Pouring a Liquid Mirror in Slow Motion

Soft, silvery, not toxic, and atomic number 31 on the periodic table of elements, Gallium is famous for its low melting point: 29.7646 °C or 85.5763 °F. In other words, it can melt in your hand.

In this Slow Mo Guys video, Pouring a Liquid Mirror in Slow Motion, Gav and Dan “get some mesmerizing T-1000-like shots of Gallium splashing around.” See the diamond-like shapes it forms as it’s poured. Plus, see what it looks like bouncing on a speaker and a large drum in all of its slow motion glory.
