The eastern shore of Lake Erie is known as the "Sponge Candy Crescent." During the region's long winter months, this crunchy, chocolatey candy is a mainstay — especially for large gatherings and holidays. But come hot weather, you can't get the temperamental treat.

Ko-Ed Candies sells a lot of chocolate Easter bunnies, candy bars and other sweets, but co-owner Sandy Whitt says her customers mostly crave sponge candy.

Niagara Falls has long been a magnet for daredevils, but strict laws have kept them away for more than a century. That's expected to change Friday, when circus performer Nik Wallenda will walk a two-inch-thick wire above the giant waterfall. It's an exception officials hope will rescue tourism — and the city's economy.

You may have heard of "flash mobs," where a mass of people invade a public space to make a scene. Now the idea has been turned on its head by "cash mobs," where large crowds of consumers show up at small businesses to spend money. But it's not just about propping up the local economy.

It's 5 o'clock on a Friday, and mostly quiet in the Lander's Men's Store, a mom-and-pop clothing store in Jamestown, N.Y. But shop owner Ann Powers is anticipating a mob.

Only 7 percent of plastic waste in the United States is recycled each year, according to the Environmental Protection Agency. A startup company in Niagara Falls says it can increase that amount and reduce the country's dependence on foreign oil at the same time.

It all starts with a machine known as the Plastic-Eating Monster. Thousands of pounds of shredded milk jugs, water bottles and grocery bags tumble into a large tank, where they're melted together and vaporized. This waste comes from landfills and dumps from all over the United States.

Imagine driving without a speedometer and still trying to go the speed limit. Chris Montag, chief operating officer of Ladybug Teknologies, says that's analogous to going out drinking without a Breathalyzer.

"It's something we've done for hundreds of years, and nobody's ever had a tool and we guess ... that we're OK," Montag says. "But, really, how do you know when you've never been able to measure it?"
