In Dr. Seuss’s classic Bartholomew and the Oobleck, oobleck is a green gluey slime that gums up the kingdom.
While our recipe won’t be quite as invasive as Dr. Seuss’s variety, it will still provide hours of entertainment and giggles for your children this summer.
Here’s how to make it!
- corn starch
- food coloring (optional)
1. Mix 1 cup water with 1.5 to 2 cups cornstarch. You may want to start with 1 cup of water and 1.5 cups of cornstarch, then gradually work in more cornstarch to achieve a thicker oobleck. You can begin mixing with a spoon, but you’ll probably switch to using your hands after a bit to get a more homogeneous result…plus, it’s more fun! Mix for about 10 minutes.
2. Mix in a couple drops of food color if you want dyed oobleck. And then enjoy your gooey goo!
The Chemistry Tie-In:
Oobleck is neither a true solid nor a true liquid. It is a type of non-Newtonian fluid called a dilatant.
The Literary Tie-In:
Read the Dr. Seuss original, of course!
