Gallium Spoon Mold By Rotometals

Best way to get the job done

After reading “Disappearing Spoon” I couldn’t help but want to make a disappearing spoon of my own, however, I was reluctant to spend this much on a spoon mold for a gag (as cool as it is). I tried building molds from clay, silly putty and wax but they were messy, not really reusable and produced a poor replica. After a couple weeks (and April Fool’s day was quick approaching) I gave in and dropped the cash to do it right. I was glad I did. It worked perfectly with no mess and produced a great gallium spoon for only a few minutes worth of effort. This is really the best way to do it.

By the way, gallium expands slightly when it solidifies so don’t store it in a glass test tube.

Chemistry pranks have never been so fun…

At first I was a little hesitant to pay this much for a mold of a spoon but since you can use it over and over I think it’s worth its price!

PROS:

-Only need about 3ml (via syringe) or 10g to make one spoon

-Looks exactly like a real spoon

-Will trick someone into believing it’s a real spoon (so beware)

CONS:

-The instructions are in English but they are poorly written both grammatically and spelling wise… Read them but then be advised it might take some trial and error

-The mold will leave your spoon with a little excess material at the end of the stem of the spoon so try not to over-inject the liquid gallium or you’ll get jagged distortion unless you put exactly the required amount

I have made 3 spoons already (I ordered 40g of gallium and still have some left after 3 spoons) and I am impressed with the results… The way I have found that works best is to use the plastic pieces and assemble the mold and wing-nuts together…

great gag

It was a little difficult to get it right. But after three attempts the spoons came out gorgeous! The trick is to preheat the assembled mold and tighten only loosely. After filling with gallium only half way up the handle, tighten until a bead forms on the top.
