Gallium

I admittedly have no idea what this is actually used for, but its pretty frickin’ cool! Gallium is a non-toxic metal that has a melting point of around 85 degrees Fahrenheit. Since the average body temperature is around 98 degrees, this metal will actually melt in your hand! It’s reportedly used in some medication and pharmaceuticals, but that’s beside the point. We don’t really care if it has a purpose in human society, just that it looks really awesome!
