Melting Gallium

This is Gallium. It is a silvery metal used in semiconductors and LEDs, but the cool thing about it is its melting point, which is only about 85 degrees Fahrenheit.
If you hold a solid gallium crystal in your hand, your body heat will cause it to slowly melt into a silvery metallic puddle. Pour it into a dish, and it freezes back into a solid. Cool, huh?
