The 2014 Fourth of July fireworks show for Nashville will be the biggest and longest ever, producers say. Here it is, by the numbers:

• 30,000 shells, or eight tons of fireworks
• 27 minutes long, the longest by 2 minutes
• 100 miles of copper wire to be used to connect devices and shell launchers
• 10 inches in diameter, the size of the biggest shells, which makes them larger than basketballs
• 1,000 feet, the distance most shells travel into the air, which is about a quarter mile
• 300 yards, the width of the bigger shells when they explode
• 200 miles an hour, the speed at which fireworks are launched
• 1,000 feet, the length of the firing range by LP Field
• 12, the number of men who work six-to-12-hour days to build the show
• 24, the number of hours to tear down
