Gallium prevents aluminum from forming its protective oxide layer. Without that layer, aluminum reacts fast with water. The bubbles are hydrogen gas. The gray residue is aluminum hydroxide. Both are harmless. This reaction is safe but shows strong chemistry. Balanced reaction: 2 Al + 6 H2O → 2 Al(OH)3 + 3 H2 via: Gallium0031/YT #knowledge #chemistry #facts #

Teaching In Videos on Instagram: "The science behind why mercury is banned on airplanes comes down to its destructive reaction with aluminum, the main metal used in aircraft. Aluminum normally protects itself with a thin, invisible oxide layer that stops it from reacting with most substances, even liquid mercury. If mercury manages to touch exposed aluminum, such as at a scratch or damaged spot, it seeps in and forms an amalgam, which is a weak mixture of mercury and aluminum. This amalgam break
