Here it is, but take it from me and just don’t do it. See, it sounds so deceptively simple. My boys stirred the 1 1/2 cups of water into the 16 oz. of cornstarch and suddenly it all seized up. “Hey, this isn’t working! It said to knead it together with your hands.” Naturally I plunged my hands into the mass to knead it and instantly got a traumatic flashback from years gone by.
Back then I was working part time at a bulk food store and occasionally there was a need to scoop corn starch from a large bag into smaller sized bags for the shelf. The first time I was assigned that job, I scooped right into the powdery stuff. It squeaked and felt silky and hard at the same time and my every hair stood on end in horror. I was too embarrassed to tell my boss that I would rather do anything else, please just let me wash up the floors on my hands and knees. Anything else. That day I got cornstarch overload and I got really good at being busy whenever it needed to be bagged again. Anytime a recipe calls for cornstarch, I am very, very careful with spooning it out. I get a nasty little chill just stirring a few tablespoons into liquid.
But after reading how neat this stuff is, today I dug my fingers into the oobleck, then shuddered and quickly went to the sink to wash the mass off my hands. The children found it terribly fascinating, how it gelled and wept and turned mysteriously solid by turns. I let them make a huge mess all over the kitchen because I knew cornstarch washes up very easily. My oldest son couldn’t believe I tolerated the drippings and spills. He got a spatula and tried valiantly to keep it in one spot on the table, to corral it into a bowl, just anything to contain it. “Mama! They even have it on the wall! Make them stop.” He was nearly frantic so I reassured him and sent him out of the room until the little girls were done having fun. They tiptoed into the bathroom for a full scrub down and then I cleaned the kitchen for the second time today.
This is one “neat” experiment that is definitely not for the faint of heart. I guess next time we probably will just pass on it.
