It would appear from the research undertaken so far that our American cousins like to play games at what they refer to as "baby showers". Here is a game that Lady Bracknell will not be playing, either on her own blog, or, for that matter, anywhere else:
Melt the Ice
The day before the shower, freeze diaper pins, miniature pacifiers, tiny plastic babies, or similar items in ice cube trays. Give each guest an ice cube in a glass of water or other drink. The first person whose ice has melted so that the frozen item floats freely in the glass shouts, "My water broke!" and wins the game.
