Instructions

  1. Watch the SciShow’s constellations video on YouTube or use your own educational unit to help your students identify common constellations in the sky.
  2. Hand out black construction paper to your students. Have them map out their constellation in pencil.
  3. Now it’s time to light up the night! Pour the entire bottle of Elmer’s® Glow in the Dark Glue into the bowl..
  4. Add ½ tbsp. of baking soda and mix thoroughly. Then add 1 tbsp. of contact lens solution. Mix until solution gets thick and slime begins to form.
  5. Take out the slime and begin kneading it with both hands. If needed, add another ¼ tbsp. of contact lens solution to make the slime less sticky.
  6. Now, have students break off pieces of slime and place dots (aka stars) on their black paper until they have the entire constellation outlined.
  7. Turn out the lights and watch the entire classroom glow.

* Adult supervision is required; this project is not appropriate for children under the age of 3 years. Always wash your hands before
and after making and playing with slime. Warning: If large quantities of contact lens solution are accidentally ingested (greater than a tablespoon), get medical attention immediately.

* Some contact solution brands work better than others. Check out the Slime Tips section at elmers.com/slime for details.
