A time capsule set to be buried July 4 to commemorate the 250th anniversary of America’s founding was unveiled this week – and won’t be reopened until 2276. The cylindrical, three-layer pod was designed by some of the country’s leading scientists in the hope that the artifacts it will hold remain intact when unearthed from Independence National Historical Park in Philadelphia 250 years from now.   “This is truly America’s Time Capsule,” said Rosie Rios, the chair of America250, which is organizing the vessel and several other events marking the semiquincentennial.
