My daughter and I just got the sodium acetate today. We put some in near boiling water and stired alot. Put it in fridge to cool - tried it - it did'nt work. Did it a second time - its in the fridge now. Her science fair is due in 3 days! I only bought 500 grams and its going fast!!! Please e-mail me if you have made it successfully - with exact instructions please help. Running out of time and sodium acetate! Thanks Hi there: HOT ICE …………..

I have the sodium acetate and used tap water boiled a lot of the sodium into the water oured into a flask, cooled and poured into a dish...Nothing happened! Could you PLEASE help.

I'll bet your question has already been answered. Temperature: It will work at room temperature or lower (but as it gets colder there's a greater chance that it will spontaneously crystallize.) Suppliers: As has been mentioned by previous posters you can find sodium acetate already pre-mixed in the right proportion with water (very little water, actually) as heat packs. It took about 5 seconds on Google to find these online suppliers (I Googled "heat pack"): http://www.amazon.com/Instant-Reusable-Pack-Heating-Packs/dp/B000F3Q524 http://www.9thtee.com/reheater.htm I'm trying to reason out how snapping the metal disc starts the crystallization. My current theory is that the shockwave aligns the acetate ions which starts the ball rolling. (Non-spherical particles suspended in a fluid will align during any shearing flow. This is sickeningly close to work I did for my Master's thesis. Don't ask.) Anyone else have any ideas? Before you ask any more questions why don’t you read all the posts?

What was I thinking? I also forgot to mention, sodium acetate is a hydrate (which means that the crystals already contain a fair amount of water). This is why you don't need to add much water to get it to dissolve. You can also make your own NaCH3COO (get used to different nomenclature!) It is the result of the well-known "kitchen" reaction of baking soda (sodium bicarbonate, NaHCO3) with vinegar (acetic acid, CH3COOH). You have to use distilled vinegar--no balsamic here! Use excess baking soda to react all the vinegar, filter out the unreacted baking soda, then boil the solution to drive off as much water as possible. Remember, you won't see the crystals until it cools. Whoops, that should have been NaH3CCO2. What was I thinking?

Distilled or deionized water would be best but you can do it with any filtered or bottled water. The main idea is that there can't be any "junk" floating around that could start the crystallization process before you want it to happen. Clean, well-scrubbed glassware is also a must for the same reason. Make a bunch of small samples because one or two may crystallize on their own no matter what. I start by filling a few small test tubes with the NaH3CCHO then adding just a few drops of water to each (that's all it takes). Heat them up in a hot water bath and stir each with a glass rod. When entirely dissolved, take them out and let cool to room temperature (NO FRIDGE NECESSARY!) As long as no dirt gets in you can use the same samples over and over. Just reheat. Good Luck.
