🌊 Glow-in-the-Dark Ocean Jar Recipe
🧂 Materials:
-
1 clean clear jar (mason jar or plastic bottle with a lid)
-
Water
-
A few drops of blue food coloring or blue liquid watercolor
-
Glow-in-the-dark paint (non-toxic, water-based)
-
Optional: Glitter, small sea creature toys, tiny shells, sequins
-
Glow sticks (optional, for temporary glow)
-
A few drops of clear glue or baby oil (for slow motion effect)
-
A UV light/blacklight (to charge the glow paint or for best glowing effect)
🧪 Instructions:
-
Paint glow-in-the-dark paint inside the jar:
-
Use a brush or cotton swab to dab or streak glow-in-the-dark paint along the inside walls of the jar. Let it dry completely.
-
Tip: Use different colors for a more magical effect.
-
-
Add water to the jar (fill about ¾ full).
-
Add a few drops of blue food coloring to tint the water like the ocean.
-
Optional: Add clear glue or baby oil to create a swirling, slow-moving effect.
-
Drop in glitter, tiny sea animals, plastic fish, or sequins for extra ocean vibes.
-
(Optional) Crack a glow stick and add it to the water for instant glow. Make sure it’s sealed, or cut it open and pour (with caution, gloves, and adult supervision).
-
Seal the lid tightly — hot glue around the rim if kids will shake it.
-
Charge the glow-in-the-dark paint by placing it in sunlight or under a UV light for a few minutes.
🌟 How It Works:
The glow-in-the-dark paint absorbs light and glows when it’s dark. For maximum brightness, use a UV light to “charge” it. The water and add-ins give it the look of a tiny glowing ocean.
