Maybe you love peeps. Maybe you hate them. Maybe 10 packages of them somehow wound up in your house this Spring and you'd really love if your kids didn't eat them all! We have a "solution"! Make play dough with them (no detergent or borax required).

Ingredients and Materials:

  • One Sleeve of Peeps (5 Peeps) 
  • One Tablespoon of Oil
  • Corn Starch (5-6 Tablespoons) 
  • Microwave Safe Bowl
  • Measuring Spoon
  • Fork to stir


1. Place 5 Peeps into a microwave safe bowl and pour One Tablespoon of oil over the Peeps. 

2. Put the bowl of Peeps and Oil in the microwave for 30 seconds. 

3. Add one tablespoon of cornstarch to the warm Peeps mixture and stir. 

4. Stir in one tablespoon of cornstarch at a time until the mixture begins to form a ball. Lightly dust hands with cornstarch and begin to kneed the dough. *CAUTION* The mixture may still be warm/hot. An adult should check the temperature first.

The Science behind PEEP Slime

Science Description and Recipe from: Little Bins for Little Hands

So when you heat up a marshmallow or a peep {which is also a marshmallowy candy} you heat up the molecules in the water that is contained within the marshmallow. These molecules move farther apart. This gives us the squishiness that we are looking for to mix up our Rice Krispy squares or our peeps slime.

This is known as a chemical reaction between the heat and the water in the marshmallow. When you add the cornstarch, a natural thickener, you make a thick stretchy substance which is known as the great peeps slime! Your hands playing, kneading, stretching, and generally having fun with the slime dough keeps it going.

What happens after awhile to this peeps activity? As the peeps slime dough slime cools down, it’s going to harden. The molecules in the water move closer together again, and that’s that.
