How To Make Goop
Goop is one of my favorite sensory activities for babies as well as toddlers, preschoolers and elementary students. You’ll be surprised by what cornstarch and water can create. Children can’t seem to get enough of playing with it. Trust me, even the adults can’t keep their hands off!
- 2 cups of cornstarch
- 1 cup of water
How to make oobleck: The ratio is approximately 2 to 1. How much you make will be determined by your sensory table size. Start with 2 cups of cornstarch and then mix in the water. If you can’t grasp it into a ball like substance add another tablespoon of cornstarch. If it isn’t liquid enough.. add some water.
Sometimes we put the oobleck on a tray, sometimes on the large storage tote and other times straight up on a plastic table if there is a little lip there to keep everything from falling.

Today we had some very very messy fun! We mixed cornstarch and water (which is known as Maizena in some parts of the world) and mixed it to create a fun and unique texture that is sure to keep kids (and adults) busy!
For those of you that attempt this with young kids please keep your eye on them at all times… buttons can be a chocking hazard…. I chose to use very large buttons because of this but as you can see, I had a very close eye on my 1 year old.
D would run his finger through the mixture and pick it up and watch the liquid ooze down his fingers… This mixture looks a little hard but when you touch it.. it melts.. its pretty cool if i do say so myself!
While this is one of the messiest activities that we have done I can say in all honesty it was also one of the best and most fun activities ever!
