CLARKSBURG, W.Va. – What’s Halloween without a Jack-O-Lantern? In this science experiment, we take our friend Jack and make him ooze something a little something scary.

Here’s what you need:

  • Gloves or safety glasses (optional)
  • Jack-0-Lantern (The bigger the cut-outs, the better the effect)
  • 1 cup 40 Volume Hydrogen Peroxide (This can be found at beauty stores)
  • Measuring cup
  • Cylinder (We cut the top off a plastic water bottle)
  • 2 TBS Dish Soap (Any brand/color)
  • 4 drops food coloring for fun
  • 6 TBS Warm Water
  • 2 packages of Instant Yeast
  • Fork

Step-by-step instructions

  1. Place your Jack-O-Lantern on a level surface and insert the cylinder
  2. Have an adult pour 1 cup of Hydrogen Peroxide inside the cylinder
  3. Add dish soap, a couple squirts from the bottle is good
  4. Add food coloring (Any color, we did red)
  5. In a separate bowl or cup, add warm water to yeast and stir with a fork for 30 seconds
  6. Add yeast mixture and back up!
  7. Elephant toothpaste will pop out the top, ooze out the front – or both if you’re lucky!

This is a Halloween version of an experiment called “Elephant Toothpaste.”
