Watch Gallium 'Dance' on a Speaker
Gallium is one metal that knows how to boogie.
The team at Let's Melt This decided that melting gallium would be far too simple. After all, it readily melts in your hand thanks to its low melting point.
So they set the 100 grams of metal on top of a Bluetooth speaker and let the bass make things interesting. Their macro lens captured the sound waves flowing through the metal in a spectacular fashion.
