This is a clip from a show that highlighted some of Ben Franklin's science experiments. The cast and crew were amazing, but alas, the show never aired. The host is actor/comedian Kevin Pollak. Here we are demonstrating one of Franklin's favorite gadgets called a Leyden jar. In this clip, actor Marc Evan Jackson is actually getting shocked by the Leyden jar, and his reaction is quite real. While the charge in this clip was harmless, a large Leyden jar can hold enough of a charge to kill a person.
