The 1795 time capsule that was placed under the Massachusetts Statehouse by Paul Revere, Samuel Adams, and others will be opened soon. Officials from the state as well as Boston's Museum of Fine Arts will reveal what the time capsule holds at 6pm on Jan. 6, 2015, USA Today reports. The capsule was last opened in 1855, its contents documented and cleaned, and this year on Dec. 11 the 10-pound box was taken out from under the statehouse cornerstone. It is believed to contain items including coins, newspapers and other documents, and an engraved silver plate. (More time capsule stories.)
