Ingredients
Scale
Materials
- 1 clear glass or plastic jar with lid
For the Glow Effect
- Warm water – enough to fill the jar about ¾ full
- 2–3 tablespoons vegetable oil
- Glow-in-the-dark paint (washable, non-toxic) – small drops
- Food coloring (optional) – a few drops
Tools
- Fork or toothpick (for stirring)
- Small bowl (for mixing oil and paint)
- Optional: Blacklight (for enhanced glow effect)
Instructions
- Fill the jar: Pour warm water into your clean jar until it is about three-quarters full, providing the base for the glow-in-the-dark mixture.
- Mix oil and glow paint: In a small bowl, combine 2 to 3 tablespoons of vegetable oil with several small drops of glow-in-the-dark paint. If desired, add a few drops of food coloring to intensify the color. Stir well with a fork or toothpick until the paint is evenly dispersed in the oil.
- Add the mixture to the jar: Gently pour the oil and paint mixture into the jar containing the warm water. Pour slowly to allow the oil to float on top without mixing immediately.
- Observe the effect: Watch as droplets of the glowing paint suspended in oil swirl, burst, and float in the water, mimicking a fireworks display inside your jar.
- Turn off the lights: Create a captivating atmosphere by turning off ambient light to see the glowing paint come to life in the dark.
- Enhance glow (optional): For an even more vibrant glow, charge the jar under a lamp or shine a blacklight on it before darkening the room.
Notes
- Use washable, non-toxic glow-in-the-dark paint to ensure safety, especially for children.
- Do not seal the jar tightly if storing, to prevent pressure buildup or leakage.
- The glow effect fades over time; recharge the jar by exposing it to light before use.
- This activity is great for sensory play, nightlights, or educational demonstrations about density and light.
- Be careful to keep the jar upright to avoid mixing the oil and water prematurely.
