When we heard that astronauts aboard the International Space Station took a spare toothbrush along on a spacewalk today and used it to help clean debris from around some bolts they needed to secure in order to install a power unit, it got us thinking.
Just how versatile are old toothbrushs? We know we've used them to:
-- Clean bike gears.
-- Get grime out of our hubcaps.
-- Get at the crust around a car battery's terminals.

Alex Zanardi, who was a star racecar driver when he lost his legs in a 2001 crash, has won a gold medal in the London Paralympics. The Italian, 45, beat Germany's Nobert Mosandl by more than 27 seconds to win the men's handcycle time trial. The race took place at Brands Hatch, a track that Zanardi has previously tackled behind the wheel of high-powered racecars.
"Last time I was here I was going about five times faster but I still love this circuit," he said this week.

"He's clearly the best asset the Democrats have," says GOP consultant David Carney. "Clinton is their best surrogate."
The image of the lone genius toiling in isolation, finally emerging with a brilliant new concept is compelling, even romantic. Too bad it's not true.
Instead, innovation thrives in ecosystems, much as microbes flourish in a warm, cozy petri dish.
"There's an important geography to where innovation happens," says AnnaLee Saxenian, dean of the School of Information at the University of California, Berkeley, who studies how regional differences affect innovation.
