Gallium spoon melting !

Gallium spoon melting !

To make this trick you just need a very pure gallium spoon (99.99% pure !) easily obtained by Gallium and spoon molds.

Then put it into not concentrated acid... but just hot water ! And you will see the spoon melts to a liquid puddle in only few seconds !

Explanations :

The melting point of the Gallium is very low : less than 30°C ! So, everytime you move beyond this temperature the Gallium changes phases from solid to liquid ! You can also make this transformation just by holding Gallium in your hands.
