Very interesting and entertaining video. In it, the authors show an interesting chemical reaction. Take supercooled melt sodium acetate, which in contact with roughness or salt (on the surface of the skin) begins to enter into a reaction, resulting in instant crystallization throughout the volume with the release of heat.
