How to Make Glow in the Dark Fireworks in a Jar
Step-by-Step Instructions:
-
Fill the Jar: Add warm water to your clear jar, filling it about ¾ full. This leaves room for the “fireworks” to float and swirl.
-
Mix the Paint: In a small bowl, combine 2–3 tablespoons of vegetable oil with a few drops of glow in the dark paint. Add food coloring here if you like. Stir gently with a fork or toothpick.
-
Create the Magic: Slowly pour the oil and paint mixture into the jar. The oil will float on top, and the glow paint will begin to drop into the water, looking like glowing fireworks!
-
Lights Out: Turn off the lights or dim the room. Want a serious wow factor? Shine a blacklight to amplify the glow.
-
Recharge & Repeat: When the glow starts to fade, place your jar under a bright light to recharge it.
