• Nov 25, 2014 at 5:49 PM

Pyro Shows technicians Chris Hill and Sean Mahoney assemble one of the many structures securing 4- and 5-inch mortars that will fire a combination of 10,000 explosives. Lafollette, Tenn.-based Pyro Shows made their return to the Science Hill campus Wednesday to unload and set up the Pepsi-Beverages Co. of Johnson City and the City of Johnson City 29th Annual Independence Day Fireworks Celebration on the grounds of Freedom Hall Civic Center. Workers also set the mortars to fire in sync with an orchestrated sound track. Meanwhile, Pepsi employee, Donnie Dye, spray paints a colorful company logo on a large berm across from the main viewing area.
