So how do you keep the kiddo entertained when it is truly too hot to play outside? While back-to-school shopping at Target last week I had a mini-brainstorm. I found a cute silcon ice cube tray for a buck and crayons were on sale for 50 cents. Instead of using my traditional method of melting crayons into shapes in the toaster oven, I decided to see if they would melt in the car, on the dashboard.
I broke up the unwrapped crayons into small pieces and filled the lightning bolt shaped molds. The kiddo and I carefully set them on a small tray and put it on the dashboard of my car, which was paked in my sunny driveway. We closed up the car and waited. We checked them after about an hour to see that they were melting. After a bit over two hours they were completely melted. I brought them back into the house and stuck the tray into the freezer to firm them up. They are now great lightning bolt crayons! We did it a second time with other colors too.
This experiment led to a safety discussion as to why its important to not stay in a closed up car in the heat. Not that my son would ever do that, but I thought it was still a lesson to hear.
