Without fail, fireworks-related injuries spike around the Fourth of July in the United States. Between June 22 and July 22, 2012, more than 5,000 people ended up in the emergency room after being hurt by fireworks, most with burns to the hands, head or face, according to the U.S. Consumer Product Safety Commission (CPSC). Bottle rockets and sparklers, the favorites of children, were linked to at least one-fifth of those injuries. Besides harming people, fireworks can unsurprisingly cause fires - and extensive property damage. In 2011, fireworks were behind an estimated 17,800 blazes resulting in about $32 million in damage, according to the National Fire Protection Association.
