Glow in the dark Jello is an essential for parties of all sorts. It’s part science project, part Halloween decor, part nifty excuse to do shots. Here’s how to make it.
The great thing about this glow in the dark jello, other than its glowiness, is that you can serve it either before the meal as a solid gin and tonic–complete with its bubbles captured in the gelatin so it even retains a little fizz–or you can have them after your meal as a wonderfully crazy dessert. Either way, it’s best to set them on the table with the lights on without drawing undue attention to them. Then place your fluorescent bulb as close to the jello as you can before you you switch off the lights. This recipe has been updated. Originally published October 28, 2011.–Stefan Gates
What Makes The Jello Glow In The Dark?
This glow in the dark jello isn’t a cheat, and it’s not an optical illusion—it’s simply gin and tonic jello made by adding gelatin to a gin and tonic and letting it set. So why are they glowing that fantastic ghostly 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 on the web. The bigger the bulb, the better the glow. Think of it as part science project, part Halloween decor, part nifty excuse to do shots. Here’s how to make it.
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
Glow in the Dark Jello Recipe
- Quick Glance
- 25 M
- 11 H, 35 M
- Servings vary
- 2 packages sheet gelatin (enough to set 2 quarts firmly—usually about 50 percent more than listed on the package)
- 2 cups decent gin (if you don’t want to serve alcohol, you can substitute chilled tonic water)
- Juice of 3 large limes or lemons
- 1 1/2 quarts (6 cups) tonic water, chilled
- Mild vegetable oil
- 1. 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.
- 2. 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 and stir until the gelatin has completely dissolved. Do not let the gelatin come to a boil.
- 3. 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.
- 4. 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—again, pour it slowly and carefully to minimizing bubbling—into your gelatin molds or glasses or even into a simple 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.
- 5. Now’s the fun part. Serve it under a fluorescent UV light. The darker it is, 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!
Glow In The Dark Jello For Teetotallers
- 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.
