There is an e-mail going around about Water versus Coca-Cola, putting forth some very interesting claims about it's ability to do things. Mythbusters tested those and here's the final results:

Cola is able to remove bloodstains.

confirmed

The cola was able to emulsify bloodstains.



Cola is able to clean rust.

busted

The cola was unable to break down rust deposits.



Cola is able to clean chrome.

confirmed

It surprisingly cleaned the chrome better than the commercial chrome polish used for comparison.



Cola is able to dissolve a tooth overnight.

busted

The tooth did start to dissolve, indicating that with enough time it could be completely dissolved. However, the acidic solution used for comparison was much more effective in dissolving the tooth.



Cola is able to dissolve steak.

busted

The cola just gave the steak a soft, pasty consistency.



Cola is able to clean a penny.

confirmed

Results were good. The only part of the coin that was not cleaned was an area where a bubble had formed.




Cola is able to clean battery terminals.

plausible

It works, but it was hard to tell if plain water did not perform just as well. The cola did not do anything spectacular.



Cola is able to remove greasy stains in your laundry.

busted

No effect at all.



Cola is able to degrease engines.

busted

The cola did not remove any of the grease.



Cola is able to kill sperm.

busted

The MythBusters added cola to some slides and saline solution to others. They counted the number of live sperm they could see through a microscope camera in one minute, and found that the number of live sperm in both saline and cola was relatively the same. With the help of Dr. Turek they determined that cola doesnt do much more than dilute the sperm.
