This is mine and the kids first attempt at making ivory soap crayons in containers instead of jello molds. I found the how to on the internet.
First unwrap a bar of ivory then put it in a bowl and put it in 4 minutes and watch it expand five times its size into a cloud
Then add a little warm water till it sticks together in a ball. then add the food coloring and then put it in the mold or containers. Just let the kids have fun
