(PhysOrg.com) -- Ken Harvey, former linebacker for the Washington Redskins is trying to capture the imagination of young people by proposing a 21st century game of "Float Ball" to be played in zero-gravity. The Xtreme game of Float Ball combines elements of football and basketball with weightless players bouncing off walls, banging up against each other with the objective of moving varied colored floating balls to each end of the playing field. Extra points are given for stuffing a player carrying a designated color ball into a hoop. Initially, the game can be played in retrofitted grounded planes. The next step may include "Float Ball on the Moon" and perhaps someday a "Float Ball" stadium on Mars. Sounds extreme and perhaps lofty, but there´s science behind Harvey´s plan.
