Filmmaker Casey Neistat shows a neat trick that can turn a shot full of water into a shot filled with whiskey all through... magic? Sleight of hand? Devil's work? Destiny? No. DENSITY.

It's obvious to mostly everyone who took some sort of physics class BUT alcohol is lighter than water, therefore it floats to the top or water sinks to the bottom or both but not neither. ANYWAY. The question is however, why does drinking alcohol make people heavy when drinking water doesn't. Riddle me that smarter people than me of the world. [Casey Neistat]
