thanks a lot! I'll try all the suggestion and I hope to come with something positive!

well today I tried the experiment with sodium acetate and water but it didn't work. I used sodium acetate from a chemistry lab (so it is pure...), I put sodium in boiling distilled water for a super-saturated solution: 160 gr in 30 ml of water and I left it on the heater for some minutes. i put the solution in fridge but the solution crystallize in few minutes instead of stay fluid and i cannot use for make instantly "hot ice"... where I made a mistake?!? thanks a lot!
