DIET COKE FLOATS

If you place both a can of regular Coke and a can of Diet Coke in water, the Coke will tend to sink while the Diet Coke will tend to float. Do you know why?

Floating occurs because floating objects displace, or push aside, a certain amount of liquid. If an object displaces more than its weight in liquid, it floats; otherwise it sinks.

It seems it's the sugar in real Coke that makes it dense enough to sink. It also seems that it's the artificial sweetener in that diet version that's less dense, allowing those cans to float.

Then again, the Russians could be behind this.
