Cotton Ball Rocks

Abstract

Aim:

They start out soft and fluffy and end up hard like a rock! Count, sort, stack them; kids will have a blast with cotton ball rocks! They can create a rocky dinosaur land with them. Also, they can have super heroes throw them with their super strength and power!

Materials required

  • cotton balls
  • 1 cup of flour
  • 1 cup of water
  • food coloring (optional- you can paint them when they come out of the oven to look like real rocks)

Procedure:

1. Mix up the flour, water, (and food coloring).

2. Dunk cotton balls one at a time in your mixture (fully coat them).

3. Spread them out on a greased cookie sheet. (You can also arrange them close together to create shapes or letters).

4. Bake in a 300 degree oven for 45-60 minutes.

Preserve and treasure your rocks or crunch them open by stepping on them! They are crunchy on the outside and still soft and fluffy on the inside!
