My eighth grade chemistry teacher got in trouble for an experiment she did for us. We were standing in the middle of a soccer field, with goggles and aprons on, as we should be. She dropped a baseball-sized piece of pure sodium into a bucket of water, to show us how violent some chemical reactions can be. If you haven't seen this done, it's very cool. The sodium and water react with each other, producing loads of hydrogen. The heat from the reaction ignites the hydrogen. That one lump of sodium made a 4-foot diameter fireball above the bucket.
