ROKiT Bottle Rocket Water Pressure Kit, Pump Action

Product Information

Absolutely. So the reason I'm putting this nose cone on is like what we see aeroplanes, they get aerodynamic, so it goes through the air a little bit easier, less friction. You provide a soda bottle, air pump, tire pressure gauge, and other household items. We also recommend protective safety goggles. When the parachute opens, the air resistance is now more than gravity. This slows down the parachute, and the person can land safely on the ground. Okay, guys. So, next we're going to be making the hoop glider, which I am so excited about because this sounds really fun.

Yes. Yeah. I think we'll make the bra--, the base out of these straws then, do we? Got a bit of tape here. LAUGHS It's in the bag. Now one I have learnt is apparently the reaction is better when it's warm, so you don't want the vinegar to get too cold. You have put a lot in there. Y--you expecting that to fly a lot higher than mine then? Is that what you're--, is that what you're--? Well, let's have a look. Let's...let me grab it. So what we're doing is we're applying a push force to the car. So the air rushes out of the balloon...

Want to use this kit for a science fair project? See our experiment ideas below to get you started. So get a grown-up to heat up the milk in a pan or in the microwave. It should be hot but not boiling. The Sputnik look? I'm going to put a nice bandage around. The thing is, I'm putting so much on mine that it's gonna be quite weighty isn't it? Take the bottle outside and connect the pump to the needle adaptor. Ours wouldn’t stand up on the fins so we rested it on a box, but if you make some strong fins it should stand up by itself. I think, uh Cherry's going to be good at doing the experiments. We, we see quite a lot of that, uh quite often certain things going-- mishaps and going wrong.

If you repeat it several times more will get transferred. You now have tiny amount of static electricity on your ballon. Well, we did it just before we were gonna have the kitchen redecorated, yeah. What about a nosecone? Are you gonna have nosecone? Teddie and science, I, I would not say are um, tremendously uh, happy bedfellows. Only because I don't think Ted does a lot of science at school, so you? She loves it when I talk. LAUGHS Push the needle adaptor of the pump through the cork, it needs to go all the way through so you might have to trim the cork a little bit. A bit. Where's your face? There you go. So you come up trumps there I think. Right, let battle commence.

Next, put another marshmallow into the spoon. Pull the spoon down, stretching your rubber band, and release. Your marshmallow should fly.
