Cocktail shakers

  1. Oct 26, 2009 #1
    I used a cocktail shaker once in one of my friends' shop.

    It seems that ice blocks melt faster when shaken in a cocktail shaker (the shiny, metallic one) than in a regular plastic bottle.

    Why is this? is it just because the different material of the two bottles?
    Does a cocktail shaker has a special part (the cap, maybe) that allows a faster melting of ice?

    Well metal is a better conductor of heat than plastic so what ever the temperature of the room the ice will melt faster in the metal shaker.
