How to Make Rainbow Slime
What you will need to make your Rainbow Slime is in this picture below. However, I have it displayed in a recipe list form to print out towards the bottom of the page. Have Fun!

How to Make Slime with Contact Solution
Supplies needed:
- 6 (6 ounce) bottles clear Elmer’s Glue (one for each color) or 4 ½ cups clear glue divided into ¾ cup increments
- About ½ cup warm water, for each batch
- ½ teaspoon baking soda, for each batch
- 1 tablespoon contact lens solution (containing boric acid), for each batch
- Food coloring, in red, blue, yellow, and green
- Toys or foil confetti (if desired)
To make the colors in this project, we used:
- Red – 10 drops red food coloring
- Orange – 5 drops yellow food coloring and 3 drops red food coloring
- Yellow – 10 drops yellow food coloring
- Green – 10 drops green food coloring
- Blue – 10 drops blue food coloring
- Purple – 5 drops red food coloring and 4 drops blue food coloring

You will be making six separate batches of slime with one in each color. (all the colors of the rainbow!)
The first thing you need to do is empty the glue into a large bowl.

Fill the empty glue bottle about ⅓ full with warm water (about ¼ cup) and seal with the lid. Shake well to combine the remaining glue with the water. Pour into bowl with glue and stir to combine.
Next, add the baking soda to the glue and stir to mix thoroughly.

If you are adding additional glitter, confetti, or food coloring, stir it into the glue mixture and mix until added well.

How to Make Rainbow Slime Without Borax
Add in the contact lens solution to the glue mixture and stir well. (Note: regular glue will require less contact lens solution than glitter glue. Add the contact lens solution slowly, mixing between additions, and add only enough to bring the glue together into a soft ball.)

Remove the slime from the bowl allowing any excess liquid to remain in the bowl.
The slime will be sticky.
Begin to play with the slime, kneading it as you would bread dough, to bring the slime together. The slime is ready when no longer sticky.

Best if stored in an airtight container in the refrigerator when not in use.
