Are you interested in a fun project for a rainy day? Try turning rocks and old crayons into masterpieces.
Heat rocks in the oven at 325 degrees for 15 minutes (smooth rocks work best). The rocks will be hot to the touch, but not dangerously so. Use hot pads just in case, to protect your kitchen table.
Then color with old crayons. The wax will melt on contact, producing a beautiful paint-like effect.
Both my preschooler and third grader had a lot of fun with this activity. My daughter thinks we are going to trick the Easter Bunny!
