Magic Glowing Eggs

Updated: Jul 28, 2020

Who knew you could change regular garden variety eggs into rubbery glowing orbs with transparent sides?! Read on to find out how!




🔲glass jars


🔲tonic water

🔲food coloring (neon will work best for glow)

We completed this project one way, but I wasn't super happy with the results. Therefore, I will add in my suggestions for changes and you can choose which way to go!

Begin by placing some eggs in a jar. The directions we followed said to mix equal parts vinegar and tonic water. However, my revised suggestion would be to mix equal parts vinegar and tonic water with a few drops of neon food coloring.

Seal the jars and observe what happens to the eggs. You will notice lots and lots of bubbles forming on the surface of the eggs. That is the vinegar starting its work. You will leave these eggs in their jars for 3-4 days.

Observe the eggs daily. You may not notice anything very different other than that the eggs seem to be growing. That part was really surprising to me! I actually worried that we wouldn't be able to get them out of the jars!

After 3-4 days, very carefully pour out the vinegar mixture and remove the eggs. BE CAREFUL! The eggs are still raw inside and will break if not handled carefully. You will notice the shell of the egg has dissolved (thanks to the vinegar!) Gently rub the rest of the outer shell away until you reach the protective membrane. (We broke two of our eggs during this process, so again I say be careful!) You will end up with a rubbery, translucent egg that will glow under a blacklight! (If you just use tonic water like we did, you might not get much of a glow. That's why I recomment the food coloring. It will dye the entire egg a nice neon color.)

After exploring the texture and color of your magic eggs, you can take them outside and watch them explode! Who doesn't want to see that?!


How did your magic eggs turn out? Did you use food coloring? Did it work? Share your photos/videos!
