helium

At the 1976 Pro Bowl, Ray Guy, a punter for the Oakland Raiders, punted aball that hung mid-air long enough for officials to question whether thepigskin was filled with helium. The ball was found to be filled with air,but since then many have tossed around the idea that a helium-filledfootball would outdistance an air-filled one. Students at Ohio StateUniversity conducted an experiment to test this myth. They used twoidentical footballs, one air filled with air and one filled with helium.Each football was kicked 39 times and the two footballs were alternated witheach kick.

Variables

  • trial - Trial number.
  • air - Distance in years forair-filled football.
  • helium - Distance in years for helium-filledfootball.
