Sensory Slime Science
Slime is made when boron mixes with the polymer chains in the glue, creating strong, but flexible bonds between the molecules. There are so many fun tweaks you can make to a basic slime recipe, like my kid’s favorite, fluffy slime!
Since this slime does contain borax, if you have a sensitivity to it, you may want to try our baking soda slime instead.

Step-by-Step Directions to Make the Rainbow Sensory Slime Recipe
Let your preschooler have some sensory fun with this contrasting textures sensory slime recipe!

Before playing, mix up the slime. You can have your kids help with this, or if you don’t want the trouble, do it ahead of time.
We typically use a ratio of one part glue, one part water, and one part starch for all of our stretchy slimes.
We’ve tried other slime recipes, but this is our favorite because it stretches easily without breaking.
In this particular case, we used 1/2 a cup of water, starch, and glue. Mix the water, glue and food coloring together before adding the starch or you’ll end up with a huge mess.

After mixing the slime, let it rest about five minutes before adding the beads.
Add a handful of beads (or you can use a specific number if you’re working on counting to 20 or 100) and mix them in the slime.
Give the slime to your kids on a large play tray (we love this one).

Let them play with the slime and remove the beads from the slime. As they try to remove the beads, the slime with stretch and provide tons of sensory fun.
