A viral video is spreading on YouTube. The video is entitled, “Still drinking coca cola watch this! It has over 10 million views and counting. Other remixes and contrary versions are also existing. The video has earned over 12 thousand likes and almost equal number of dislikes. It got my attention through Facebook shares.
The video goes like this: A boiled egg with intact shell was placed in a toddler training cup, filled with Coke and let stand for 365 days. The egg was still sound after a year, with slight discoloration and no shell. The shell was pulverized by liquid Coke.
The author emphasized, Coke contains caffeine citrate, citric acid and phosphoric acid. The egg shell is made of calcium, phosphorus and sodium which can be dissolved by Coca Cola ingredients. Drinking the beverage always might seriously damage teeth and cause osteoporosis.
Most comments are negative statements. Some agree while other are just trolling. Here are some of them.
1) There is no way someone gonna let the coke stay in mouth for a very long 365 days…
2) …And coke does not stay in stomach that long either.
3) Water intoxication probably kills, not the coke itself.
4) Soda also leaves a liver scar that may lead to hepatitis B.
5) Thanks to coke, the boiled egg has been preserved for a year.
6) Fresh squeezed lemon juice will do the same in just two to three days. Vinegar would do the same. Coke is much safer.
I setup my own experiment. I got broken egg shells. I never used the gelatinized egg cause only the shell was my concern. Coke only affected the shell as shown on video. I divided the broken shells to two. I soaked the first in Coke and soaked the second in vinegar.
The immediate and heavy bubble formation was due to releasing CO2. I waited one hour and inspected it again. Less bubbles were appearing and the shell remained submerged in liquid. A relatively slower reaction as compared to other.
to be continued…
After 15 days. The egg shells in vinegar turned to small pieces. Bubbling stops and no color change was observed on vinegar. The eggs shells in coke softened and broken to smaller pieces but not as small as in vinegar. The shell color turned dirty brown. The coke itself had a very pale color.
