It looks like an ordinary egg at first…
But drop it into this simple mixture, and something incredible happens.
The shell begins to bubble and slowly disappear.
The egg turns soft and ghostly.
And then—under a blacklight—it starts to glow.
This glow in the dark ghost eggs experiment is one of those activities kids can’t stop checking on. It builds anticipation, sparks curiosity, and turns a simple science concept into something that feels almost magical.

🔬 WHAT’S HAPPENING?
Why does the eggshell disappear?
The vinegar reacts with the calcium carbonate in the eggshell, causing it to break down and dissolve. What’s left behind is the soft membrane of the egg.
Why do the eggs glow?
Tonic water contains quinine, which glows under UV light. When the eggs soak in the mixture, they take on that glowing effect.
💡 EXTEND THE FUN
- Try drawing faces on the eggs before soaking them
- Test different liquids to see what happens
