Glow in the dark eggs – a science experiment for kids. Easily create a naked egg through a chemical reaction of dissolving an egg’s shell in vinegar. Make it glow with this added ingredient for extra creativity and fun! 

Glow in the Dark Eggs

Did you love our 5 Minute Science Experiments for Kids? We wanted to come up with some more ideas for you to enjoy!

At our house, we’re big science lovers. We love making fun science experiments with the kids that aren’t just the basic experiments, but that have a fun twist in some way. We found out that by using a highlighter marker as a dye, you can make the classic rubber egg science experiment glow in the dark!

How does it work? The dye in the highlighter marker is highly reflective, so when you shine a black light or a flashlight on the egg, it glows in the dark! You can also use this experiment to teach kids about osmosis, chemical reactions, and why vinegar dissolves egg shells.

If you don’t have a highlighter marker, you can also use the inside of a glow stick to make the eggs glow.

Glow in the Dark Eggs Supplies:

Not many ingredients are needed in this science experiment. Many of these supplies are probably found in your own home!

• Eggs
• Jar
• Highlighter marker
• Scissors
• Vinegar
• Flashlight or black light

Glow in the Dark Eggs Directions:

This process will take a few days but only take a few minutes to prep.

First, fill a jar with vinegar and set aside.

Cut open the highlighter marker and drop the ink pad into the vinegar. Make sure you squeeze the pad to remove all of the ink from the highlighter pad.

Carefully place one or two eggs into the jar. Set the jar on the counter for about 3 days.

Remove the eggs from the jar when bits of shell rise to the top of the jar. Rinse any remaining shell from the eggs.

Next, dry off the eggs and take them into a dark room.

This is the fun part! Shine a black light or flashlight on the eggs to watch them glow. The highlighter ink reacts with the light, making the egg glow!

Once you’re done admiring the egg’s glow, you can pop the egg open to examine the parts of the egg. The squishy membrane, the egg white, and the egg yolk are all clearly visible when these eggs are popped, which makes it a fun lesson in themes including the construction of an egg, osmosis, and chemical reactions.

What Happened?

A shell of an egg  is made up of calcium carbonate. If you soak this egg shell in vinegar, you start a chemical reaction that dissolves the calcium carbonate shell releasing carbon dioxide gas. The egg insides remain intact and are held together by a membrane just inside the shell.
