If you did a science fair project as a kid, chances are it was something like a potato-powered clock, or a baking soda volcano.  But a 14-year-old from Pittsburgh named Suvir Mirchandani might have actually done something useful.

In the heat of argument, people sometimes say some dumb things. For example, I once got in an disagreement with a coworker and told him that I was going to piss in his coffee. I didn't mean to say that. I meant to say "in his desk drawer" but it was all cleared up the next day when he reached into his desk drawer. He was so surprised he spit out the cup of piss I made him!
