Pranks can be a lot of fun. Especially those that use science. The Gallium Spoon Mold will let you create teaspoons that will melt away as your guest stirs their tea.

Gallium is a silver colored metal with a very low melting point. The melting point is just slightly above room temperature so your average cup of tea would be boiling to this metal. The Spoon Mold allows you to make your own spoon from the substance so that you can play a little trick on your friends.

The set comes with everything that you need to mold a spoon. The hardware, syringe and backing plates are all in the box. The only thing you will have to buy is the Gallium itself. You will need about 20 grams of the metal in order to make a single spoon. If you choose to use it on an unsuspecting friend, don’t let them drink the tea! Other than a fun joke, you can also use this to teach people about science. Or just because melting a spoon is cool. The Gallium Spoon Mold is $56.98.
