This happens to be one of the cheapest ways to make your slime. You can make a batch of slime then once you have it already prepared, you can add some rock salt in it to make it crunchy. You can either use the naturally occurring rock salt or you could go for the colored ones. Colored rock salt creates beautiful, highly reflective slimes that you will have fun squishing. It makes for an amazing sensory activity and works as a perfect seasonal science.
