The latest creation at Listerine is the new on-the-go Ready! Tabs. The tablets transform from a solid to a liquid in 40 seconds, neutralizing bad breath odors and leaving you with fresh breath for up to four hours, according to the company.   These solid tablets don’t contain any “mouthwash” (or liquid of any kind, for that matter).
