Cornstarch play

This activity is perfect for a hot sunny day. Here’s what we did…you can modify amounts depending on how many children are around!

7 children
5 boxes cornstarch
Aprox. the same amount of water.
Dump your cornstarch into a large container. Hold one box in reserve just in case you add too much water. Start adding water gradually while the children mix with their hands.

Add water and keep mixing until it is the consistency of pancake batter. Your mixture will become more fluid as the kids work it with their hands.

Cornstarch and water make a magical concoction. If you hit it with your hand, it feels hard. If you grab a clump, it feels thick like clay and if you try to pick it up, it dribbles from your hands in streams.

The kids loved pouring it on their hands and legs and even rubbing it on their faces. It dries very quickly to a clean powder. I had a group of kids aged 3-10 and they all had fun playing with this stuff!

The kids in my backyard used a 100 gallon horse trough to clean up. I used a garden hose to spray the picnic table clean and the leftover gunk went into the compost heap!

Add some watermelon slices and your sunny afternoon is complete!

  1. Looks like a great way to spend a summer afternoon! Cornstarch just went on my grocery list.

  2. We use this as a rainy day indoor activity:

  3. We call this 'goop'. These holidays we added food colouring to it and my youngest boy and his buddies had a ball playing with it. Then the chickens got in on the act and thought it looked like something interesting to eat – we had chickens with little green goopy beaks!
