Prof Hal Sosabowski demonstrates this simple yet effective experiment, which reveals several properties of solid carbon dioxide. Hal shows us how clouds of water vapour can be formed, how carbon dioxide is denser than air, how a gas occupies much more volume than a solid, and how dry ice sublimes - turning directly from a solid to a gas without becoming a liquid. 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.
