ROKiT Bottle Rocket Water Pressure Kit, Pump Action

Product Information

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

Mummy's very good at cooking, uh which is also quite science-y. And Daddy's good at like, knowing like facts. LAUGHTER So I think they're both gonna-- I think they're both gonna be very good.So get a grown-up to heat up the milk in a pan or in the microwave. It should be hot but not boiling.

When the three skewers meet at the top, use a bag tie to tie all three skewers together close to their ends. 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. 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.

As air escapes from the balloon it is pushed through the holes you make in the bottle cap and the CD in all directions because of the shapes, smoothness and weight distribution of the hovercraft the escaping air creates a thin cushion between the CD and the surface. The cushion of air dramatically reduces the friction between the CD and the surface and allows your Next, put another marshmallow into the spoon. Pull the spoon down, stretching your rubber band, and release. Your marshmallow should fly. Each time the handle is pushed into the rice, the friction increases, opposing the force of gravity.

Oh no. LAUGHTER Why, the science-y bit. When an object falls there are two main forces acting on the falling object. Well, when you turned up with a bicycle pump, which was like cheating. I mean, if they said I could've had a bicycle pump--. Well, we did it just before we were gonna have the kitchen redecorated, yeah. What about a nosecone? Are you gonna have nosecone? Yeah, alright. We'll go with that. Bicarbonate of soda, here we go. Let's see how we go here, mate. 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?

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. This is really good because we're actually doing it rather than watching it, you know. We're actually going to try and do these things. It will be very interesting.
