Summer of Mess: Oobleck

IMG_6257One of the most basic science/sensorial projects. Mix water and corn starch and it makes this funky liquid/solid. It will drip and run, but it also becomes firm if pressed, patted or squished into your hands. 

This project went a lot better than the marker explosions and entertained Cam for 30 minutes. Plus she asked to do it again! I put down a splat mat on the kitchen floor then dumped a box of cornstarch into a tub. I had Cam pour the water in and mix, first with a spoon then with her hands. We got out some dinosaur figures and our plastic play dough toys. I also threw in a colander. There ended up being a bit too much water so it was a little too runny, but it sat out on a warm day and by evening the consistency was a lot better. Ultimately it didn’t matter, Cam loved it.

…know that if it falls on the floor it will dry fairly quickly and can be easily swept up.

…add some food coloring. I didn’t have time or the inclination to do that, but it would make it even cooler. 

…add the water slowly. I didn’t know the ratio so we just poured and mixed. This lead to oobleck that was a wee bit too runny.
