Check the tare weight or (TW) on the tank this is the weight of the cylinder empty. TW 18.5 would be the weight of the bottle empty. If you weigh your bottle and it weighs say 27 pounds 27-18.5=8.5 pounds left in the cylinder. You can tell if a propane tank is empty by shaking it an listening to it.
On September 13, 2014, Fort McHenry in Baltimore held a 200th anniversary celebration to mark the writing of the âStar Spangled Banner.â (Getty) âThe Star Spangled Bannerâ has been the official U.S. National Anthem since 1931 and is commonly heard today before sporting events and other patriotic gatherings. The lyrics â at least those to the first verse â have become ingrained in Americaâs culture, as much as apple pie and baseball.
Here's a refresher course on the history of the âStar-Spangled Banner.â. The banner. The poet Francis Scott Key described a giant flag that flew over Fort McHenry in Baltimore. National Park Ranger Jim Bailey points to a replica of that flag that's 30 feet tall and 42 feet wide. Each of the 15 stripes is 2 feet in width, or as Francis Scott Key would write, 'very broad,' and each of the stars measure two feet from point to point, or as Key would write, 'very bright'. So the broad stripes and bright stars of the 'Star-Spangled Banner' are not a poetic exaggeration of Key.
