To make oobleck, you only need two basic ingredients: cornstarch and water. Here is a simple step-by-step method:
- Measure about 1.5 to 2 cups of cornstarch and place it in a large mixing bowl.
- Slowly add about 1 cup of water to the cornstarch. If you want colored oobleck, add a few drops of food coloring to the water before mixing.
- Stir the mixture with a spoon at first, then use your hands to mix thoroughly. The goal is to achieve a consistency where the mixture behaves like a thick liquid but feels solid when you apply pressure.
- Adjust the texture by adding more cornstarch if it is too runny or more water if it is too dry. Mix well after each addition.
- When done, the oobleck should feel like a solid when squeezed but flow like a liquid when left alone.
Tips:
- Oobleck is messy, so play on a covered surface or outdoors.
- It can dry out; add a few drops of water to reactivate it.
- To clean up, let oobleck dry and then scrape it into the bin; wipe surfaces with a damp cloth.
