There are the ones that are gel filled bags. There is a clicker in the middle of the bag. Press until you hear it click.
The bag will begin to harden as warmth is released. Once totally hard you can use it as a weapon and bang someone over
the head with it if they bother you. L.O.L. Just kidding. Once harden, you take and place in a pot of boiling water until the
hardened material returns to a gel like consistency . Ready to use again. Very Nice.
