Water and Starch equals Oobleck Slime. Easy science experiment with 2 Ingredients

Water and Starch Combination

Oobleck slime science experiment is for all ages. Do you have your children or grandchildren or a child visitor with you today, take starch (tapioca, potato, or corn) and mix with water. This water and starch experiment is fun and easy to make and clean afterwards. Moreover, Dr. Seuss wrote about it in his book: “Bartholomew and the Oobleck

Why Dr. Seuss? 

Bartholomew and the Oobleck is a 1949 book by Dr. Seuss. It follows the adventures of a young boy named Bartholomew Cubbins, who must rescue his kingdom from a sticky green substance called “oobleck.”

Let’s explore together what happens when we add water and starch together? 

Starch and water make suspension. When you squeeze the mixture it feels – solid because its molecules line up. But it looks and acts like a liquid when no one is pressing on it because the molecules relaxed.

You need:

  • 1/8 cup of water
  • 1/4 cup of tapioca starch (or any other starch)
  • Mix and Play!

Observe it at home and see what changes when you add more or less water or warm up the mixture?
