Ingredients You’ll Need

- 1/2 cup granulated sugar
- 1/4 cup unsalted butter
- 1/2 teaspoon salt
- 1 teaspoon tonic water (for glow effect)
- Neon food coloring (yellow, green, blue, or pink)

How to Make Glow-in-the-Dark Candy Popcorn Bombs
Step 1: Prepare the Popcorn
- Pop the popcorn and remove any unpopped kernels.
- Place in a large mixing bowl and set aside.
💡 Tip: Use plain, air-popped popcorn for the best results. Buttered popcorn may prevent the candy coating from sticking properly.
Step 2: Make the Candy Coatin
- In a saucepan over medium heat, combine corn syrup, sugar, butter, and salt. Stir continuously.
- Bring to a gentle boil and let cook for about 3 minutes, until the mixture reaches 230°F (soft-ball stage).
- Remove from heat and stir in vanilla extract, tonic water (for the glow), and baking soda.
- Quickly divide the mixture into separate bowls and add neon food coloring to each.
💡 Tip: Tonic water gives a blue glow, but for other colors, add neon food dyes for a more vibrant effect.
Step 3: Coat the Popcorn
- Pour the colored candy mixture over the popcorn and stir quickly to coat evenly.
- Shape into popcorn bombs by pressing small handfuls into balls while still warm.
- Place on parchment paper to cool completely.
💡 Tip: Lightly grease your hands with butter or oil to prevent sticking when forming the popcorn balls.
Step 4: Serve & Watch It Glow!
- Arrange the popcorn bombs on a tray.
- Turn on a black light and watch them glow!
- Serve and enjoy the magical, glowing treat!
Helpful Tips for the Best Glow-in-the-Dark Popcorn Bomb
✔️ Use a candy thermometer – This ensures the sugar mixture reaches the right temperature for a crunchy coating.
✔️ Work fast! – Once the candy coating is ready, you need to mix and shape the popcorn balls quickly before it hardens.
✔️ For extra glow, use vitamin B2 (riboflavin) – Mixing crushed vitamin B2 tablets into the sugar syrup enhances the glow under black light.
✔️ Customize the colors – Use different neon food dyes to match party themes!
