We used some standard gum drop molds. Plastic candy molds and shaped ice cube trays woork too (small shapes work best).Cooking spray 1 3-oz. package powdered Jell-O, any flavor. This also depends on what color you want you LED's to be. We used Jolly Rancher Green Apple Flavor.7 packets gelatin, unflavored 1/2 cup TONIC WATERSmall saucepan Small whisk Wooden spoonUseable Options:Food Syringe3D Printer (we used this to create the LED leads and printed in PLA which is a corn based plastic) (you could easily use 2 plastic food picks or colored toothpicks)Blacklight bulb
You can use your 3D Printer to make the leads. Here is the .STL file you will need to make them from Thingiverse.If using plastic picks or colored tooth picks skip this step.
1. Spray plastic candy molds generously with cooking spray. Set molds aside.2. Use a fork or small whisk to combine powdered Jell-O and gelatin in a saucepan. With a wooden spoon, stir in tonic water. Don’t worry if it isn’t smooth.3. Stir mixture constantly over medium heat with the wooden spoon until the powder is completely dissolved and you feel no more grit when you stir. Do not allow mixture to heat to a boil.4. When the powder is completely dissolved, remove the pot from the heat and pour the mixture carefully into molds, being careful that the mixture does not overflow the molds. If you have a food syringe you can utilize it now.
Allow to cool completely (about 10 minutes in refrigerator or 30 hour at room temperature) and insert your leads. You might find it easier to monitor the cooling and insert your leads earlier.
Unmold and enjoy! If you have a blacklight set up make them glow!
