When the kids wanted to do a Ninja Turtle theme for school, I knew the 5 year old in particular would enjoy making Teenage Mutant Ninja Turtle Ooze.
This is similar to Bartholomew's Oobleck, if you are a Dr. Seuss fan.
1/2 cup corn starch
1/2 cup water
green food coloring
1/2 cup baking powder
(or any amount you wish to make, but use equal parts)
Spoon/spatula to stir
1. Mix several drops of green food coloring into the water.
2. Mix corn starch and water together in bowl until dissolved.
3. Add baking powder and watch it bubble and "ooze" for a bit.
4. Get slimy!
I let the boys do the measuring, pouring and stirring.
Here's where we added the baking powder and it started to "ooze" for us.
We did have to finish mixing it together so they could get started! One of the boys was apprehensive . . . for just a few seconds anyway!
The boys were intrigued with how it went from feeling thick and goopy to liquid-like as you moved your hands through it quickly or slowly.
This was a quick and easy sensory activity for a little bit of play, but of course it could easily turn into a science lesson as well. This was our kick-off activity for our Teenage Mutant Ninja Turtle unit study, and I wanted to keep it light and simple, so we left it as a "fun" activity. There's more TMNT coming, so be on the lookout!
