ROKiT Bottle Rocket Water Pressure Kit, Pump Action

Product Information

Oh no, no. This is a challenge Carol, I've got to try and beat you somehow. That's about enough, isn't it?

I didn't expect it to fly so high, I've gotta say that. But, it's just a little tweak, Trevor, that's all it takes sometimes, a little tweak. Why? The sciency bit. Spinning the bottle makes the water inside spin like a whirlpool. INTERRUPTION It makes a long, thing v-shape in the middle down into the cap. This is called... That doesn't make any sense to me, what you've just said, but I'll--I'll--, again, I'll take your word for it, mate. Want to use this kit for a science fair project? See our experiment ideas below to get you started.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. I think mum, I'm sorry but I don't think you'll be as good at science because you just don't like mess. Let's put the witches' cat in the t-- green slimy swamp. If it floats, it's a witch. If it sinks, it's a witch.

Happy. Where's your face? There you go, so you come up trumps there I think. Right let battle commence. Why does this happen, is you don't need to apply much pressure the first time you push the knife into the rice, as the grains sit loosely in the jar. So as you can, we've got two identical cars. They are all ready to go. One car has one balloon. The other car has two. Now what we're gonna do is we're gonna race these cars against each other and see if my car gets to the finish line before Naomi's. Are you all set? If it's icy outside our front door, so that you don't slip over I put alt outside, so that it defrosts the snow. So how's this gonna turn into ice cream?A bicycle pump. I'm gonna add extra air inside the little thing and hope that it will increase the reaction. It could go terribly wrong. 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. 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. Science is a wonderful, wonderful thing, and I don't think that people should think, oh only my teachers and my parents and scientists can do sciencec, I'm just a kid, I can't really do that.

One the entire length of the long side of the card and 2.5 cm wide. The other approximately 10 cm long by 2.5 cm wide. Darcey let's see what was happening there. When you rubbed the balloon on your hair a few electrons are transferred from the hair to the balloon. I'm not so sure, but the fact that you're covered in vinegar, I think that has to give it to me. But, remember this, Dan, we both beat you.Put your hovercraft on a flat service. Carefully let go of the balloons and give the CD a little push. I like science because it's about food. You know what, you cook food, there is something scientific about it. I like reactions, and I like playing the kid.
