Oobleck Silly Putty

April 14, 2020

I’m sure you are familiar with oobleck…that’s the official name of the cornstarch + water concoction that defies Newton’s third law of motion, which states: for every action, there is an equal and opposite reaction. Push on it with force and it acts as a solid. Hold it in your hand and it becomes a liquid, falling through your fingers. My kids love to make oobleck, so when I stumbled on this combination for oobleck putty, I knew they would love it!

This recipe replaces the water with dish soap, and the result is a silly putty like consistency that still has the same effect of being both a solid and a liquid.

Ingredients:

  • 1/4 c. corn starch
  • 3 Tbs dish soap
  • food coloring (optional)

Combine in a bowl and stir with a spoon until well blended. Then, use your hands to mix it completely until it turns into a putty. Because the amount of water varies by which brand of dish soap you use, you may need to add a little more cornstarch, or even a little more dish soap to your mixture to get the right consistency.

My kids played with this for quite a while! We left it in a bowl overnight, so it did dry out a little. But, I added a tiny bit of water to it the next day, and it was good as new!

Tag me on Instagram or Facebook if you make this oobleck silly putty! I’d love to it!
