The Liberty Bell is a historical symbol of American Independence from the mid 1700’s. It’s located in Philadelphia, and you can Google that for more information. To “lick” the liberty bell is a TV sitcom invention; i.e. in “How I Met Your Mother” Barney comes up with the idea. But, it’s not a real thing. It was just a silly sitcom plot. In reality, the Liberty Bell is behind a guarded area, metal detectors, and a physical barrier. You can see it, but you’re not supposed to touch it. There is no “kissing” the Liberty Bell.
