This is just one of the six experiments we took part in at a science fair run by nottingham university chemistry department. We went as part of a home ed group and sam had blast. We did everything from making a calculator work using fruit and veg to making slime and hitting people with frozen flowers! This is the experiment with liquid nitogen. Sam was chosen to demonstrate how brittle the flower becomes after being frozen. He just couldn't believe that he was going to be allowed to hit someone without getting scolded for it.
