Having discovered the joys of the "appletini" (vodka mixed with apple juice, cider or apple liquor) I have a question.

The garnish is a slice of apple and a Maraschino or glacé cherry on a cocktail stick. If the cherry is at the bottom of the stick it floats in the appletini, but with the apple slice at the bottom it sinks. Why? Surely the buoyancy of the two items combined is an absolute and their orientation should make no difference.

I shall leave it to the imagination as to the amount of 'tinis consumed before this anomaly became a burning conversation topic!
