There were 13 original colonies
The American flag has 13 stripes that represents 13 of the original colonies. Unfortunately for us, there were actually only 12 starting colonies, since Delaware was never a separate colony. Delaware remained a part of Pennsylvania until the Revolutionary War. Before that, the “phantom colony” was switched between Pennsylvania and Maryland.
Ben Franklin flew a kite and discovered electricity
The story goes that Benjamin Franklin discovered electricity by flying a kite with a metal key attached to it during a lightning storm. When the kite was struck by lightning, the charged passed down the string and into the key. There is no real evidence to suggest that this story ever actually took place. In fact, many today argue that had it really happened, Franklin would have likely died from the electrical shock. It makes for a fun story, though.
Pretty much everything about Thanksgiving
While we romanticize the first Thanksgiving as being a peaceful and joyous meal between Pilgrims and Native Americans, the true story is something far less celebratory.

The image of Pilgrims and Native Americans breaking bread together was a fabricated PR tale of the time that is incredibly still taught in schools.
