Zero-Gravity Sports League In Development
Jonathan writes "A company that provides weightless flights to paying space tourists is developing a league around a sport that is designed for a zero-G environment." From the article: "The sport is called 'Paraball'...originally short for Parabolic Football," Persaud told SPACE.com. "The game really isn't like football anymore as the rules have developed, but the name has stuck," he added. [..] "The International Parabolic Sports League (IPSL) I plan to start with seven U.S. based teams, plus one Toronto-based team. Initially all League games would be played from the Las Vegas, Nevada airport, but we'll have 'home' games when the Zero-Gravity Corporation are able to bring their aircraft to that many cities over the time span of the league's season."
In "The Inventions of Daedalus", scientist and author David E. Jones points out that Xenon is a noble gas with a density greater than water. If you combine Xenon with oxygen and put it in a really big tank, you will have a breathable gas in a tank, in which human being can float. By combining xenon with appropriate amounts of nitrogen, you can get the density close to that of humans, and it will be similar to weightlessness. Wikipedia points out that Xenon has some anaesthetic effects, which would come in handy for those bruising scrimmages...
