Product Description

Everything needed to make a gallium spoon. A minimum of 20 grams of gallium is required to make 1 spoon. Order your quantity required from us, and we'll combine shipping. A. Comprehensive manual with tips & tricks B. Bolts, screws, wing nuts & washers C. Acrylic backing plates D. Silicone spoon mold E. Syringe

Compared to our previous kits, these are placed in a horizontal position, making it much easier to inject the gallium, and reduces spilling.

It's no use buying other spoon molds like chocolate spoon molds sold here on Amazon: gallium is a tricky metal, and only molds that can provide an air-tight seal are suitable for gallium! (the gallium expands while solidifying)

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 and only slightly tighten the nuts (enough to hold the mold together and in place) and then use something like a heat gun or small heating device to warm up the gallium in the bottle and wear rubber/latex gloves while doing so and once the gallium is liquified enough (there may still be a disc but you only need to get half to turn into liquid) turn the bottle on its side or tilt it sideways and put the syringe in to the liquid and SLOWLY draw the syringe back and admit about 2-4ml of liquid gallium into the syringe.
After you've got your liquid gallium in the syringe put it at the base of the mold in the "injection hole" and slowly apply pressure and watch the gallium work its way into the mold.

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.

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.

I found a number of cheaper molds, but I decided to go with this because it was advertised as being made specifically for forming gallium spoons. The product comes with a silicon spoon mold, two clear flat plastic boards with holes and eight bolts to hold the whole thing together. It also comes with very well written and detailed instructions for making a good gallium spoon. I followed the instructions as well as I could, and the resulting spoon was perfect! I used it for a class demonstration and it completely blew them away.

I have never heard of this, but I have a senior who is into science and she wanted the Gallium metal itself
and I thought I should get something that went with it. She loved it. Thanks so much.

I originally bought this for my own amusement but it is an excellent teaching tool as well.
