Cambodian Coca-Cola meets Mr Science

This is a part of our Cambodia forums to chat about anything Cambodia-related. This discussion forum is at the top of our site because it's usually the busiest part of the expat community chatter with random topics on just about everything, including expat life, Khmer politics, Cambodian blogs we have or have come across, or whatever else our members want to discuss. Whether you're an expatriate, tourist, Cambodian or random traveler just passing through South East Asia, you are welcome to talk about anything or start new topics yourselves.

Nothing to contribute, but that's a great OP.

IT FLOATS, just like Diet Coke and unlike regular Coke.

My tentative conclusion: The stuff the Cambodian Coca-Cola factory is putting in regular Coke cans is not regular Coke. It is Diet Coke. (At least for this batch of cans.)

I wonder if that is a 'honest mistake' or if it perhaps cheaper to manufacture Diet Coke than regular Coke.

Would love to have some of the more science orientated types here critique my experiment and conclusion.
Another possibility is that the cans may not be filled with the stipulated 330ml either the machine had a fault or it could be deliberate to increase profit. Having less liquid in the can would reduce the SG somewhat. Thats something you could measure. If in fact you open it and it is 330ml then I suspect they have put less concentrate in the mix.

Edit Just found a SG value for Coke, its supposedly 1.042 in that case for a 330ml can to float the volume of liquid at an SG of 1.042 inside the can would be 330/1.042 approximately 317 ml. If there is 317 ml or less in the can Bingo! Of course this is a very rough and ready calk. You would also need to check the actual volume of "sinking coke" and weight of cans etc.

Sometimes I drink Coke and I'm happy, other times I'm sad.

I think I'm bi-cola.

Unbelievable that someone with an education and an (obvious) sharp and inquiring mind drinks many cans of coke a day. That shit is pure poison.

Why are you always so obsessed with the choices other people make? Do you want everyone to be like you?

Measured the contents of one can of Cambodian Coke (same batch) in a graduated cylinder. It was spot on exactly 330ml, maybe 331ml:

I am now looking for a BRIX hydrometer, if anybody knows where I might be able to find one.
