What’s crazy is why bar owners have been pressured by hipsters to use a spherical ice cube in the first place, given that under the dimensional constraints of a cocktail glass a sphere with a certain diameter displaces only approximately half of the volume of a corresponding cube which fits in the same glass. What a waste.
^Not sure what kind of diluted watery drinks you order brahs, but while ice floats in water it does sink in alcohol. If it’s a hot day and I’m thinking of changing my serving of neat whiskey to one on the rock(s), the ice will stay down at the bottom of my glass. But I guess when you order your raspberry tonic & proseco, ice cubes tend to float on top?
The molecular structure of liquid alcohol is very different than that of liquid water and more complex. In particular, the spacing between molecules in liquid alcohol is larger per unit volume than that of ice. In other words, the density of alcohol is less than the density of water (either ice or liquid). For this reason, the ice cube will sink at the bottom of a glass of alcohol.

I think the reasoning (and Mobius can do the math) for a big ball of ice instead of cubes is that the ball doesn’t melt as fast. So, you’re able to sip your ice-cold vodka on the rock(s) without it getting watered down if you don’t finish it in 10 minutes (which you should, pussies).
