Corn Starch Goo

Years and years ago, our Bright Beginnings Lady came by all excited because she had a great learning activity. It was goo! Something about fine motor blah blah science blah blah blah.

By ‘great’, she meant ridiculously messy. By ‘learning activity’ she meant… ridiculously messy. We had this crap all over everything for weeks.

I swore we would never do goo again.

My kids forgot all about the goo, and I eventually threw away the blanket that had been washed 14 times and was still sticky. When we went to the Star Power Rally, last month, my kids and goo were re-acquainted in the Activity Tent. But this time, it was different. I asked for the recipe, and it was just corn starch and water. Blah blah something about a polymer blah blah fine motor. I have no idea what our Bright Beginnings Lady put in the original goo, but I was willing to give it another chance.

It’s super easy, but here is a video from Steve Spangler Science for you folks who like stuff like that:

I laid down our ‘craft’ table cloth, gave each kid a little bin, and let them go to town.  The texture is fun and feels like plastic, but it ‘melts’ when you try and hold it. We used about 1/2 box of corn starch and 3/4 of a cup of water, but it’s fun to let the kids add the water a little at a time so they can see how it changes.

They also decided they wanted to add food coloring too, which was a cool idea.

After a quick hose down, everyone and everything was clean.  I have another box of corn starch stashed away for a rainy (or 90 degree) day, too!

  1. Ooh! This goo sounds pretty great! And not half as messy as the other you described! Will have to save this for a rainy day activity this summer!

    It’s a good one; and the best thing is you just wash it all down the sink after you’re done :)


  2. We call it goop and have to make it at least once every summer. The boys usually bury superheroes and other toys in it :)

    Love it :)


  3. When I was in college we read the Dr Seuss book about Oobleck…and the science teacher made this for us in green food coloring. It was a fun way to tie literature with science….and spend a class doing a science experiment that was super fun!

    Wow! That never would have occurred to me; maybe next time if I am on my game!



  1. […] Corn Starch Goo: Big Binder – Have you ever made goo? No? What? Why? It’s so fun and SO EASY to do. A great time filler for rainy day. Or, in the case of HOTlanta, a day that is too hot to go outside. […]
