The two raw materials: baking soda and vinegar, used to make hot ice need to be free of impurities. Ensuring this is very difficult, which is why it is better to purchase ready-made sodium acetate. You can purchase it from online stores like eBay, Trade Me, etc. Sodium acetate is also available in warming pads, hand warmers, etc. Just cut open these pads or hand warmers with a knife and empty out the contents. However, sodium acetate obtained from these warming applications will appear like a gel. Nevertheless, it satisfies the purpose. Moreover, purchasing ready-made sodium acetate simplifies and speeds up the entire hot ice making process.

Requirements
•Sodium acetate powder (One cup)
•Water
•Steel saucepan
Preparation Procedure

Step 1
In a steel saucepan, add two cups of water and begin heating it. Now, gradually add a cup of sodium acetate into the water and stir, so that it dissolves. Do not add it all at once. Instead, add it gradually, ensuring all the crystals are getting dissolved.

Step 2
The solution should not be brought to a boil, instead must be heated on low heat. Do not overheat the solution, or else the solution will develop a yellowish or brownish tinge on solidifying. This will not look so appealing in a science fair, as it will not resemble ice.

Step 3
Keep stirring the solution, as you add sodium acetate crystals. Now, the key here is getting a supersaturated solution. This is because, if the solution is not supersaturated, when the solution is placed in the refrigerator, it will crystallize, thereby defeating the whole aim of the experiment.

Step 4
Since we are looking for a supersaturated solution, we need to make sure no more sodium acetate crystals dissolve into the water. You will know the solution is supersaturated, when some crystals remain at the bottom of the beaker or saucepan, even after stirring for quite a while. This indicates your supersaturated solution of sodium acetate is ready.

Step 5
You can also do it the other way round, wherein, you can first add sodium acetate into the beaker and then add water gradually. However, be careful not to add too much water. read more »
