I do a safety demo with calcium carbide and water in a plastic bottle (I use
an old rubbing alcohol bottle) that has a small hole near the bottom. The
calcium carbide looks like an innocent enough pebble, and what could be
safer than water. Combine the two in the plastic bottle, stopper, wait 5-10
sec, and ignite. Good lesson to not do unauthorized experiments.
