Do you remember what happens when you mix cornstarch and water? You get a great homemade putty: gooey, a liquid yet solid, and wonderful fun.

Cornstarch putty is very washable. The day we did this, the water was off when we went to clean up (leak in the mainline). With a few baby wipes we were okay, and it dries back to a powder that brushes off.  My husband enjoyed this one much more than Peter actually did. Don’t forget the food coloring (a must for half of the kid projects I do). We used orange and put it in an ice cream bucket: I was suddenly craving orange creamsicles.

I was wondering if you could save this: just let it dry out and add more water later. It grew mold, so no. But it’s less than $2 for a box of cornstarch, so still a cheap hour of fun.
