At the start of the science roadshow they talked to us about gravity and how it works, and did some demonstrations, like putting a cup of water on a plate with strings attached to it, and swung it around, the cup of water stayed on the plate even when he swung it in a loop and over his head.
And then after that, they let us wander around and look at little science setups. my favourite one was probably the bed of nails, the bed of nails was a bed of nails sticking up, which are quite sharp, but you don't get stabbed by any of them.
Then they called us back and told us about atoms, they create up everything in the universe. they showed us some reactions that can happen if you mix some of them together. when they mixed some of them and blew them through fire, the fire turned blue, pink, and red. And then they lit something on fire and it exploded, it looked like a small atomic bomb mushroom.
And then they but "elephant toothpaste " in with foam, and it shot up in the air and kept going, and started spilling out of the cups they were in, luckily they were in a bucket.
