(at around 23 mins) In the beach shootout scene when Frank's family is killed, Frank and his father are trying to kill a man who has taken cover behind the outdoor BBQ. Frank kills the man by shooting the propane tank with his shotgun causing it to explode. However this would not actually happen, shooting a propane tank with a gun, even a shotgun would not make it explode. Now the shotgun might have enough power (depending on what kind of loads Frank was using) to penetrate the propane tank, but it would not cause it to explode. In order for the propane to explode it would need an ignition source. Most people think that shooting a metal can with a gun will make a spark, but this is not true. Almost all bullets have a copper jacket and a lead tip, and neither lead nor copper make sparks when they hit metal. While Frank was using a shotgun, which has BB's instead of bullets, almost all shotgun pellets are made from either lead or copper, so they would not create a spark. See more
