Kids don't need a gymnasium to get exercise on a cold winter's day. This version of volleyball can be played indoors without risk to lamp or limb.
1. To play, first tie a piece of yarn or string across a 10-foot playing area, about 1 foot above the floor. Divide the players into 2 teams and have them set up crab style (faceup, leaning on their hands and feet) in their stocking feet on each side of the string.
