Making slime is all the craze! Using just a few ingredients you can make a hands-on experience for your kids. Slime reminds me of the days of Silly Putty. I remember saving money to buy the Silly Putty in the egg capsule. It you’re too young to remember, we used to take the Silly Putty and place on a newspaper to get the imprint. Those were the days that a small innovation was exciting.
As a preschool owner/teacher, I am always looking for hands-on learning, especially if it enhances science, motor skills and interactive fun. Making slime does all of these. The science is letting the children see the wonder of pouring the borax solution into the glue/water mix and watch it immediately form into a playable dough. The kids loved it. It’s also a great hands-on and fine motor development activity. After I made the slime, the kids played with it for the rest of the activity center time. I ended up making more as all the students wanted to play with it.
The two main ingredients (glue and borax) are NOT edible. See below for the borax ingredients. This is an activity that needs constant supervision if children are under the age for five. I say this for a few reasons. The main one is making sure that the slime is not tasted or eaten (you would be surprised how many children try to taste new things). The other reasons is that the children may take the slime and put it somewhere like on the carpet or in places that will be difficult to clean.
I always have my students wash their hands after playing with slime.

- In a large bowl, mix 1 cup water and 1 cup Elmer’s glue. Add drops of food coloring.
- Slowly pour borax liquid in the center of the glue mixture and stir. Continue stirring until you have slime. If you want the slime to be thicker, you can add more glue and stir.
- After play, store in air-tight container. you do not have to refrigerate.
The kids had fun making handprints and then seeing them disappear.
So the most menacing warnings about substances related to borax (including boric acid) relate the skin contact, eye contact or when it was “given ..by mouth at high doses.”
You know what else can irritate the eyes and skin and even cause digestive problems at high doses? Vinegar, cinnamon, tumeric, cayenne pepper too. That doesn’t mean that those things aren’t safe but just that they must be used safely. Borax is extremely alkaline, which makes it irritating when used undiluted.
Makes sense not to use any form: borax, sodium borate or boric acid as an eye wash, skin scrub or drink it, but it doesn’t answer the question about if occasional indirect contact is safe.
