- sodium polyacrylate
-can be found in disposable diapers
-can be found in garden materials
Step 1: Buy
If they are, buy them. After you open the pack of diapers, you may be wondering where the sodium polyacrylate is.
At the bottom of the diaper, there is a part where there is a packet of a white powder sewn in. Cut open the diaper and pour this material into a container! Do the rest with the rest of the diapers.
Step 2: Mad Scientist Part
Sodium polyacrylate 'snow' feels cold to the touch because it is mainly water. You can also make it extra cold by putting this "snow" into the freezer and waiting 10 minutes. The snow will not melt, instead it will dry. If it dries out, you can rehydrate it by adding water.
It should look something like this:
Step 3: Why?
Sodium polyacrylate, also known as waterlock, is a polymer with the chemical formula [-CH2-CH(COONa)-]n widely used in consumer products. It has the ability to absorb as much as 200 to 300 times its mass in water. Acrylate polymers generally are considered to have an anionic charge. While sodium neutralized polyacrylates are the most common form used in industry, there are also other salts available including potassium, lithium and ammonium.
