This theory is now supported by photographic and mathematical evidence, published in the journal Nature Chemistry. In a laboratory at Braunschweig University of Technology in Germany, Mason and other chemists used a high-speed camera to capture the critical moment that makes an explosion inevitable: a liquid drop of sodium-potassium alloy shooting spikes into the water, dramatically increasing the reactive interface. They also developed a computer simulation to model this event, showing it is best explained by a Coulomb explosion.
The Youtube video chronicles the evolution the experimental apparatuses underwent over time, pursuant to keeping the explosions safe, contained, reliable, and visible.
