This is one of my most favourite activities in class, loved by parents as much as the kids!
Oobleck is such a simple sensory activity to make and it is also one of the best things for improving muscles in fingers, hands and arms because of the texture.
If you haven’t felt oobleck before, it’s an awesome combination between a liquid and a solid, know as a non-Newtonian fluid (if you like proper names!)
The great thing about this activity is it’s completely taste safe for little ones!
Things to do with your oobleck:
- Use a scoop to pick it up and watch it drip
- Put some in a strainer and watch it drizzle through
- Grab it with your hands and hold it as long as you can
- Put your feet in an give it a squash!
- Make a fountain using stacked cups or bowls
- With your older kids make deep oobleck and test different objects to see if they sink or sit on top
What you need:
- Corn starch/flour
- Food coloring (optional)
- A mixing bowl
- A wooden spoon
- A tray
How to make it:
Getting the right consistency can be tricky, so it’s all about experimenting! Your oobleck should turn hard when you try and grab it but run off your hands when you release your grip on it!
- Mix 2 drops of food coloring with 2 cups of water.
- In your bowl put 4 cups of cornstarch and then add the water and mix really well. You will find that the mixture looks liquid but is really hard to stir, that’s perfect!
- If the oobleck is to runny just add a bit more corn starch, if it’s too stiff just add a bit more water!
- Oobleck will dry out after playing with it, if you want to refresh it just add a bit of water.
I would definitely recommend this as an outdoor activity, or if you are indoors pop some towels on the floor!
