This Fourth of July, the group that puts on Nashville’s riverfront fireworks will introduce the city to bigger explosions than it’s seen before.

Tennessee-based Pyro Shows has run Nashville’s Fourth of July fireworks for 25 years. Each year the city asks for something a little different. This time, the company’s bringing out “big shells,” 24 basketball-sized fireworks. Each will shoot to about the height of the Eiffel Tower. Jim Huddleston, a technician for Pyro Shows, says viewers will be able to feel the difference.

“That ten-inch shell, once it leaves that mortar at about 200 miles an hour it’s gonna go up a thousand feet and break and if you were to put a point in the middle it would be about a thousand feet diameter all around that center point, so it’s pretty impressive,” he said.

To be safe, Pyro Shows has had to increase its so-called “fallout zone.” From inside a metal storage bin dubbed the “bunker,” the show’s five technicians will detonate an amount of powder that weighs as much as an African elephant, all in half an hour.

While many shows have been cut or trimmed back, the Nashville Convention and Visitors Bureau says the city’s display will cost well over $100,000. The show, funded by the CVB, tourism tax dollars, and private sponsors, will have 39,000 individual fireworks.
