An exciting lesson demonstration idea to use in Key Stage 3 and 4 chemistry lessons which illustrates what happens when hydrogen and air react.
Professor Hal Sosabowski uses an explosive mixture of hydrogen and air in a plastic bottle, to show how rockets work, using a piece of drainpipe as a rocket launcher.
This experiment also demonstrates Newton's third law, that every action has an equal and opposite reaction.
Professor Hal Sosabowski is a committed chemistry educator who shows how to safely recreate his inspirational demonstrations, which are both educational and spectacular.
