Diet coke is less dense than regular coke.
Because the coke is 'diet', meaning it has less calories than the regular one.
The Diet Coke can floats because the sugar they put in regular Coke has been substituted by a lighter (less dense) substance (a healthier type of sweetness). The sugar is much denser that the artificial sweetener, so the Coke sinks and the Diet Coke floats.
