When we think of slime, we think of a super-fun gooey experience. But with the help of Ziploc® brand bags, we can create an awesome rainbow project that lets us enjoy slime and learn at the same time! In this experiment, we make slime in the three primary colors (red, yellow, and blue) and layer them up to produce secondary colors (orange, purple, and green).

When you overlap your bags, you can see the two primary colors blend together to form a new color. These are secondary colors. Try creating all three!
red + blue = purple
blue + yellow = green
yellow + red = orange
If you want to take the colors a step further, repeat the activity to create slime in each of the secondary colors and place them in their own
Ziploc® brand bag. Now try mixing and matching the primary and secondary colors with one another. Overlap these bags and see what new colors you can create!
MATERIALS
- 3 glasses
- 3 craft sticks
- Food coloring (red, yellow, blue)
- 1 ½ cups clear non-toxic glue (1/2 per color)
- ¾ cup water (1/4 cup per color)
- 1 ½ teaspoons baking soda (1/2 teaspoon per color)
- 3 tablespoons contact lens solution (1 tablespoon per color)
STEPS
- 1 Gather your materials.
- 2 For each color of slime, place an open Ziploc® brand sandwich bags over the mouth of a glass. Add a ½ cup of clear non-toxic glue to each bag (avoid filling the bag beyond half its size)
- 3 Add a ¼ cup of water to each bag, then mix the glue and water together with a craft stick
- 4 Add in 1 to 2 drops of food coloring to each glass. Stir the mixture until the color has evenly dispersed. To make red, add 2 drops of coloring. To make yellow, add 1 drop of coloring. To make blue, add 2 drops of coloring.
- 5 Add a ½ teaspoon of baking soda to each glass and stir the mixture until it has dissolved.
- 6 Add 1 tablespoon of contact solution to each color.
- 7 Stir each mixture. You’ll see and feel the slime start to come together. It will become less sticky and more slime-like!
- 8 Carefully remove the bags from the glasses and seal them. You should now have 3 separate bags filled with red, yellow, and blue slime. Overlap two bags at a time. What colors can you create?
