How to make Glow in the Dark Jello Cups

Creating fun and exciting treats for gatherings can be an enjoyable experience, especially when you want to wow your guests with something unique and playful. Glow in the Dark Jello Cups are perfect for parties, especially during Halloween or glow-themed events. Here’s how you can make this delightful and entertaining dessert.

Ingredients

Jello (any color)
Water
Tonic water (for glowing effect)
Whipped cream (optional)
Plastic cups

Directions

Prepare the Jello: Start by making the Jello according to the package instructions, but substitute half of the water with tonic water. This is what gives your Jello the glowing effect when under black light.
Pour into cups: Carefully pour the Jello mixture into plastic cups. Make sure not to fill them to the brim as the Jello will expand a little while setting.
Refrigerate: Place the cups in the refrigerator and allow them to set. This usually takes about 2-4 hours, depending on the Jello brand.
Add whipped cream (optional): Once the Jello is fully set, you can either leave it plain or add a generous dollop of whipped cream on top for extra flavor and texture.
Glow under black light: To see the magical glowing effect, place the cups under a black light. The tonic water will react to the light, making your Jello cups shine beautifully.
Serve: Now you are ready to serve your Glow in the Dark Jello Cups at your party! Enjoy the amazed looks on your guests’ faces.
