Obama pedals bike at 3rd White House science fair [nbc4i.com]


WASHINGTON (AP) - It was an offer President Barack Obama couldn't refuse.
"You're welcome to try this out if you like," the Oakland Park, Fla., high school student said.
With that, a president who often laments a lifestyle that denies him the pleasure of driving eagerly hopped on the blue-and-silver bicycle in his dark blue suit and pedaled away, never mind that the machinery didn't take him anywhere.
"Only because these guys really want this," Obama said, gesturing to the small group of reporters and photographers who were brought to a White House garden to watch the president go from exhibit to exhibit at his third White House science fair.
He said afterward that it's "one of my favorite events during the course of the year."
As Obama pedaled, Payton Karr and Kiona Elliot, classmates at Northeast High School, explained their pedal-powered water filtration system. The collapsible, transportable emergency water-sanitation station filters E. coli and other harmful pathogens from contaminated water. During emergencies, the device can be assembled and broken down in less than an hour and can produce enough water for 20-30 people during a 15-hour period.
Karr and Elliot were among some 30 student teams that were invited to the White House to show off projects that won them top honors in science, technology, engineering and math competitions around the country.
