Spending an evening under the stars is one of the best parts about summer! This 4th of July, try these glow-in-the-dark recipes and activities that are sure to brighten the night sky.

Note: While the following can glow in the dark on their own, for increased fun, use a UV light to boost glowing power. UV lamps, lightbulbs, or flashlights are available at big box retailers, hardware stores, and online.

RADIOACTIVE REFRESHMENT
You don’t have to live in an apocalyptic wasteland to enjoy this easy and delicious drink. The secret to the glow is tonic water. According to Scientific American, tonic water contains a chemical called “quinine,” which is made from tree bark and has a bitter taste. Quinine absorbs ultraviolet light and releases blue light. So, under a UV light, the quinine in the tonic water gives off a fluorescent effect. Science!

Also, 12 oz. of regular tonic water has around 32 grams of sugar so we opted for diet tonic water.

Ingredients

  • Clear or light-colored juice or soda (we used white juice and lemonade) 
  • Diet tonic water

Instructions
Mix one part drink to ¼ part diet tonic water. Chill and serve.

Note: You can experiment with the ratios of juice to tonic water, but remember, the tonic water is bitter. 

The white grape juice (left) completely diminished the bitter taste, but it didn’t glow as vibrantly as the lemonade (right). The lemonade was slightly bitter, but still refreshing.

GLOW-IN-THE-DARK GELATIN
Now that we’re all experts in quinine, we can apply our knowledge to edible treats. In this case, flavored gelatin!

Lighter-colored flavors work best, like lemon and lime. The red, blue, and orange flavors will still glow, but not as intensely as the green or yellow gelatin.

Ingredients

  • 1 3 oz.-box flavored gelatin
  • 1 ½ cup boiling water
  • ½ cup diet tonic water
  • Cooking spray

Pour flavored gelatin into large bowl. Add boiling water and stir until gelatin dissolves, about two minutes. Add tonic water and mix. The mixture will be bubbly, that’s normal. Spray a 9-by-13-inch casserole dish or any size container you have or want to use. You can also pour into fun-shaped molds. Refrigerate at least 4 hours or until firm. 

If you have cookie cutters, cut out shapes. Or scoop and serve in a clear cup and enjoy! 

DIY GLOW-IN-THE-DARK SLIPPERS
If you’ve ever had a difficult time finding your slippers in the dark, this craft is for you. Pick up some nontoxic, glow-in-the-dark paint from a craft store, big box retailer, or online. You can add the paint to your existing slippers or buy inexpensive slippers for the entire family!

Supplies

  • Non-toxic glow-in-the-dark paint
  • Slippers

Instructions
Decorate slippers with glow-in-the-dark paint. Don’t forget to paint the straps! 

COSMIC EGG HUNT
Egg hunts aren’t just for Easter. With this easy, quick craft, your little ones will have the time of their lives searching for eggs in the dark.

Supplies

  • Glow sticks
  • Plastic eggs

Instructions
Snap a glow stick to activate and fold or tie so it fits in a plastic egg. Larger eggs are easier to stuff while you may need to tape the smaller eggs shut.

Hide the eggs and let the fun ensue! 

Safety warning: If it’s really dark outside, hide the eggs in places that are far away from tripping hazards, bodies of water, sharp objects, and stairs or steps. We held our egg hunt at dusk, so it wasn’t too dark yet.  

Happy 4th of July!
