Half baked? Don't have all your marbles? Here's a craft for you.....

Have you ever wondered what happens to marbles when you bake them and put them in ice water? Neither did I. But I ran across this craft and loved the cracks that happen ONLY on the inside of the marbles. Clearly the lighter color is better and I will look for some others in different shades, these are the only two I could find (with Rhea's help) last week. Basically, bake in the over at 350 degrees for 20 minutes then immediately put in ice water. Make sure the baking dish and the bowl holding the water are metal. I glued on end caps to hold an "o ring" and add to any chain or ribbon of your choice. If you have an older child (you know your child's capabilities on being around hot things) it might be a good science lesson at the same time. I read you can also use the glass "stones" you find for aquariums, but that I have not yet tried.
