Option One: Juniors & Primaries


  • White school glue, 2 ounces per child
  • Food coloring
  • Baking soda, 1/4 teaspoon per child
  • Saline solution, 1 1/2 teaspoon per child
  • 9 ounce clear plastic cups, 1 per child
  • Plastic spoons, 1 per child
  • Snack-size zippered baggies, 1 per child

Tools and Basic Supplies

  • Measuring cup
  • Measuring spoons (1/4 teaspoon and 1/2 teaspoon)
  • Permanent markers


  1. Right before the kids arrive (not the day before or it will dry out), measure 2 ounces of glue into each cup, 1 cup per child.
  2. Pour baking soda into bowls for each table.

Class Time Directions

  1. Remind the kids that they may hear that slime + time = man. In other words, that we evolved. But we did not start as slime. Jesus, the Creator, made us in his image (Genesis 1:26–27), and we are fearfully and wonderfully made (Psalm 139:14).
  2. Have each student write his name on a zippered baggie with a permanent marker.
  3. Add two or three drops of food coloring to your cup of glue. Then mix it with a spoon.
  4. Add 1/4 teaspoon of baking soda and mix it well.
  5. Slowly stir in 1 1/2 teaspoon of saline solution. Stir until it firms up.
  6. If still too slimy, add just a tiny bit more saline solution. If you add too much, the slime will lose some of its elasticity.
  7. Remove your slime from the cup and knead it with your fingers. Then place it in the zippered baggie to take home.

Tip Corner

  • This is always a huge, huge hit with kids! They love slime.
  • Clear school glue works well, too, and gives the slime a translucent appearance.
  • Saline solution can be found at drug stores and discount stores in the eye care products section.
  • Avoid foam cups. Slime will stick to the sides and bottom, making it more difficult to remove.
  • Remind the kids not to play with this on carpet.
