Obleck

Have you ever experienced Obleck? It is quite interesting, to say the least. You know how you stir together corn starch and water to thicken food? Well....that's Obleck! Although, I have to admit that I have never placed my hands into the stuff prior to this evening. Squeezing it or applying force to it creates a solid substance, but release the pressure on it and you have a liquid again. Obleck.......a great time to be had by all!

Recipe:
1 cup cornstarch
1/3 cup water
2 to 7 drops food coloring (optional)
Mix water and food coloring together. Slowly add cornstarch. Do not stir. Let the mixture stand for 1 to 2 minutes. Pick a handful of the oobleck up and squeeze it until it forms a hard ball. Open your hand and the oobleck will turn from a solid back into a liquid. If it gets too dry after awhile, just add a bit more water.

Note: After allowing the mixture to "sit for 1-2 minutes" it was solid. We did need to add small amounts of water at a time and mix with fingers just until it became a liquid. This worked great and was easy to do. Enjoy!
