If you repeat it several times more will get transferred. You now have tiny amount of static electricity on your ballon. 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... Next, put another marshmallow into the spoon. Pull the spoon down, stretching your rubber band, and release. Your marshmallow should fly. The negative charge on the ballon or comb attracts a positive charge in the water so pulling the water closer. Now, we're going to be making a marshmallow catapult. What we're going to be needing is five marshmallows. So, we can--

To launch, hold the hoop glider in the middle with the smaller hoop at the front and gently throw it. Rice is slightly elastic and so eventually when the blade is pushed in, the compact grains will bend tightly against it, allowing you to lift the jar using only the handle of the knife. I did some stuff with Blue Peter which ended up as a complete disaster, glitter everywhere including in the camera lens.

Oh it's like being on Blue Peter, where's a dog? My cone's a bit too small, ah I'm gonna have re-cone. I'm re-coning.

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. 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. 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? You've actually created casein, which is Latin for cheese. The casein in the milk does not mix with the acid in the vinegar, so it forms blobs. Push your third marshmallow onto the tied end and make a mark on this marshmallow. And, make a mark on it. Put an X on it. 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...
