File her nails in the office? Never! Comb her hair at the table? No way! But apparently associate beauty editor Kate has no problem brushing her teeth on a subway platform. After attending Colgate's launch party for these single-use toothbrushes (Wisps, $2.50 for four; drugstores), she stashed a set in her bag and headed back to the office. Waiting for the train, she couldn't resist unwrapping one of the tantalizing little brushes. The blue bead released a minty flavor as the plastic bristles scrubbed her teeth (no rinsing required). When the train pulled in, she realized that, yes, she was brushing her teeth in public. These brushes are irresistible: Don't say we didn't warn you.
