Oobleck is a non-Newtonian liquid. Don't ask me what that really means. It's a liquid and a solid. You can squeeze it into a ball, but when you open your hand it drips through your fingers. It's really messy, but it washes up easily with water. If you are a fun mom, you won't really mind if your kids do it in the kitchen.
If you are a control freak like me, you'll send them out to the driveway.
Start with 1 part water and 1.5 parts cornstarch. We had to keep adding cornstarch.
It's hard to stir.
Just start mixing with your hands.
It's drippy, stringy and gloppy. You can pick it up. You can drizzle it.
It's hours of fun.
My kids would still be out there if it weren't for the black thunderclouds that rolled in.
Happily for me, the rain will wash the mess away.
Now that's fun for everyone!
