Mouthwash with light-up timer cap
Firefly mouth swoosh is a mouth wash for kids that utilizes a light-up bottlecap to tell kids when to stop "swooshing".You fill the cap with mouth wash, which automatically activates the cap. Then pour the contents of the cap into your mouth and start swooshing. About 30 seconds later, the cap starts flashing a light letting you know to stop and spit.
