Erupting Sidewalk Chalk

When it gets to be August, it's usually time to find something new to do around here. The girls and I tried out a Pinterest activity last week, and it turned out to be a lot of fun for them, thanks to our neighbor with extra corn starch in her pantry!
My kids know that anything with baking soda and vinegar is bound to be fun!
