Give your guests something to do besides tipple and watch a ball drop at your New Year’s Eve bash. This year, create a group time capsule. “Ask each guest to either bring or write down something that represents 2011,” suggests lifestyle guru Steve Kemble. “Then ask everyone to write down a prediction for the coming year.” Their contributions may run the gamut from sentimental to side-splitting. Place all the timely treasures in whatever sort of time capsule you care to fashion, and promise everyone you’ll open it at next year’s party. The responses will be a huge hit at your soiree the following year — plus it’s a great way to keep ‘em coming back, naturally.
