Looking for a fun activity with the kids? This snack is a science project and a tasty treat in one. Glow in the dark Jello is safe to eat and so much fun to play with!
Since Halloween is still a few weeks away, you have plenty of time to prepare! In my case, I needed a treat for a party with a “light” theme. Either way (not that you need an excuse), this is a great little easy treat with an added bonus!
Please the minds of those little mad scientists this season with this fun experiment that they can eat. Tricks and treats are all the rage around Halloween, so this fun party trick is always welcomed and well received, especially with the kiddos!
Why You’ll Love This Recipe
- Minimal ingredients and steps. If you’ve ever made jello from a box before then, you already know how easy it is to blend together with boiling water. This recipe is very similar to the “normal” way you’d make jello, but with a simple and easy twist to keep it unique.
- It tastes great! If you already like lime jello, then you’re in for a real treat! This jello will have a subtle carbonated flavor added to it, so kids with sensitive palates may not enjoy it as much as others, but it’s still really yummy.
- You can try different jello flavors. While I’m told that lime jello lows and shows up the best, nothing is stopping you from trying any number of different flavors. Science experiments are all about finding new results, so why not? Use your favorite jellos and really have some fun!
Glow in the Dark Jello Ingredients
Boiling water: You will need 2 cups of boiling water so that you can dissolve the jello powder.
Tonic water: This is actually what makes the jello glow! You will need 2 cups of it to make this science experiment work.
Jello: Use (2) 3-ounce-sized packages of lime jello mix.
Toppings: For a tasty topping, you may wish to add whipped cream and sprinkles.
Also needed: To really get the full effect of this experiment, you will need some clear jars or cups as well as a working black light.
How to Make Glow in the Dark Jello
Boil the water in a pot and whisk in your jello powder until dissolved. This should take about 2 minutes.
Add in the tonic water and let it rest until the bubbles rest.
Pour the desired amount of jello into your containers and place them into the fridge to chill and set for 2-3 hours.
Top with whipped cream and sprinkles for garnish.
Serve your jello in the dark under a black light to reveal the glow in the dark features of this tasty lime dessert.

How does it glow?
Tonic water glows in the dark under the help of a nice black light. This is because of the fluorescence of the quinine in the tonic water. Unfortunately, this quinine makes the water a little bitter, which is why it’s in the mixed drinks section in stores, because it’s often served with sweeter drinks.
How long is lime jello good for?
You can keep this jello in the fridge for up to a week which should give you plenty of time to experiment with the kids. Prepping the jello the night before and seeing the results the next day will ensure that the jello has fully set before being served.
Is tonic water alcohol?
Tonic water is a nonalcoholic carbonated soft drink added to mixed drinks with alcohol, but it does not contain alcohol on its own. In fact, its often enjoyed for its simple health benefits in place of sodas too.
