Oobleck was the name given to a type of slime in a Dr. Seuss book that was capable of gumming up a whole kingdom. The oobleck that you can make for a science project isn't gummy, but it does have interesting properties of both solids and liquids. It normally behaves like a liquid or jelly, but if you squeeze it in your hand, it will seem like a solid. This is an easy project that takes just 10 to 15 minutes.

Simple Oobleck Ingredients

There's nothing complicated here, which is part of the charm of oobleck. The ingredients are inexpensive and non-toxic.

Water

Cornstarch

Food coloring (optional)

How to Make Oobleck in Your Kitchen

Mix 1 part water with 1.5 to 2 parts cornstarch. You may wish to start with one cup of water and one and a half cups of cornstarch, then work in more cornstarch if you want a more 'solid' oobleck. It will take about 10 minutes of mixing to get a nice homogeneous oobleck. Mix in a few drops of food coloring if you want colored oobleck.
