At the beginning of the summer we make a list of things we want to do and places we want to go over the summer. Brittany was super dilligent about making our list this year. We like to do some science type experiments. Pinterest was great for this kind of stuff and so she found this recipe for frozen chalk. Basically it was cornstarch, water and food coloring that she put in ice cube trays and froze.
Then the kids took it out into the hot sunshine and let it melt!
Of course after it melted the cornstarch goo was pretty fun to play with too.
