Demonstrating Chemistry - Spectacular Experiments: Dry Ice - The Magnesium Sandwich

Using two blocks of dry ice, Prof Hal Sosabowski demonstrates how magnesium is so reactive that it can cause carbon dioxide to act as an oxidant. The result is a beautiful instense glow inside the blocks. This experiment is one of the rare occasions in which carbon dioxide actually promotes a fire rather than putting it out. Prof Hal Sosabowski is a committed chemistry educator, evangelist and communicator. Hal shows us how to safely recreate his inspirational demonstrations, which are both educational and spectacular.
