What You’ll Need
Craft tray (optional)
What to Do
- Pour 1 cup of water into your mixing bowl.
- Mix in your food coloring (we used liquid watercolors).
- Add in 2 cups of cornstarch and mix well. Depending on the consistency, you may need to add additional cornstarch. At first the kids weren’t sure they wanted to put their hands in the oobleck but we finally convinced them to start with just a finger. They were hooked after that!
You’ll want your oobleck to be somewhat thick but not to the point that it doesn’t turn into a liquid when held in an open hand.
Now try squeezing the oobleck. Does it thicken up into a ball?
We all had a blast and couldn’t help but get in on the fun with the kids.
The kids then decided to add in a few objects to the mix to test if they would sink or stay on top.
The kids played with this for HOURS!Click To Tweet The kids played with this for HOURS, especially the older one. Miss 3 played with it for about an hour, while miss 6 would have played with it all night long if we had let her.
Now I know what you’re thinking. Oh woah, no, that looks too messy, I can’t do that! Trust us though, if you place a plastic craft tray under the bowl (and maybe even some newspaper under that, you will greatly contain most if not all of the mess. We also like to put a wipeable tablecloth under our work area (placed on the floor) as well, just in case any falls down. We did have some fall on the carpet but it cleaned up surprisingly easy. Simply wait for it to dry and then wipe it up with a damp washcloth. You can clean the table the same way- once the oobleck dries, it becomes crumbly and is very easy to rub right off the surface it is on.
