Ectoplasm Slime Recipe: Slippery Fun for Halloween Venn Crawford

Halloween is for all things spooky and creepy, and so slime fits right into the October aesthetic. In the spirit of all things ghoulish, I’ve created an ectoplasm slime recipe for you to try. All you need is borax, Elmer’s glue, water, and food coloring (you can find borax with laundry supplies at most stores).

Multicolor Slime Misadventures

Originally, I wanted to make a black, orange, and purple slime. When I made the purple, I realized it would take far too much food coloring to do black. So, I decided to make orange and purple.

To make the base for slime like this (which isn’t clear like my ectoplasm), I mixed a half cup of water with a bottle of white Elmer’s glue and added five drops of yellow and two drops red food coloring.

Water and glue form the base for slime.

To finish it (which I sadly don’t have pictures of), I mixed a cup of warm water with a teaspoon of borax and stirred it into my glue mixture. The slime formed much faster than I thought it would. I made a batch of purple as well and mixed them only a little so that the colors would stay separate.

Unfortunately, when I got my slime out of the fridge this morning, the colors had muddied together and turned the slime an ugly mottled grey. My ectoplasm slime recipe, however, was a success.

Ectoplasm Slime

When I first tried to make the ectoplasm slime, I used only clear glue, and it ended up looking like flubber. No really, see for yourself:

Clear slime turned out to be too clear for ectoplasm.

It almost looks like a bunch of melted jolly ranchers.

The first try at ectoplasm slime looked like flubber.

The second time around I added a tiny bit of white glue as well, and it ended up much better. It reminds me of Ghostbusters! This is definitely my favorite of the slimes I made.

This ectoplasm slime is my favorite halloween slime recipe.

The recipes I’ve provided are basic, but you can upgrade your slime by adding glitter or polystyrene beads to give it extra texture. If you want to add glitter, I’d recommend using a color that contrasts with what you already have, such as putting black glitter into the orange slime. Make sure to add the glitter or beads after the food coloring and before the borax.

Ectoplasm Slime Recipe

Ingredients
1 bottle clear Elmer’s glue
1 tsp white Elmer’s glue
1 ½ cups warm water
1 tsp borax
Green and yellow food coloring
2 bowls

  1. Fill your first bowl with ½ cup of water and a bottle of clear Elmer’s glue. Add in about a teaspoon of white Elmer’s glue. Once the mixture is even and milky-looking, add 1 drop of green food coloring and 2-3 drops of yellow. Stir until the color is even throughout.
  2. In your second bowl, add 1 cup of warm water and then dissolve a teaspoon of borax in it. Make sure the water is warm – the borax won’t dissolve as well in cold water.
  3. Once the borax is dissolved, pour into the bowl with the glue mixture. Stir and watch as the slime congeals. I find that stirring with a chopstick or skewer works best, as they’re easy to clean. The slime should catch onto your stick. Stir for about 2 minutes.
  4. Pick up your slime and pour out any excess liquid in the bowl. Your ectoplasm slime is done! To store, put in a ziplock or other container and keep in the fridge.

If you’d like to try your hand at making the opaque orange slime, the recipe is very similar. Use the ectoplasm slime recipe, but instead of clear glue, use white Elmer’s glue. For the food coloring, add 5 drops yellow and 2 drops of red.
