I'm sure you have old broken crayons...or new broken crayons because your 2 year old thinks it's funny to break them in half!! This was a rainy day craft a couple weeks ago.
It kept some little hands busy peeling paper off the crayons.
Melt them in the tray in 30 second intervals. The silicone does get HOT!
I froze them, so the boys would get to see their creations faster.
