Oh gallium, you absolute weirdo. This metal – which is somewhat similar to aluminum – has an incredibly low melting point of just 29.8°C (85.6°F), which means that it can quickly transform from a solid to a liquid if you grip it in your hand.

The intrepid people at Let’s Melt This decided to, unsurprisingly, melt some gallium and place it on a Bluetooth speaker. The temperature of the speaker was just around this melting point, which means that as music blared through the room, the gallium was constantly changing from a liquid to a solid, creating some decidedly funky landscapes.
