Another great activity for rainy days and bored kids. Warning - very messy! Not for carpet play!

Ingredients Nutrition

  • 1 12 cups cornstarch
  • 1 cup water
  • 1 (1 ounce) package unsweetened Kool-Aid powdered drink mix


  1. Mix all ingredients together until blended.
  2. Goop should harden when squeezed in your hand. (sometime it needs a little extra water)
  3. I recommend strong, bright colored kool-aid to give it color and smell!

My eldest son is very into science right now and he loved this (no kool aid here in Australia, so I left it out). Thanks for posting.

We left the kool-aid out of it because I'm a lazy mom and didn't want to deal with any stains, but this was SO SO SO cool! We saw it on Ellen and I wanted to try it with the kids. I did have to play with the consistency, but it was awesome. The picture I took, my son just hit it hard with his fist and my daughter has her hands sunk it so you can see how weird this stuff is. We had a BLAST! Thanks for sharing.
