What Is a Gallium Spoon?

A gallium spoon is a utensil made out of low-melting point metal as a prank. The melting point of gallium is 85.6 degrees Fahrenheit. If served as teaspoons to unsuspecting guests with a hot beverage like coffee or tea, the spoon will melt upon contact.

More practically, gallium as a spoon can be used as a safe and relatively non-toxic method of illustrating the concept of melting points in a classroom setting. Along with academic settings, gallium is used widely in the electronics industry.

Elemental gallium is not naturally occurring, but gallium (III) compounds are found in zinc and aluminum ores.
