An introduction to the properties of H2O and its components: hydrogen and oxygen. This clip also explains that water has highest cohesion of any nonmetallic liquid, which allows other substances to stick to it.
Jimmy and Lucy Liu perform science experiments with Kevin Delaney, including making a giant cloud using the power of chemical reactions. Kevin explains each experiment and the science behind it. As they introduce elements such as Hydrogen, Sulfur hexafluoride, and Nitrogen to the experiments, Kevin identifies the properties that make them unique.
Beakman explains catalysts using demos involving glue and hydrogen peroxide. He explains how catalysts make things happen faster than normal. He proves that catalysts aren't depleted in a reaction by adding in more hydrogren peroxide during his demo and watching the reaction occur again without the need to add more catalyst.
