It’s Vampire season! For Slime that is. Kids will love making slime. It’s jiggly, edible, glow-in-the-dark Vampire Slime.
It’s perfect for play or adding some gore to pumpkins, costumes, and more.
This glow-in-the-dark vampire slime offers all the creepy to make it fun for Halloween, but not scary, so little ones can take part in the fun.
It’s simple to make and creates gooey slime kids love to play with.
Try mixing some up for your Halloween get-together, a package for trick-or-treaters, or just for an afternoon of entertainment.
It’s easy to make with just three ingredients and a microwave.
Shine a black light on it and it glows blue-white.
It’s also edible, though I’m not sure why you would want to eat it, it’s safe to use around the mouth.
My kids will attest that the more gross you can make the slime, the better it is.
They like the reaction.
And this Vampire Slime does not disappoint.
Made with Metamucil Fiber supplement powder it’s edible and the powder gives it an interesting, not messy, consistency.
Please make sure the main ingredient in your fiber supplement powder is psyllium husk.
In science terms, psyllium husk is the active ingredient, that when mixed with water and heated, it thickens.
The more water that is absorbed, the more flubber the consistency.
And while this slime tests safe as “edible”, please do not encourage children to eat it.
This slime recipe uses “edible” ingredients rather than the Borax, contact cleaner, and glue.
Here’s how:
Thoroughly wash your hands before and after making and playing with slime. Do not substitute any ingredients in this slime recipe.
Edible Glow-in-the-Dark Vampire Slime Ingredients:
1 tsp Metamucil
1 cup diet tonic water
2-3 drops red food coloring
Edible Glow-in-the-Dark Vampire Slime Directions:
Add the Metamucil to the tonic water in a small microwavable bowl.
Add the food coloring. It will get darker as it processes, so keep this in mind.
Heat mixture in the microwave until it boils (about 1-4 minutes; microwaves vary)
When the mixture boils, stir the mixture with stick or spoon.
Cook the mixture for another 1-2 minutes.
Stir it.
Repeat cooking and stirring another 4 to 5 times, until it forms a gelatinous consistency.
Remove from microwave–container will be HOT!
Allow the mixture to cool.
Store in an airtight container.
Note: The slime is not sticky, however, the red dye may stain some surfaces and fabrics.
We hope you enjoy this jiggly, edible, glow-in-the-dark Vampire Blood Slime.
