Fireworks have become staples of Fourth of July celebrations but their history goes back much farther. Fireworks were invented in China and although their exact date of invention is unclear, the earliest documentation of fireworks date back to the 7th century. Tonight, Milwaukee will continue its tradition of July 3rd fireworks with the US Bank Fireworks Extravaganza. This year's show will feature five tons of fireworks, with 5,000 igniters lighting more than 20,000 shells. The show starts at dusk (around 9:30) and will last for about an hour.
