This is a great activity to do at home with your littles. We had so much fun making Oobleck that I always make sure I have cornstarch in the cupboard for those afternoons when you’re stuck indoors. It also makes a great science project, because Oobleck acts as both liquid and solid.
1 cup water
1.5 to 2 cups cornstarch
Small amount of food coloring or paint (optional)
- Start with the water in a bowl and add small amounts of the cornstarch.
- Use your hands to mix it until it becomes gooey.
- When the Oobleck is just right, slowly add the food coloring or paint – I added neon paint for a bright affect.
- Now it’s time to play!
Ways to have fun with Oobleck
- Squeeze it and watch it ooze through your fingers.
- Drag your fingers through it and watch it retract back into shape.
- Roll it into a ball and the pressure will turn it solid and then watch as it melts when you put it down.
There are lots of different recipes for making Oobleck that you can experiment with. Why not try adding glue for a different texture, or even shaving cream to make it fluffy. We even added toy dinosaurs to the mix:
The name Oobleck comes from “Bartholomew and the Oobleck,” by Dr. Seuss, where a sticky liquid falls from the sky as a result of the king becoming bored with normal weather. Open up their imaginations by reading the story and then making your own sticky liquid.
