Anybody else stuck inside? Here in St. Louis we got anywhere from 8-14″ of snow yesterday and the city is all but shut down today. If you are trapped in your home with your kids, you may be looking for something (easy) to do to mix things up. Feel like getting a little messy? Try out this experiment!
You will need:
cornstarch (Start with a cup or two)
food coloring (optional…I skipped it)
Pour cornstarch into the bowl. Let your kiddo play in it. Cornstarch has a really unique texture that is super silky smooth…if you’ve never felt it yourself, go for it! Even my little guy who’s a little bit sensitive to sensory stuff liked it!
Now it’s time to add water. Start pouring (about a 1/2 cup at a time) and use your hands to mix it with the cornstarch.
Now’s when the fun begins (and when Buddy wasn’t *quite* as interested in sticking his hands in the bowl…took a little coaxing.)
What’s so cool about that you say? Well, when you pick some up, it immediately turns liquid and runs from your hands.
But if you grab a hunk and keep it moving or roll it in your hands, it instantly turns solid. Crazy!!! Hard to get a picture of unless you have a third arm…which I do not.
See how it’s in a ball? Now watch what happens when I stop rolling it between my fingers.
There it goes…going, going,
If you are using a large enough bowl or pour it into a flat bottomed container you can smack it and watch it crack. So cool. And I’ve heard if you get it just right you can make it bounce but I wasn’t able to replicate that. Guess we’ll have to make it again! Happy snow day folks!
