OOBLECK. Such a fun word to say, right? I use to make this when I worked in daycare. It’s such a fun science experiment for kids 2 years old and up. The best part is it’s only 2 ingredients and you are bound to have them in your house already.
So What Is Oobleck?
Without getting into the nitty gritty, Oobleck is simply a solid AND a liquid. Depending on how you use it and the amount of pressure you put on it, it will act as a liquid and a solid. Pretty cool huh? I honestly can’t tell you why it works this way, but it’s so fun to play with, it’s easy to make, and the clean up is fairly easy. Win-win-win!
- 2 cups cornstarch
- 1 cup water
Mix the cornstarch and water into a bowl. Mix until your Oobleck is formed. That’s it. I added a bit more cornstarch, but the above ratios are a good place to start. I got the ingredients ratio from here.
Tip: If you find the Oobleck is too watery, add more cornstarch. If it’s not drippy add a tad more water.
We used some of Roman and Mallory’s toy kitchen utensils to play with it. We watched it drip through our fingers and we even made it into a ball. If you tap it quickly with your finger or a spoon it feels hard. If you gently put a spoon in it scoops like a liquid.
I hope you have as much fun with this as my kids did! Let me know what you think. And hit that share button to help your friends have some rainy day fun with their kids!
