Re: Explosive
"[...] where its explosive energy is tamped by the weight of the water above and quite effectively splits the bowl in half."
Newly qualified junior chemistry teacher demonstrating how sodium reacts with water to leave it alkaline. First attempt - litmus strip dipped in the water stays neutral. Bigger lump of sodium put into the special mesh container on a handle. Lifts it out of water - shows it fizzing - indeed sparking. Loud bang and the pneumatic trough splits neatly into two halves and a bottom. Loud cheers from the class.
A few years later the VIth Form doing work in the chemistry prep room. Sudden sound of a bang followed by a cheers. A new junior chemistry teacher had repeated the experiment.
