(saturated solution) 3) Place test tube into a beaker filled with 150ml tap water. 4) Heat with Bunsen burner but don't let the solution boil. 5) Cool test tube in a beaker filled with cold water for about 2min. (supersaturated solution) 6) Using tweezers, gently drop ONE SINGLE CRYSTAL OF SODIUM ACETATE into this solution. This will begin the spontaneous crystallization. CAREFUL THE TEST TUBE WILL FEEL HOT.

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?
