The Fourth of July skies this year may not be as bright as in years past. That's because an explosion in China a few months ago destroyed 20 fireworks warehouses and the bulk of U.S. fireworks supplies.

That blast on Valentine's Day this year cracked windows up to 25 miles away and produced a rather unplanned and dangerous fireworks display for more than 24 hours over the port city of Sanshui.

A look at the aftermath shows buildings completely leveled. Not only did supplies explode but a ban on fireworks shipments was instated. The result? Chinese exports of fireworks are down 40 percent and with the Fourth of July just around the corner, the industry has been scrambling to make sure their shows do not fall short.

Here at home displayers dodged this rocket. According to Vincent Speciale, President of American Fireworks, he orders a year in advance so displays will not disappoint. He did say however that at least 50 percent of professional fireworks companies in the U.S. have contacted him in the last few months looking for needed supplies but Vincent is not a wholesaler. He says there is something else that has contributed to a grand finale for him.

"We don't depend on China alone, we use a lot of American made fireworks. We are one of the very few companies in the whole U.S. that still uses American made products," says Speciale.

There is a difference between the American and Chinese products. Chinese products are rounder and tend to give a flowering effect in the sky while the American made products are elongated and tend to go off in succession.

Speciale says that next year's supplies might also be low because during the Olympic Games this summer there will be no movement of explosives in China, so warehouses will likely be heavily back ordered.
