top reaches it until there is no more tension and then the top passes the bottom and That's all how it works, but here's the real question: will it happen differently with a longer spring? Well, it turns out I have a longer spring. Let's make the most of it, don't mess it up, so now that I'm awake. at the top of this fire escape Let's try it right 3 2 1 let's go a longer spring still has the same forces working on it the tension of the spring pulling it up and gravity pulling it down it doesn't matter the size of the spring these Forces cancel out for the bottom of the spring until the top meets it, so there you have a spring that almost defies gravity.

Uh, hey, there's no handle on this door. I guess I have to go upstairs. W Sony and I are maxing out the larger hoop glider. and better materials, this is the biggest tube I have, a giant ABS tube and some flexible ones to turn them into hoops, then we put them all together and it's fine, the big hoop is done and the small hoop is also done amazing, not bad , not bad, super solid and That's what we have quite heavy materials, so it may not fly as well as we would like, but something heavy can always be good, right, oh no, that's what I'm talking about, look how It is solid, there is no damage you want to prove.

I think we should, okay, I'm excited, we took our plastic and metal hoop glider outside to try it out and voila, voila 1 2 2 3 huh, huh, it didn't really fly, did it? Sonia and I made a very solid design, but the problem with this became quite obvious, yes it's too heavy, well that's what

science

is, back to the drawing board, mini ma, here's something fun What you can do if you ever get a helium balloon. Now helium balloons float not because they defy gravity but because they are lighter than air it is because the heavier air around it actually falls past the balloon and that ends up pushing the balloon up but what if this balloon of helium was not lighter than air or heavier than air?

I like to just take a helium balloon with a long ribbon and a bunch of clips and add a little bit of weight each time and what we want to do is make this balloon neutrally buoyant, meaning it won't go up or down. but it will be neutral, you'll want to check it from time to time, let's see three clips is clearly not enough five clips is five clips is pretty close, it can still float down, so you'll want to take off just a little. of weight maybe around there look at this you just take the balloon and put it somewhere and it stays it stays still it doesn't go up it doesn't go down it's not attached to anything now let's maximize it eh, I had a big balloon and it was a had a oh, there's a giant balloon and look, it's a great device for delivering paper towels, say you wanted a paper towel, here you go,

science

, yeah, don't worry about Ramona, just put it up, put it up, yeah, higher, good.

Hey, grab gravity, gravity makes things fall, but where do they fall? They fall towards the center of the earth, it fell, didn't it? So the Earth causes gravity, yes, gravity, oh come on, everything that has mass has gravity, gravity, but the Earth has so much mess that the gravity produced by everything else is like nothing. I mean, forget it, but let's say I was in space with this chicken, I would have gravity and I could exert a gravitational force on this chicken and if I get my angles. true, maybe I can make the chicken orbit me like a moon, look at my chicken Moon, eh, gravity, but let's be serious, what causes gravity, we don't know, but what we do know is that without gravity there would be no universe like we.

I know no you no me no chicken Moon I would miss my chicken Moon chicken Moon you want gravity whether you like it or not the universe wouldn't exist without it you like the sign I'll give you a good deal uh half off go back to our hoop glider, which was too heavy, this is what I don't understand, this is heavy, but I can still lift it and throw it. Yes, a plane is much heavier. You could never lift a plane, but you can fly and that's because planes have engines. so it has a constant source of thrust when we throw it, we only have one source of initial thrust, so we throw it eventually it loses its energy and thus falls to the ground.

So we need something that is light, lightweight and something that is strong and sturdy, okay let's see what we can find, okay Sony and I try a plastic tube and some strong paper, we make rings and secure them with some tape adhesive and we ran out to try it. Dan, okay, 3 two. A woo, that's pretty good, that was awesome, let's try it again. Here we go. I launch the hoop glider and although it doesn't keep flying forever, it goes much further than our first version and also further than the tube could have launched on its own. pretty good, so we've done a good job of making something that flies, why don't we make a couple different types with different materials and see if we can get one that flies even better than this one.

I think it's a good idea. idea, yeah, okay, let's do it like this and I've created a pretty good hoop glider at its best, but we wanted to see if different materials would make one even better. Sonia made a much lighter version, this time I used cardboard and made this a little heavier one, let's do it, okay, three, two, one, not bad, my turn, here we go, okay, that didn't go very far , right?, okay, so now we can measure it with the one we launched before, look, and it turned out nice. So far, this went quite far to see if we have a better design.

Here we go, wow, amazing, so heavy, you know, light, not interesting, no, this design seems to be the best. I keep thinking about how you talked about drive, yeah. All the thrust we can put in is only what we can put in with a single launch, yeah what if we could give it more thrust than that? How can we do that? I don't know, like some kind of slingshot or something like a It has to be a pretty big slingshot, a pretty big slingshot, but I think it sounds cool, although I think I can make a big slingshot for this, why not?

Okay, high five, let's do it. This is an egg. Eggs don't like to be dropped. Oh, fortunately, we can. Use the power of science to design something that will keep the egg safe as it falls. Look at my egg drop. Gadgets. What I really like about this experiment is that there is no wrong way to do it. You can come up with any design you want and see it. if this one works here is a bunch of helium balloons this structure is just to keep the helium balloons on so the egg can land very gently here goes who H and the egg is miraculously unharmed sounds like one worked very well success this is a giant helium balloon which I think will work pretty much the same because I think this balloon will fall slow enough that the egg can touch each other and nothing will happen so that didn't work and then there's this one that has there is no deceleration, everything is designed to absorb the impact and the idea is that the cone will crumple and absorb the force when it hits the bottom.

No, oh no. I think it would have worked if it hadn't spun in the air, but I did it and well, I guess the egg is completely broken, so I'd call it a failure. This is the parachute. You see that the egg has been placed in this foam container and this is a parachute that will hope

full

y slow down the egg. Woohoo uh- oh wow, very good and that one seemed to work well, yeah, the egg is totally fine, the parachute worked well. egg drop experiment totally fun experiment to do but the question is how do we maximize it and the answer is pumpkin drop, same thing except with a pumpkin instead of an egg come on ok drop the pumpkin with everything attached in one go, okay, here we go, done one, two, three, so what we've learned from this is that the heavier something is, the more force acts on it from gravity. which means the harder it is to slow down when you're falling, okay, it's fair that you beat this gravity, but I'll beat you next time.

I'm going to get a broom. Being a chef is my absolute passion and cooking is science. recipes is my specialty I am busta and this is cooking with science oh hello welcome to cooking with science I am busta delicious nothing is more important to have fresh than your seafood is what makes the difference between a fresh fish ah and one that is not so fresh yes You live by the ocean, you probably know that the water has high tide and low tide, look closely, it's the same amazing place, but did you know that this is caused by the gravity of the moon and the sun?

Say this cookie. It's the Earth and this happy little guy is me hello and this rope represents the water around the earth if we didn't have gravity to worry about the water would all be equally deep around the earth But here comes the moon this mushroom now the moon has gravity and that pulls the oceans towards it a little bit so it creates a high tide there and a low tide here and a little hit of high tide on the other side of the earth and as the Earth spins and I'm on it, I experience low tide and high tide and low tide and high tide very interesting but there is another factor the sun or this lemon now the sun also affects the tides but not as much as the moon now the sun does not affect the tides as much as the moon because it is much further away but it still has an effect if the sun were here then the tides would move away a little like this and the tides would be less severe but if the moon and the sun lined up like here there is a very, very high tide and a very, very low tide, like this that there it is, this is how the tides are affected by the gravity of the Moon and the Sun M delicious I am Bika and thank you for joining me in scientifically cooking our hoop to the maximum The glider was working quite well, that was incredible, here we go , but we could only give it so much oomph by throwing it, so we came up with the perfect scientific solution of Max, our giant slingshot.

Alright, we pull the bungee cord back and hook it to our hoop glider I'm ready to shoot Calm down three two throw it W very nice our slingshot is amazing at giving the glider more thrust, meaning more energy at the beginning, so which goes faster when we launch it, the glider rises into the air and flies. a long way that was great so there you have it, giant hoop glider, yes, science, Max's experiments overall, very well done, what more could you ask for? Well, my turn, hey, until next time.
