Fun and Affordable Summer Fun
Something new and different that got them away from the screens (computer and television).
So easy and inexpensive. I got the old muffin tin at Goodwill for $2. Then in each cup we mixed 1 Tbs. Cornstarch with 2 Tbs. Water and several drops of food coloring. (The neon food color worked great.)
This can also be a great time to teach about mixing colors.
My kids were entertained by this for at least an hour.
They were almost equally entertained washing it off the next day with a watering can. Rain would do the job too, but we wanted a fresh canvas to do it again.
