Cut the rainbow belts into strips measuring 1.5 inches (or slightly longer than a gummy bear) using scissors or a sharp knife, and set them aside.
Arrange the jello shot cups on a cookie sheet or chopping board.
Boil one cup of water on the stovetop or heat it in the microwave in a large bowl or measuring cup with a spout.
Whisk in the jello mix until fully dissolved, which should take about 2 minutes.
Stir in one cup of cold water (juice, alcohol, or a combination) until well-mixed.
Carefully fill each jello shot cup halfway (or with two tablespoons) to yield 20 jello shots. You can fill them higher if you prefer, but this will reduce the total number of shots.
Place the jello shots in the refrigerator to chill for 3-4 hours, or until they’re completely set.
Once set, assemble the cups by placing one gummy bear into a peach ring and resting it on top of the blue gelatin. If you’re using rainbow belts, lay a piece on top of the jello and add a gummy bear. Keep the shots chilled until you’re ready to serve.
Notes
Measure Accurately: For the best results use a measuring cup for the water and jello mix to ensure the correct proportions, which is key for optimal setting.
Stir Gently: When mixing the jello and water, stir gently to avoid creating bubbles, which can affect the appearance of your jello shots.
Chill the Cups: To make filling the jello shot cups easier, chill them in the refrigerator for about 10-15 minutes before pouring in the mixture.
Layering Techniques: If you decide to layer, pour the first layer and let it set until firm before adding the next to avoid color mixing. #Alternate a white layer, a red layer, and a blue layer for the fourth of July or other patriotic holidays.
Experiment with Add-ins: For extra flavor, consider adding fresh fruits or herbs. Muddled fruit can be mixed into the jello or placed at the bottom of the cups before pouring the jello mixture.
