Envisioning Chemistry: Bubbling IV (Super Slow Motion)

Hydrogen bubbles are generated when zinc of various shapes reacts with hydrochloric acid. This film shows this chemical reaction in super slow motion shot with a high-speed camera at 3000 fps. At normal speed, it is difficult to observe the rise, fusion, and rupture of the hydrogen bubbles, which are extremely fast. By slowing down 120 times, these processes become vivid and magical: some bubbles swallow others as they rise, some bubbles bounce off each other, and some bubbles jump up and down when they reach the liquid surface.
