Science videos always work best when high energy reactions are involved, if the video uncovers a new scientific mystery all the better.

Take for example the Invisible Metal experiment that demonstrates the effect of mixing two alkali metals, sodium and potassium, with water. Strangely the high speed camera also captures the moment this ball of liquid metal turns almost completely transparent for a brief moment before it explodes.

Presented for your viewing pleasure is the high energy experiment that produces transparent liquid metal in spectacular slow motion. Sit back, relax, and let the chemical reactions begin.
