Study in Gallium 3
Another of a series from having some fun with liquid metal.
Gallium (Ga) melts at slightly warmer than room temperature (to be precise, 29.77 °C or 85.59 °F). Basically, it melts in your hand.
In this case, I used a base of black acrylic (perspex) and experimented with dropping some liquid Ga on it. Some interesting shapes resulted.
