Step 1: Materials:

  • Decorative glass jar with lid
  • Polly Plastics Moldable Plastic and Color Pellet Kit (Thermo Plastic Pellets)
  • Glass bowl for water
  • Parchment paper
  • Measuring spoons
  • Metal spoon
  • Toothpick
  • Paintable white silicone and caulking gun
  • LED Push-Button Tap Light
  • Adirondack Alcohol Inks (Sunshine Yellow, Sunset Orange, Purple Twilight, Caramel, Latte and Ginger)
  • Small knife or small metal spatula
  • Old paintbrush

Step 2: Making Your Parisitic Worms in a Jar Halloween Decoration

Step 1. Heat water in a kettle or microwave to at least 150 degrees F. Follow the directions enclosed with the thermo plastic. Add 1 Tbs of the plastic pellets to the hot water.

Step 2. The plastic pellets will start to turn clear and clump together. Let the plastic sit in the hot water for approximately 2 min. Use a metal spoon to clump the metal plastic pellets together and remove them carefully from the water. It’s important to use the metal spoon, since the plastic will bond to a plastic spoon.

Step 3. Knead the plastic together between your fingers. If the plastic starts to get too stiff, just put it back in the hot water and let it soften up again. You might need to periodically reheat the water.

Step 4. Shape the plastic like a worm, flattening one end, to create a large open mouth.

Step 5. As the plastic starts to harden, use the small metal tool or knife to press lines around the body of the worm, this will create a textured effect on the worm. Let the plastic cool. As it cools, it will change from clear to opaque white.

Step 6. Drop some sunset orange alcohol ink on the worm. The ink will spread and fill in all of the crevices and imperfections in the plastic.

Step 7. You can use and old brush to spread the ink around the plastic. The ink dries very quickly, so it might not spread too far.

Step 8. Add more ink to the worm, switching colors between ginger, latte and caramel.

Step 9. Color the inside of the mouth with purple twilight ink.

Step 10. Line the outside of the mouth with silicone.

Step 11. Using the toothpick, gently pull the silicone toward the mouth to create teeth. Let the silicone dry for at least 30 min, depending on the instructions provided by the manufacturer. Once dry, the silicone is 100% waterproof.

Step 12. Use ginger ink to blend the edges of the silicone with the plastic body of the worm.

Step 13. Repeat the steps above to create more worms of different shapes and sizes that will fill your jar.

Step 14. Place the worms in your jar and fill with water.

Step 15. Add a few drops of yellow ink to the water. This will help make the specimens look like they are floating in formaldehyde.

Step 16. The worms look pretty gross on their own, however you can place the jar on an LED bottom light to illuminate them.

Step 3: Save These Specimens to Your Halloween DIY Boards.
