Blue Goo Fun

Are you up for an art adventure that’s messy but loads of fun and teaches a little science? On one of my summer visits to my granddaughters it was too hot to go outside. So Juliet got out her
National Geographic Little Kids Magazine and said: “Let’s make Blue Goo, Baba!”

We probably should have followed the directions and covered her art table with lots of newspapers. But since it’s washable, we just put our supplies right on the table. We used one large mixing bowl, a measuring cup of water, a box of cornstarch, 4 small bowls, and a box of neon food coloring.

In just a few minutes we had whipped up a large bowl of white goo. We divided the goo into the four small bowls, added about ten drops of food coloring into each bowl and the fun began. The weird goo hardens in your hands when you squeeze it and feels like a solid. When you open your hands, the goo feels like a liquid and rolls out of your hand. Juliet squealed and giggled as she squished her hands into the bowl, happily enjoying the physical sensations of the “goo.”

Two hours later we had four bowls of greenish, bluish, reddish goo all over our hands and smiles on our faces. Reluctantly, we cleaned up the mess but promised to make it again with Amelia next year.
