Science Max | PASTA & ROCKET | Full episodes

Have you ever done a scientific experiment? You wondered what it would be like if you did it big. My name is Phil and I take your everyday

science

experiments and make them big. These are scientific facts. Experiments that take something weak and make something strong. we build things on a grass, sand and paper to show how

science

can be used to make something strong out of something weak, dry, wet and science said, and that is how it is built today based on scientific facts, experiments in general , oh hello, science maximized, have you ever done it? I've been eating

pasta

and was wondering what I could build with this.

Could you build something that can support an impressive amount of weight? I have and that's what we're going to do today in the Science Max experiments in general, but we're not going to use cooking

pasta

. Since it's too delicious, we'll use raw pasta, which is less delicious, but great for building. We are going to make a pasta bridge. This is how you do it. First, you need to start with a plan and then make your money. I'm saying positive, but of course spaghetti is usually the best thing to use and then put it into your plan.

The reason you have a plan is to make sure all the spaghetti is exactly the right length. Place them on your Plan perfectly aligned like this and now it's time to glue it all together. Now you can use white glue, but it is time consuming, so I suggest a hot glue gun, but make sure you get permission from an adult before using one of these. you take your plan, you design it, you stick it, don't stick it on the paper because that will be bad and you will end up with your shell and it will look like this.

Now remember you want sides because those are the sides. of your bridge and as you can see I used several strands of pasta because that will make it a little stronger once you have your trusses. It's time for the next part of the plan. This is the road and it works the same way. roll out your paste, glue it down and bam, now place your beams in your way and glue them all together and you also want to put some struts on top here, probably to keep it nice and stiff in the end, you'll be done.

We have a fantastic looking pasta bridge, pretty good, huh? Paste bridge, no other bridge could claim to be 100 percent paste: the glue 99.8% paste, 0.2% glue. I say the captain sailed for the land of fossil bridges now, if that were nice. fast for you, don't worry, all the instructions will be on our website. Now a bridge isn't a bridge unless it spans a space because that's what bridges are for, so you put your pasta bridge there, across the books, like that and then. you can see how much weight the bridge supports. It's pretty impressive if you build it right, even something flimsy and as delicate as pasta can hold quite a bit of weight.

I like to use big heavy blocks and place them in the middle where there is no support from the books at all and I just keep adding heavy things and see how much weight the bridge will hold before breaking. How long will it hold well? I'm not going to tell you that's where you can maximize the science and find out for yourself. and now we're going to max it out today in oh my pasta, today in max science experiments in general, we're going to see how fragile things can become strong if you build them right, we're also going to max out the Pasta Bridge Experiment to see if we can make one that's Strong enough to hold me.

Do you think we can do it? I know I have no idea, but I'm going to the Skills Development and Training Center to find out. Oh hey, cut to Phil, hi Ewan. Great, thanks, great, this is Kyle, he has a master's degree in civil engineering. Do you want some pasta? I'm fine. I can go back to get more. I'm really fine. So what does a civil engineer do well? A civil engineer builds the world. All around us they talk about our houses that keep us warm in the winter our roads hey even our bridges bridges that's fantastic because for that I need your help we want to maximize the amazing pasta bridge I want to make one big enough to be able to cross it Okay, that has never been done before.

I know, do you think we can do it? We will need a lot of help to do it. Oh, we don't need help. All we need is a lot of pasta that I have, ha ha, how good. You say yes, let's try it? Okay, we'll try. I will do that. Why don't we take a little to start and then to maximize our paste bridge, the idea is to take a lot of strands. of pasta and keep gluing them so that the long beams of pasta on our giant bridge are nothing more than many regular sized strands of pesto, this is where we were after 20 minutes of gluing there, that's good, yes, I think this piece It's well made, so how does it work?

It's strung up. Let's leave it. Yeah, I think this will be cool, so we just need to build a few more of these. So, yeah, that's right, how many more 212 or 212 of these more? That's right, but it took like 20 minutes to do this one, yeah, oh, well, I guess, I mean, these are maximum scientific experiments in general, that's what we do, we just keep building and building and you know, I don't have any plans to the next. one, so, uh, Phil, yeah, I think there's a better way to do this. I would love to know that there is a better way that would be faster than this, much faster.

Sure, let's make it awesome. I'm just going to put the pasta back in the bag because it's Dale, you don't have to do that, no, no, but it's going to get old, so I'm going to call one of my friends, we're probably going to need more help with this, oh man, it's great idea, sorry. a great idea because it's theirs, yes, well, because at least we could ask your friend to help us clean. Building sand castles is fun, but you can't use dry sand because it doesn't hold up very well, you have to use wet sand.

Even if you use wet sand, it does not hold much weight, but if you use sand with the power of science, it does hold the weight. dry sand, wet sand, science and this is what's going on, it says that these ping-pong balls are grains of Sand when it's dry doesn't hold together very well, that's why you can't build a sand castle with dry sand, but if you wet it a little, the sand grains will hold together a little better. The surface tension of water is why it is 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 for example this paper sandpaper, it will hold the weight, so here's what you do: take your Windows screen and cut it into circles.

Make sure you get permission from an adult first. Well, put a layer of sand, pack it and place it in a circle of the Windows screen and a layer of sand, pack it in a circle. of the Windows screen, then you guessed it, layer of sand, pack it in and circle a window screen. The window screens will add more friction between the grains of sand and make your sand castle strong with the power of science and then you can put many. of weight and there you have it, sand with the power of science, okay, I had to max it out, let's see how strong science is and it really is our shepherd bridge.

It was going to take a long time to build it with individual pieces, so we have a new plan hi Michaela hi Phil how are you I'm great, how are you okay? This is Michaela, she's an industrial engineering student right now and you and Kyle have a new plan for how we can build our pasta bridge that won't look like this. It's the best Kyle and I could do with 20 minutes, well, it better be okay, I'm glad how we're going to do it, so instead let's try something like this, oh, okay, this is like a giant donkey. something like that, yes, but we are going to build the bridge from this exactly, we will make it longer, although yes, we will make it eight feet long.

We have this long pole, yes, and we have sheets of this pasta. Let's put them diagonally, okay, let's regulate it, let's start from this corner. I'm going to keep rolling, okay, water, together, rolling, rolling, rolling, we're going to keep doing this with a bunch more leaves so it gets really long, like eight feet long and when we finally finish rolling, we have to spray it. with a little bit of material, yeah, and that's how it holds everything up really well and then it'll be this thick, yeah, when we're done with this. It's going to be one of the deck parts of our bridge, cool, so each of these big pieces is going to be like a single strand of pasta and the little bridge, yeah, we need a lot of these.

Oh, many, still, it's much faster than doing it. piece by piece with this every time I pick it up you make that noise the shape of something makes a big difference in how strong it is get some toilet paper rolls and lay them out in a square and then stack books on top of them that can hold The theme of weight is that they can actually hold a lot more weight than you probably think, in fact the amount of weight that just paper in a tube can hold is really impressive, aha, and now let's max it out, girls, wait for the rolls of toilet paper, hmm, no. the bills wait for the toilet paper rolls to arrive, no, the bills weigh in six rolls of toilet paper, no, the bills weigh in 10 rolls of toilet paper, ha, ha, ha, ha, ha, the weight of the bills can be supported by 10 rolls of toilet paper, but what you build jumps, ha ha, it didn't really work, Kyle. and Mikayla's plan is to use a long stick and sheets of raw pasta we roll the pasta around the stick and spray it with a little varnish we roll sheets and sheets of pasta along an 8 foot long stick making many layers of paste then we wait to dry and relieve the pole, what we have is an 8 foot long hollow tube, a paste that becomes one piece of the bridge, then we join a bunch of these pieces together and use more sheets of paste to glue them together in the way we use.

For our little pasta bridge, we are making our giant pasta bridge by wrapping sheets of pasta around the posts using the technique we just used, making a big pull with many, many sheets of pasta wrapped around each other and we have made a giant trust look at this, this is cool guys, it looks pretty good, yes, if I hit it, would you think it would stay together, yes, this is pasta, not steel, it's just made to hold you, how, what do you think are the chances of that this? It's going to support me when we build it, something like 50/50, not bad Micaela, what do you think I'm going to support for the best, hoping for the best?

That's exactly the kind of gray area we like to work in at Science Max Experiments in general. experiments in general, I don't know if anyone has done this before that I know of, so we have no idea if it's going to work well, so one more of these because these are the sides, yeah, a road and then the top yeah, yeah okay let's do it while we wait this is a good time to point out one of the things that makes our bridge really strong which is the triangles as you can see the truss or the side of our bridge is actually just three big.

Triangles Triangles are very strong shapes to build and work very well in bridge science. So simple a caveman could do it. This is a caveman, today we are going to teach this caveman how to build a strong structure, he goes ahead and builds a shelter and I. I'll go back and see how it worked no, no, that's not now, you need to build walls by stacking boxes on top of each other, that's how it's built, you understand. Oh, is that okay with you? Yes, look at those boxes. stacked on top of each other, yes, but if they are in tall stacks, what would happen if you pushed on the wall?

Wow, don't stay on top if you build like that, let's try again. This time I'll help you set the foundation where your wall should go well now let's make a second level no no don't put it right on top you need to stack in the middle that's how you make us strong well oh come back later right? why do not you try it? It seems strong. but you forgot a box, join us next time we talk about how to make a door. Building a door into a wall is difficult because how do you make a big hole in the wall without the wall falling down?

Well, people have come up with a lot of things. There are many ways to fit doors and windows in walls made of stone blocks over the centuries and you can do it at home with books like I am doing or with building blocks, just go up until you are happy with the height and then stacked side by side. layer a little bit closer to the middle until the final layer touches like this and then you take a big heavy book and you drop it right on top of it and it's pretty stable and you just made a door, it works even better if it's part of a wall because You want extra weight on the outside of these books, so of course I had to build one that was part of a

full

wall.

This is the same cantilever arch built with small building blocks and as you can see I got closer and closer together until they meet at the top and it is very strong ha ha now let's maximize the type of arch we are in building is a cantilever arch and the Science Max construction team and I are using pieces of wood cut to different lengths. How high can it go? We can also use my head.a cage for greater safety in the back and we open the valve, the air that escapes could have enough force to push me, this is two cubic meters of air, if we put it in a balloon, the balloon would be this big, but if If we put it in a balloon, the balloon would be this big, but if we compress the air, we can put it all in one of these, a steel tank, this is what we'll use next for our air-powered car.

Got it, yeah, okay, so Sarah and I have been working hard and building the air. motorized car we can't call it a balloon pirate card anymore because now we have a compressed air tank, so it's not exactly a balloon that powers it, so I'll just sit here. Sarah will turn on the tank and I will. I'm going to go and before we do this we should say under no circumstances do you try this at home we are trained professionals you ready I'm ready okay high five first okay now we're doing it right so before we turn on the tank , make sure your feet are down and the brakes are on, I have to take them off until I say, you have everything ready, okay, yes, yes, it worked, but I feel like it could work better.

You want to go faster. I want to go faster. Reminds me of the stone chariot, yeah, well, we didn't have a big enough balloon. We need more strength. We need more strength. So if we get a bigger tank, let's get more tanks. More tanks. More strength. You will advance faster. Newton's third law. Newton's Third Law High Five, okay, let's get it right, this is Newton's Cradle and it's a really cool toy that demonstrates all kinds of laws of motion, including Newton's Third Law. What you do is play with this ball and when it hits. These balls exert force on that fault so that it stops moving, but it exerts force on these balls that travels through the ball and makes it so in the end it is like this, now there is a lot going on here, but you can really see how the force It's the same, the one you put in and the one you put out, if you use two balls, I swing two balls up and two balls go up that side at that moment, now it wouldn't be signed to the maximum unless we maximize it, so come on, okay , this is one that we built with bowling balls, bowling balls, bowling balls instead of smaller balls and I think it will work the same way, let's figure out that you throw one and yes, it works the same, okay now? let's try it with you boss, okay, we're ready, wait, wait, wait, and two balls throw them and two balls on that side, all good, equal and opposite reaction, so our only pressurized tank created enough force to move me, but no very quickly, the plan now is First do two things: we will triple the amount of thrust using three tanks.

We'll also use some tubes that lock together to give me an initial push. These tubes slide together and when the air is turned on. The pressure in the pipes will cause them to slide, which will push me forward. After that, I use what's left in the tanks to move forward. Now is the time to maximize it. I have had the help of a few more people from Science Max, thank you. Thank you very much Corey, you will see that we now have three tanks of compressed gas and we also have this nifty little gadget, how does this work?

Sarah. Okay, each tank is connected to a tube and you can see that each tube goes into it. a main pipe so when we activate them the pressures will increase that and we will move forward with more force well that's cool and Reed is stacking cinder blocks thank you Reed up that will push the pipe push against the cinder blocks and then I. I'll go that way, okay, are you ready? I'm ready. Okay, let's do it again now. I have to say thank you Corey. I already have it. This is something you definitely don't want to try at home.

We are all trained professionals. We have a physics degree here, we have TV people making sure this is safe, so watch it and enjoy it, but please don't try any of this at home, okay, I'm ready, Sarah, count three two, that It was incredible. It was really amazing, okay, high five, yeah, yeah, yeah, and it's raining now so it looks like we're going to have to stop, so thank you so much for joining us for general science experiments in our third law episode. of Newton, maximum science. It's a show or we take small experiments and do them in a big way.

If you want to try these experiments yourself, visit our website for instructions, but not all Science Max experiments are the type you should try at home. This yes, this no, try this gift. Don't try this, big yes, big no. I don't know how you could do this at home and remember, if you're ever unsure, ask an adult, thanks for watching the best science experiments in general, wait, I can play Mary. a little lamb is working Newton's cradle on a bowling ball, come on, you know this one
