With Super Bowl Sunday fast approaching, we took a break from planning our parties (guacamole!) to research and report a couple of new fact-checks. We first looked at a claim arising from the controversy of underinflated footballs. New England Patriots coach Bill Belichick made the claim that atmospheric conditions could push a football’s pressure "down approximately one-and-a-half pounds per square inch." (Belichick's Patriots will face off against the Seattle Seahawks, coached by Pete Carroll.) We felt like basic science should be able to tell us whether that's even possible.
