Summer sure doesn’t let up in Georgia, does it? This is definitely the hottest place I have ever lived.  The heat has me scouring the web for new ideas to keep cool and have fun.  Lately I’ve been stumbling upon creative ideas for chalk and outdoor play. I have three words for you… Erupting Ice Chalk! I bet I have your attention now!

Here’s what you’ll need:

  • Equal parts water, cornstarch, and baking soda. (You can start out with a 1/3 c. of each)
  • Food coloring
  • Vinegar
  • Ice cube trays
  • Squeeze bottle

Mix together the water, cornstarch, and baking soda. You’ll end up with a nice white base that will make vibrant colors.  Split up the mixture into different bowls (based on the number of different colors you want to make.) Add food coloring to each of the bowls and mix.  Pour into ice cube trays and freeze until solid.

Here’s where the fun part begins! Take your kids outside and let them go to town stacking, sliding, and painting with the melting ice cubes. You can hose off the driveway or sidewalk beforehand to make the paint spread more quickly and easily if you want. Once the cubes are sufficiently melty, squeeze some vinegar onto the colorful mess and watch it erupt!  The best part is you can hose down the cement, and voila! No mess!

Erupting Ice Chalk is a science experiment, an art project, and a way to beat the heat all rolled up into one super cool activity.
