What couldn't Halloween costume or party benefit from some blood slime? This particular slime is also edible, non-sticky and glows blue-white under a black light. It's easy to make!
Glowing Blood Slime Materials
- 1 teaspoon soluble fiber (e.g., Metamucil)
- 8 ounces (1 cup) diet tonic water
- red food coloring
Make the Slime!
- Stir the fiber into the tonic water.
- Add a drop or two of food coloring. The slime gets darker during preparation, so don't add too much food coloring.
- Heat the liquid in a microwave-safe container until it boils. Depending on your microwave power this may be anywhere from 1-4 minutes. When the mixture boils, pause the microwave and stir the slime.
- Cook the microwave another 1-2 minutes. Stir it.
- Repeat the cooking/stirring cycle a total of 4-5 times, until the slime develops a gelatinous consistency. Carefully remove the slime from the microwave. The container will be very hot!
- Let the slime cool before you handle it. You can play with it, decorate with it, or even eat it. No matter what color you made your slime, it will glow blue-white under a black light or ultraviolet light. The glow is fluorescence from the quinine in the tonic water.
- Store your slime in a sealed bowl or plastic bag. If you are just decorating with it, it's fine at room temperature, but if you plan on putting the slime in your mouth, it's a good idea to refrigerate leftovers.
- While the slime won't stick to most surfaces, the food coloring will cause it to stain fabrics and skin. Clean up slime with soap and water. Your favorite stain remover will take out the food coloring.
