Sensory Slime

Making Slime – smooth, gooey substance – is a fun, educational activity that teaches the concept chemical reactions when different substances are mixed together. This activity isn’t right for every individual with autism e.g. individuals who might eat the mixture or individuals whose tactile defensiveness will not tolerate sensory slime. But many individuals with autism enjoy the unique texture of this slime. Making slime gives folks a chance to follow written instructions, measure ingredients, and learn about chemical reactions.

So, here’s the recipe for Slime. If your friend with autism is able to read, copy the recipe and let them collect the three ingredients and necessary utensils. If they are not able to read, read the ingredients and let your friend collect the supplies. You may need to pair your verbal instructions with a visual cue i.e. picture, sign, or actual item. Remember to let your friend with autism make their own slime. Only lend a helping hand when absolutely necessary.

First, gather these ingredients: ½ cup or 4 ounces white Elmer’s glue, ½ cup water, 1 teaspoon borax powder, and 1 cup water.

Now, follow these easy steps.
1. Pour the glue into the a glass bowl or 2 cup glass measuring cup.
2. Stir ½ cup water into glue. Note: The resulting slime will be opaque white. If you want a different color, add a few drops of food coloring to the glue mixture.
4. In a separate, bigger glass bowl or 4 cup glass measuring cup, stir 1 teaspoon of borax powder into one cup of water.
5. Slowly stir the glue mixture into the bowl of borax solution.
6. Place the slime that forms into your hands and knead until it feels dry. (Don’t worry about the excess water remaining in the bowl.)
7. The more the slime is played with, the firmer and less sticky it will become.
8. Have fun!
NOTE: Store your slime in a zip-lock bag in the frig so it doesn’t grow mold. It is best to supervise folks so they don’t eat the slime. Although it is not toxic, it is not particularly good for you. But many people enjoy the smooth, soothing texture of this homemade slime.
