Miami-Dade fire inspectors are on the road this July 4th, checking out more than 20 tents selling fireworks.
"If it flies into the air or explodes it's probably illegal," inspector Javier Camps said.
The state fire marshal has a 60-page list of approved sparklers, fountains, snakes and glow worms. Even popular Roman Candles are not allowed, unless you have a permit.
Some tents sell fireworks that are technically illegal, because of a loophole in the law. Customers are usually asked to sign a waiver that they'll be used legally – usually a sign that what they're buying is not approved for general use in Florida.
Inspectors are working on this holiday to make sure those products aren't sold in Miami-Dade.

Each year in the U.S. there are more than 80,000 injuries related to fireworks, mostly in children under the age of 15.
