DULUTH-At 10:10 p.m. on the Fourth of July the Northland's darkened sky exploded in color with professional and amateur firework displays.

According to a 2009 consumer expenditure survey, the average American household spends about $420 on home pyrotechnics.

Some vendors said they will make tens of thousands of sales on the Fourth of July.

The 2009 Census also showed that the U.S. imports more than $200 million worth of fireworks from China each year.

But some locations have local partners with fundraising options supporting causes right in our backyard, parent of Lakeview Christian Academy students Jan Swanson said.

"It's been really crazy like the last four days. We've had lots of people coming in," Swanson said.

Teaming up with TNT Fireworks, the group volunteers to sell fireworks outside Duluth's Cub Foods to help about 14 high school seniors planning to go on a trip to give back.

"So they're hoping to go to Chicago and they do some inner city activities and work and visit some churches and do some things like that and they have to raise the money for their class trip," Swanson said.

"Each day has gotten progressively busier. I think we had about 200 in sales a week ago and yesterday there was like 3,000 in sales," Swanson said.

And although consumer expense statistics show older folks are more likely to spend money on these mini–shows, Swanson said kids seem to push along the purchases.

"The little boys want lots of noise and the little girls want lots of color," Swanson said.

Kids at Lakeview Christian Academy typically take at least one mission trip each year.
