Leprechaun Slime








Those tricky leprechauns were at it again, concocting a putty that changes shape right before your eyes just in time for St. Patrick's Day. It transforms from a solid to a liquid then back to a solid over and over again. Cameron and I had a blast creating this using just 3 simple ingredients found in the kitchen: cornstarch, water and green food coloring! Cam is into anything science and I was hoping to come up with something for St. Paddy's Day so working together this is what we came up with:

We combined 1/4 cup of cornstarch with approximately 4 TBS of water premixed with a couple drops of green food coloring. Slowly add colored water to the cornstarch in a small bowl, stirring constantly. Add enough water until mixture is no longer crumbly and holds shape. Pick up putty and roll and pound in your hands. Dough should get firm. Relax your hand and dough should turn to a liquidy goo. When mixture starts to dry and no longer spreads out to liquid just add a few more drops of water to keep the fun going!! To add a little smart to the fun explain that the green slime is a referred to in the science community as a Non-Newtonian liquid, meaning it is a non conforming substance which can be either a solid or a liquid, depending on how much pressure it receives.
The mess cleans up easily with warm water, so enjoy the tricks in store with our Leprechaun Slime!
