How make oobleck
Oobleck is a non-Newtonian substance that is awesome for kids to have sensory play with.
Yield: 1 sensory bin
Equipment
- Spoon
- Large mixing bowl
- Sensory bin (I use a 28 quart storage container)
Materials
- 1 cup cornstarch
- 1/2 cup water (dyed with food coloring if desired)
Instructions
- In a bowl, combine cornstarch and water. If using food coloring, add food coloring to water before combining with cornstarch.
- Mix with a spoon to fully incorporate. Substance will progressively be harder to stir as cornstarch and water combine. When pushes with the spoon, the oobleck should break like a solid and also ooze like a liquid.
- Pour into a sensory bin or water table. Add in kitchen utensils for imaginary play.
Notes
- Recipe can be duplicated. Follow the ratio of 2:1 cornstarch to water.
- Typically use 1 cup cornstrach + 1/2 water per child playing.
- Food coloring is optional, but should be added to the water first and mixed.
- Cornstarch containers have a warning to not consume raw. Please make good judgements for your child
- To clean up, either let oobleck dry and scrape into garbage or flood with water using hose, sink or bathtub to dilute the cornstarch mixture back to a full liquid.
