Hot Rocks

We decided to do an at home activity today and I have wanted to try hot rocks for a while so I told the kids to grab their scooters, we are going on a rock hunt. That is harder than it sounds, we were looking for the big, round, flat stones, but they do not seem to be here in Texas. We "borrowed" a few extra rocks from around our house instead. We cleaned them off and stuck in them in a 350 degree oven for 15 minutes whild the kids tore the paper off of a few crayons. I made sure to inform them over and over that the rocks would be hot and not to touch them unless you use a hot pad! We got the rocks out and the kids drew on them with crayons. It was pretty cool to watch the crayons melt as they drew on them. It was more like they were painting their rocks with the wet crayon wax. This was a cheap, fun activity!
