Most of these items you can get at the Dollar Store or you may already have at home.

Debbie Chapman, with One Little Project, likes to “use a rainbow assortment of colors to create something beautiful.”


  1. Pour water into a clear cup and top it off with shaving cream.
  2. In a few small one to two ounce containers add water.
  3. Then add different colors of food coloring into each small container (several droplets).
  4. Last, pour SMALL (super tiny) amounts of food coloring over the shaving cream using a syringe, eye dropper, or small measuring spoon.

By squeezing the small droplets over the shaving cream you won’t over saturate it or melt it too fast.

Watch in AWE as the gorgeous colors trickle through the shaving cream!

Items Needed: 1 can of shaving cream, Food coloring, Water, Clear glass, Small 1 to 2 ounce size containers, Eye dropper (you may also use a syringe or small measuring spoon)

9. Make Homemade Butter

Activity by: Mommy Poppins

I remember doing this activity when I was in 1st grade (probably because I’m a butter fanatic).

We all sat in a big circle and passed around a wooden jar that had heavy whipping cream in it.

Each of my classmates and teacher got a turn whipping the heavy whipping cream with the wooden jar stick.

By the end, we had butter! I was truly amazed.

My taste buds were in heaven as we got to enjoy that on bread with jam. 🙂Make Homemade Butter

This recipe is super quick and easy …


  1. One jar with a lid
  2. Pour heavy whipping cream into the jar
  3. SHAKE, shake, and shake until you have whipped butter!

The smaller the jar the faster it will take to make your butter.

For instance, a baby jar takes about 10 minutes to whip up.

For faster results or to support kids with upper extremity challenges, use a hand mixer for blending the heavy whipping cream in a bowl.

Items Needed: Jar with a lid, Heavy whipping cream OR bowl, hand mixer, heavy whipping cream

Promotes: Fine Motor Skills, Taste, Encourages focus
