A team of 10 skilled pyrotechnicians from firework display company Pyrotecnico put on the dazzling display in the Delaware River. Pyrotecnico puts on three firework shows during Wawa Welcome America — two on the Philadelphia waterfront and a special display at the Philadelphia Museum of Art for the Fourth of July. They also produce fireworks shows for the Phillies and Eagles as well as other displays around the country all year long.
Nearly 11,000lbs of explosives were loaded on to a barge at the Philadelphia Navy Yard and stuffed into computer-controlled launching equipment for Monday night's fireworks display at Penn's Landing.
The crew, with the help of a tug boat, positioned the barge in the middle of the Delaware River just south of Chestnut Street.
Right on cue to the music, each effect is executed and launches towards the sky.
