| Did you know: |
On July 4, 1776, the Continental Congress in Philadelphia approved the Declaration of Independence, the first step in turning the 13 colonies of England into the United States of America.
|
| Speaking of the Declaration, the original resides on display at the National Archives Building in Washington, D.C. However, a copy, one of only 200 printed off the original, was purchased by a man in Tennessee at a thrift store for $2.48 in 2007. It sold at auction for $477,650! |
| There's more than magic in our Fourth of July fireworks; there's some chemistry, too. Titanium and iron are used to generate sparks. The brilliant blue is produced by copper compounds. And barium is used to create green colors in fireworks. |
