VIDEO: Behind the Scenes with Newton Fireworks Master Tony Gentile

You "ohhhh" and "ahhhh" as they light up the sky in honor of the Fourth of July. But have you ever wondered what it takes to put on a spectacular fireworks display?

is put on by the legendary Tony Gentile and his crew of fellow Garden City residents. Each year, a spectacular display lights up the sky above Albemarle Field on July 4. 

But Gentile does not restrict his firework talents to Newton. In fact, he recently set up two fireworks displays in the town of Wilmington, MA.

In Wilmington, two firework displays mean plenty of man hours in advance to get ready for the show.

Gentile and his crew spent much of Saturday preparing plastic tubes and filling them with explosives along the  football field.

Then on Saturday night, the group put on the first of Wilmington's two fireworks shows, firing off several hundred shells. But that is nothing compared to Tuesday night's 30-minute display that includes about 3,000 shells and tubes of explosives lined up for close to 100 feet.

And all while Gentile and his crew work, they are doing so under a watchful set of eyes. Wilmington Fire Lt. Dan Hurley has for about 12 years monitored the fireworks displays while he's joined at some point during the day by the State Fire Marshal.

While the town aims to put on a great display for its residents, the top priority always remains safety.
