After making fun of his sister for selling scented candles as a school fundraiser, 13-year-old Hart Main of Ohio was inspired to invent "Mancans," candles that emit manly odors. Since thanksgiving he's sold 500 of the $5 handmade candles, so don't be surprised if your next candlelit makeout session takes place while the scent of "Grandpa's Pipe," "Sawdust," or "New Mitt" wafts through your boyfriend's apartment.
