Glow in the Dark Jello

Glow in the dark Jello shots (or larger party centerpieces made in a Bundt pan) are an essential party trick that’s part science project, part Halloween decor, part nifty excuse to knock back some gin and tonic in unique form under black lights. Here’s how to make them.

Several plates with fluorescent glowing Jello molds

Rest assured, the spirits summoned for these ghostly glow in the dark Jello shots hail from a bottle, not the supernatural. It’s an essential party trick that’s part science project, part Halloween decor, part nifty excuse to knock back some Jello shots. And mostly gin and tonic. Black lights required.–Renee Schettler

Special Equipment: Fluorescent UV light; gelatin molds or Bundt pans of any size or shot glasses or anything you can think to use as a mold or just use a baking dish and some spooky-shaped cookie cutters

Ingredients


Directions

Cut the gelatin sheets into small pieces using scissors and place them in a large heatproof bowl. Pour 1 cup gin over the gelatin and let it rest until the gelatin starts to soften, about 10 minutes.

Place the bowl of boozy gelatin in the microwave and heat on high power for 1 1/2 minutes or place the bowl over but not touching a saucepan of simmering water. Stir until the gelatin has completely dissolved. Do not let the gelatin come to a boil. Remove from the heat.

Stir the remaining gin into the gelatin along with the lime or lemon juice. Then add the chilled tonic water, pouring it in as slowly and carefully as you can to keep it from fizzing. You want to lock in all those bubbles so they have a stunning effect in the Jello.

Slick your gelatin molds or shot glasses or whatever containers you intend to use with a paper towel soaked with vegetable oil. Pour the gin and tonic mixture—hold the mixture low to the molds and be sure to pour slowly and carefully to minimize bubbling—into your gelatin molds or glasses or even into a baking dish (you’ll later need to cut the Jello into cubes or shapes using a knife or spooky-shaped cookie cutters). Place in the fridge to set for about 6 hours.

Now’s the fun part. Serve it under a fluorescent UV light. The darker the atmosphere, the better the effect, so it’s best at night, with the lights turned out and the UV bulb as close to the Jellos as possible! Originally published October 28, 2011.

    What Else You Need To Know About Glow In The Dark Jello Shots

    • Glow in the dark Jello shots
    • This glow in the dark Jello works just as well in shot form as opposed to a single large mold, a fact that we can personally vouch for. You could also opt for teensy brioche molds, teacups, or, well, heck, just about anything will suffice.

    • Glow in the dark Jello for teetotallers
    • Want to serve this specter of a spectacle to kids or teetotallers? The rather crazily creative author of the recipe swears it works just as well when made without the gin. Just substitute tonic water for the gin as noted in the recipe above.

    • What makes glow in the dark Jello glow
    • So why are they glowing that ghastly and ghostly pale blue color? The answer is that quinine—the bitter flavoring in tonic water—glows under a UV fluorescent light, which can easily be found at hardware stores or online. The author suggests, for sheer shock value, letting the gelatin sit on the table with the lights on without drawing undue attention. Then place your fluorescent bulb as close to the Jello as you can before you switch off the lights.

    Recipe Testers' Reviews

    My kids (ages 25 and 27) were totally jazzed about this glow in the dark Jello. Having their experience at making Jello shots behind me, I forged ahead. I split the recipe into 2 batches, since I don’t like gin, and they don’t like vodka. I followed the directions as written, and used lime juice for the vodka and lemon for the gin.

    I poured the Jello into waxed Dixie cups, like the dentist uses, and allowed them to set. That way there’s no oily taste from the molds, and you just peel them back to eat.

    After bringing them out on the deck, where everyone was standing by with black lights, I can say the kids and adults alike LOVED this one. The Jello shots not only glowed, they literally lit up the night. My husband has an industrial-size black light for his work, so we got to really see what these can do. Who needs outdoor lighting when you could almost read by the light these gave off? We all agreed the texture is good, but the alcohol with the tonic water makes for a little bitter aftertaste.

    We all found that 2 cups of alcohol is overwhelming. I don’t drink often, so I thought that might be just me, but they all agreed. I only used 1 cup of gin in that batch, and they found it much more palatable. I will certainly do this one again, but will decrease the alcohol content and maybe add something to sweeten it to offset the bitterness. All in all, totally fun.

    1. This weekend’s jello shots will never be the same! Thanks for the heads up on the difference between brands. Can’t wait to try it.

      1. Can’t wait to hear what you think, Lorraine! Also, a reader told us that the pictures of people’s glow-in-the-dark mouths after they’d gulped the shots were a riot. Just wanted to make certain you had a camera at the ready…

    2. We did this for a fundraiser at a bar in the Castro a few years ago and was lots of fun. Swapped out the gin for vodka. As people got drunk the pics of people’s glowing mouths grew in frequency.

      1. The most essential element, Vicki, is that you still use tonic water with quinine, which is what has the glow-in-the-dark effect under the right light. As for the tequila and diet tonic combo, we can’t speak to that, but clearly you can! Have fun making and imbibing this…

    3. This is just a great idea for Halloween and versatile for other times of the year. My pediatric eaters will think this is the best thing since…Halloween. Very, very cool.
      Thanks for something different but also the general advice about gelatin sheets. I have been trying to solve this problem about how to calculate proportions for other reasons. Definitely a winner and so much fun.

    4. If you have the means and skills, try making some ‘coasters’ with UV LEDs and rechargable batteries. It would make your UV source more subtle and portable…
