty impressive if you build it right even something as flimsy and as delicate as pasta can hold quite a bit of weight i like to use big heavy blocks and put them in the middle where there is no support from the books whatsoever and just keep adding heavy things and see how much weight the bridge will hold before it breaks how much will it hold well i'm not going to tell you that's where you get to be science maximites and find out for yourselves and now we're gonna max it out today on oh my pasta today on science max experiments at large we're gonna be looking at how fragile things can become strong if you build them right we're also gonna be maxing out the pasta bridge experiment to see if we can make one that's strong enough to hold me you think we can do it i know i have no idea but i'm going to the center for skills development and training to find out oh hey kyle phil how you doing great thanks awesome this is kyle he's got a masters in civil engineering uh did you want some pasta i'm good i can go back and get some more really i'm good okay so what does a civil engineer do well a civil engineer builds the world around us talking about our homes keeping us warm in the winter our roads hey even our bridges bridges that's fantastic because that's what i need your help with i want to max out the pasta bridge awesome i want to make one big enough that i can walk across it okay that's never been done before i know right you think we can do it we're gonna need a lot of help to do that yeah we don't need help all we need is a lot of pasta which i have haha nice what do you say yeah let's give it a shot okay we'll give it a shot i'll do why don't we just take some to start and then in order to max out our pasta bridge the idea is to take many many strands of pasta and just keep gluing them together so the long beams of pasta in our giant bridge is nothing but many many regular size strands of pasta here's where we were after 20 minutes of gluing there that's nice yeah i i i think this piece is done okay so how does it work is it is it strong well let's give it a go eh yeah i think this will hold great so we just need to build a few more of these then right yeah that's right how many more 212 more 212 of these more 212 that's but it took us like 20 minutes to make this one yeah oh well i guess so i mean this is science max experiments at large that's what we do we just keep building and building and you know i don't have any plans for the next while so uh phil yep i think that there's a better way of doing this i would be delighted to know there's a better way it'd be faster than this much faster sure let's do it awesome i'm just going to put the pasta back in the bag because it it failed you don't have to do that no no but it'll get stale phil i'm gonna call in one of my friends we're probably gonna need some more help with this oh man that's a great i sorry that's a great idea cause it's it's there's yeah good because at least we could get your friend to help clean up better sand castles in 80 seconds sand castles is fun but you can't use dry sand because it doesn't stay up very well you have to use wet sand but even if you use wet sand it doesn't hold a lot of weight but if you use sand with the power of science it does hold the weight dry sand wet sand science sand here's what's going on say these ping-pong balls are grains of sand when they're dry they don't hold together very well that's why you can't build a sand castle out of dry sand but if you get the sand wet a little bit the grains of sand will hold together a little better because of the surface tension of the water that's why it's easier to build a sand castle with wet sand but they still won't hold much weight but if you add something that creates even more friction between the grains of sand like say this sandpaper it will hold the weight so here's what you do take window screen and cut it into circles make sure you get an adult's permission first okay deal put in a layer of sand pack it down and put in a circle of window screen and a layer of sand pack it down circle of window screen then you guessed it layer of sand pack it down circle of window screen the window screens are going to add more friction between the grains of sand and will make your sand castle strong strong with the power of science and then you can put lots of weight on it and there you go sand with the power of science [Music] okay i had to max it out let's see how strong science sand really is [Music] huh science our pastor bridge was going to take a long time to build out of individual pieces so we have a new plan hey michaela hey phil how you doing i'm great how are you good this is michaela and she's an undergrad in industrial engineering right i am and you and kyle have a new plan for how we can build our pasta bridge that's not going to look like this this is the best that kyle and i could do with 20 minutes okay well i have better good i'm glad how are we gonna do it so instead of that we're gonna try something like this oh okay this is sort of like a giant burrito kind of thing right yep but we're going to build the bridge out of this exactly uh we're going to make it longer though yep we're going to make it eight feet long we have this long pole right yep and we have sheets of this pasta we're gonna put them on the diagonal okay and we're gonna roll it but we're gonna start from this corner and we're gonna keep rolling and don't forget to add water now we gotta add water i'll add the water okay adding water just like this yep it helps the pasta to stick together so as we're rolling we're rolling rolling we're going to keep doing this with a bunch more sheets so that it gets really really long like eight feet long and when we're finally done rolling we gotta spray it with some varnish yep and so it all holds together great and then it's gonna be about this thick yeah when we're finished with it exactly this is gonna be one of the parts of the deck of our bridge great so each one of these large pieces is gonna be like one single strand of pasta and the little bridge yeah we need a lot of these a lot a lot still it's a lot faster than doing it piece by piece with just oh every time i hold it up you make that noise oh awesome [Music] the shape of something makes a big difference in how strong it is get some toilet paper rolls and put them in a square and then stack books on top of them they can hold wait thing is they can actually hold a lot more weight than you probably think in fact the amount of weight just paper in a tube can hold is really kind of impressive [Music] and now let's max it out [Music] you
