# Demonstrate Newton’s Third Law of Motion | Science Projects

Have you ever been on a skateboard? Now, think about it. When you’re on the skateboard, to get the
skateboard to go, you move your foot backwards and the car goes forwards. That is exactly how rockets work. There’s an action; you going back. And there’s an opposite reaction, you’re
going forward. Now think about a rocket ship. Something is pushing down, and the rocket
goes up. But do rockets always have to go up? Could we make a rocket go, that way? I want to show you how we can make a rocket
balloon car that works on the exact same principles as a rocket ship. There’s an action, and there’s an opposite
all the stuff pretty much in your home, paper that I’m going to use just to make the body. And I’m only going to show you how to make
the body and attach the wheel. And then I’m going to show you one that I
have already made before because I don’t need to show you how to make the walls and all
that extra fun stuff. But making the body is important because you
want your rocket balloon car to move fast. So, I’m going to make my rocket balloon car
skinny and long and has to have wheels and axles. So, look what I’m going to do, candy. I’m going to show you how I could use regular
candy and straws and create something called a simple machine. So we’re actually making two connections,
okay; flying rockets, simple machines. And I’m going to take a straw, and I’m going
to attach it to my paper. And you could tape it down or you could use
glue. I’m going to use an actual glue gun just because,
to me, I think it works better. I’m just going to glue it down. This is going to be my axle. Cars do not just run with their wheels, right? The wheels are attached to something. I’m going to push this out, just like this. And then, I’m going to put this back here. And now I have my axles done. Now, they’re a little too long. So, what I’m going to do is attach my wheel
and attach my wheel. Now you need something to hold your wheels
in place. And that’s where your Scotch tape comes in. It could be masking tape, duct tape, any tape. And take a piece of tape and you’re going
to wrap it around just so that it becomes thicker than the hole of the candy. And now your wheels cannot escape. And then, you’re going to do it two times,
three times, and four times. Trim off your ends. Trim off your end. And you’re going to do it to this side and
this side. And then, you’re going to have your wheels. But the cool part is you can have fun. After you’re done, you could build walls to
your rocket balloon car. You could make it pointy so that it can cut
through the air. But how’s it going to move? Well, one balloon and my straw, and I’m going
to make a rocket balloon car because right now, I have my car. And I have this simple machine to wheel and
axle and it’s ready to rock. Now I’m going to take my straw, I’m going
to cut about an inch of the balloon. I’m going to wrap the rubber band five times. But if you wrap the rubber band too many times
around the straw, the straw will close, and the air will not be able to go into the balloon
or out. So, you’ve got to be aware of that. One, two, three, four, five – I’m going to
try six. Now, I’m going to test it and listen to see
if any air is escaping and if it’s not, let the air out. And now, I’m going to attach my rocket balloon
to here. And I’m going to tape it down. Now some of you still are not getting what’s
