I am really looking forward to making some cool stuff with this. It's going to blow my daughters minds :)

From Amazon: InstaMorph is an advanced modeling compound that melts in hot water or air (140 deg F) and solidifies at room temperature. When warm, it acts like clay, but when it cools it resembles a strong plastic. Unlike other products that once they dry they are locked in that shape forever, InstaMorph can be reheated over and over again and re-molded into any number of configurations.
