Water Absorbing Polymer
Just a spoonful of this powder can absorb an entire cup of water and turn it into a firm slush. It's perfect for science demonstrations, science fairs, and magic tricks. It can also be added to soil in potted plants to help the soil retain moisture.

This kit includes a measuring scoop and enough powder to absorb almost a gallon of water.
