Cans of Density

I have been interested to see if this experiment would work for a while but no one in my house drinks coke, actually we hardly ever drink fizz but on Friday I had a group of friends over to watch the Royal Wedding (it was sooooo lovely!) and we stocked up! I needed a can of diet coke and a can of normal coke, I bought both so it was the perfect opportunity!! Except I was so busy hanging bunting and licking the bowl after my Dad iced the cupcakes cleaning that I forgot about the experiment and my friends drank all the normal coke! So I made a few alterations to the experiment...
The theory is that a can of fizzy drink that has more sugar in it will sink because it is more dense than the water and one without sugar will float. This did actually happen! The diet coke apparently has no sugar so it floated and the can of Aranciata had 30.9g of sugar so it sank!

So the experiment worked which is actually just really lucky because this wasn't exactly a fair test. There is a whole list of different ingredients and the cans themselves could weigh differently but  the difference in flotation ability is remarkable different so I'm counting it was a total success?
