The ‘Egg in Cola for 24 Hours’ Video is Just a Prank

by Brett M. Christensen

A video that is currently circulating via social media websites purportedly shows what happens when an egg is soaked in cola for 24 hours.

The video shows an egg being placed in a glass and then covered with a mixture of Coke and Pepsi. Supposedly, after being left in the cola mix for 24 hours, the egg has become completely transparent and very squishy.

The implication is that the chemicals in the cola have fundamentally transformed the properties of the egg.

Here’s the video:

However, the video is just a prank.

In the final sequence of the video, the egg has simply been replaced by a splat ball squishy toy like those available at this Amazon listing:

Here’s a video showing such squishy eggs in action:

So, the video is just a harmless prank.

Reportedly,  the shell of an egg immersed in vinegar WILL dissolve over time resulting in a somewhat transparent shellless egg. Some reports also claim that cola will begin to break down eggshell if left long enough.

So, in the interests of science, I decided to conduct an experiment using cola in one glass and vinegar in another.

It appears that the vinegar is already starting to dissolve the eggshell after just a few hours. So far there is no change in the coke egg.

But, of course, even if the shell does fully dissolve, the result will be nothing like the squishy, stretchy, fully transparent “egg” depicted in the circulating video.


After about three days, the egg in the cola remains unchanged except for some discolouration of the shell. The egg in the vinegar is now soft although the shell remains intact so far.

Importance Notice

After considerable thought and with an ache in my heart, I have decided that the time has come to close down the Hoax-Slayer website.

These days, the site does not generate enough revenue to cover expenses, and I do not have the financial resources to sustain it going forward.

Moreover, I now work long hours in a full-time and physically taxing job, so maintaining and managing the website and publishing new material has become difficult for me.

And finally, after 18 years of writing about scams and hoaxes, I feel that it is time for me to take my fingers off the keyboard and focus on other projects and pastimes.

When I first started Hoax-Slayer, I never dreamed that I would still be working on the project all these years later or that it would become such an important part of my life. It's been a fantastic and engaging experience and one that I will always treasure.

I hope that my work over the years has helped to make the Internet a little safer and thwarted the activities of at least a few scammers and malicious pranksters.

A Big Thank You

I would also like to thank all of those wonderful people who have supported the project by sharing information from the site, contributing examples of scams and hoaxes, offering suggestions, donating funds, or helping behind the scenes.

I would especially like to thank David White for his tireless contribution to the Hoax-Slayer Facebook Page over many years. David's support has been invaluable, and I can not thank him enough.

Closing Date

Hoax-Slayer will still be around for a few weeks while I wind things down. The site will go offline on May 31, 2021. While I will not be publishing any new posts, you can still access existing material on the site until the date of closure.

Thank you, one and all!
