We put a can of coke and a can of diet coke in a beaker of water, and they both float - the regular coke's supposed to sink. Is there something we're missing?

Re: coke cans floating
I did this a few years ago and it worked properly. Air bubbles under the can? Maybe try another can of normal coke?

Re: coke cans floating
definitely works....
also check the temp of the water it may be a factor. I'm assuming both cans were room temp?

Re: coke cans floating
We have tried this too with no success. I just assumed that the pictures I had seen were American or something because they have a different recipe (everyone I know who has been there says "Don't drink the coke!"). A teacher tried with bottles first, and my thought then was the air bubble was making it float but then the cans did too.

Re: coke cans floating

we using 200ml size; would that make a difference?

Re: coke cans floating
hmmm... perhaps the water is too cold? What if you tried cold cans and room temp water? Our water comes out pretty cold, so might be worth adding some hot? I think we tried it last term so it would have been really cold then.
