- 500g sodium acetate trihydrate
- 50mL glass beaker
- 250mL glass flask
- Clear safety glasses
- Instant Hot Ice activity guide
How does it work?Instant Hot Ice works through a supersaturated solution of sodium acetate trihydrate and water. Once cooled, the solution becomes unstable and can easily be triggered into a hot mass of ice. The release of the sodium acetate trihydrate molecules from the water triggers an exothermic reaction, the heat you feel.
What does it teach?The same science used in the Instant Hot Ice kit is also behind the heat released by hand warmers. The kit itself is a great way to teach about exothermic chemical reactions and the differences between solids and liquids.
How many times can I perform the demonstration?
We include enough sodium acetate to perform the experiment and demonstration 3 times. If you properly recycle your supersaturated solution, however, you can do it a number of times.

My 10 year old (with supervision) was able to complete the several experiments by himself with the instuctions provided. Worked great. He reused the solution twice without issue and there are enough crystals left for several more experiments. We recommend using a scale to weight the crystals to assure you put the right amount in.

THIS IS SO COOL! I was impressed with the experiment from start to finish. I got it for my after school science club, and we had great success. :o)

As long as I followed the directions, this was a perfect experiment. I got a lot of wows! However, when I did not allow the solution to cool sufficiently, there was disappointment! Three out of four...not really bad odds.
Did not work

Tried the experiment several times exactly as the directions stated. Every time I removed the substance from the microwave the powder was still on the bottom in a solid clump and the water was on top. Nothing happened after this. I called and was told "it is fool proof, just follow the directions" I have ordered several things from this company and this is my first disappointment.

I love this product but it takes so long to cool down. once i cool it down smething activates it so it takes forever to prepare. plus you can only re use it twice if more it dosent work.
