How to Make Kool-Aid Oobleck
- In a large mixing bowl, combine the corn starch, water, and kool-aid. Let your child get their hands in the mixture and start incorporating the mixture.
- The mixture should be thick enough to be pressed into a ball, but the mixture will turn into a liquid as soon as you stop pushing on it. If the mixture is too thick, add a few tablespoons of water. If the mixture is too thin, add a few tablespoons of corn starch.
- Allow your child to experiment with how the oobleck will behave with different amounts of pressure.
FAQs
You need to store it in an airtight container; if I use up all the corn starch, I like to keep it right in that container. It will start to separate after a few hours, but you can just stir it up to combine it again. This will last for about two weeks in the airtight container.
Oobleck is a non-Newtonian fluid. It isn’t a liquid or a solid! If you go on youtube, you can see videos of people filling up a swimming pool with it then running across it, but they will start to sink if they slow down.
It becomes easier to clean up as it dries because then you can just sweep up and corn starch clumps on the tables and floor. I highly recommend having this as an outside activity, so you can have a super easy clean-up of just hosing it away. Just make sure you don’t pour this mixture down the drain; it will clog them.
