Getting Ready

To prep for our PEEPs® slime science experiment, we first gathered our supplies:

  • PEEPs® candy
  • Powdered sugar or corn starch
  • Clear corn syrup
  • Microwave-safe bowl
  • A forkLove Peeps®? Then you will love this easy Peeps® slime science experiment!

That’s it! The prep was as quick and easy as it comes.

Homemade PEEPs® Slime

To make the slime, we began by placing 8 PEEPs® bunnies into our microwave safe bowl. We put the dish in the microwave and cooked it for about 1 minute – making sure not to cook it any longer.

I used our hot pads to carefully move the bowl to our table. Then my kids stirred until the colors mixed and the PEEPs® looked like marshmallow fluff.

Then we added eight teaspoons of corn syrup (one teaspoon of corn syrup per PEEP® used). We mixed until the ingredients were well combined and added eight teaspoons of cornstarch.

At this point, our slime was stretchy. We experimented by adding a little more corn starch to make the slime less sticky and more dough-like.

Although we didn’t need it for our batch, you can add more corn syrup if you need to make your slime more stretchy and runny.

When we found the perfect consistency, the kids eagerly began playing with the sticky slime. They loved making shapes and watching the slime run through their fingers.

The Science Behind It

PEEPs® are marshmallows covered in sugar. Marshmallows are made by mixing sugar, gelatin, heating it until it boils, then whipping the mixture allowing air bubbles to form.

When marshmallows cool, the collagen from the gelatin prevents the structure from collapsing, leaving a sticky, puffy candy.

When you melt marshmallows, all the air is removed, leaving a sticky, gooey substance.

Adding more sugar and corn syrup changes the viscosity (thick, stickiness) of the PEEPs®-

  • Add enough dry ingredients and the slime becomes doughy and returns to a solid state.
  • Add enough corn syrup and the PEEPs® will be transformed into a runny liquid with low viscosity.
