Quicksand/Oobleck

Make the letter Q and dinosaurs come to life by making quicksand also known as Oobleck. We use small dinosaurs and let them sink into the quicksand. The kids try to pull them out-it’s much harder than you think.

You will need:

1 box of cornstarch

water

Directions:

Begin by pouring 1 1/2 cups of cornstarch into a metal tray. Add 1 cup of water. I prefer to mix this by hand. Add drops of water if necessary. It is the right consistancy when you can pick it up and make a ball then open your hand and it seeps through your fingers.

The science: Mixing cornstarch and water create a non-newtonian fluid. It acts like a liquid when being poured but a solid when pressure or force is placed upon it. You can mold it briefly. If you made enough of it, you can walk across it. The best part is that it washes away with water. Kids and adults love it.
