Ectoplasm Slime Materials

You only need two ingredients to make the basic slime, though you can add coloring to make the slime any combination of colors that you like or to make it glow in the dark.
  • 1 teaspoon soluble fiber (e.g., Metamucil psyllium fiber)
  • 8 ounces (1 cup) water
  • food coloring (optional)
  • glow paint or pigment (optional)

Make Your Ectoplasm

  1. Pour the water and fiber into a large microwave-safe bowl.

     

  2. Microwave the ectoplasm on high power for 3 minutes.

     

  3. Stir the ectoplasm. Return it to the microwave and heat it for another 3 minutes.

     

  4. Stir the ectoplasm and check its consistency. If you want drier ectoplasm, microwave the ectoplasm another minute or two. Continue checking the ectoplasm and microwaving it until you achieve the desired consistency.

     

  5. Add a drop of food coloring and/or some glow paint, if desired. You'll get an interesting effect if you incompletely mix the coloring into the ectoplasm, such as multicolored ectoplasm or ectoplasm slime with glowing streaks.

     

  6. Store the ectoplasm in a sealed baggie to prevent dehydration. The slime will last for a week or longer, as long as you keep it from drying out.
