I have an idea how to spend some time during the party. The Thunderer is the winter game. During the party you can organize games in the street for your guests. Take some empty cans and build pyramid from them. Then from the defined distance throw snowballs at pyramid. One or another who will bring down more cans just for three throws is the winner.

This game will bring you unforgettable pleasure but take care of your guests because cold weather can have an influence on their health.

P.S. After all such game can develop into usual snowball fight, so you will get pleasure as well.
