Soappy is a hand sanitizer printer designed to encourage kids to foster the habit of washing hands. Most kids don't like to wash their hands due to the boring and tedious handwashing process. Soappy makes hand washing an attractive game by printing various hand sanitizer patterns. Kids can choose their favorite patterns and get them printed on their hands. Besides, Soappy provides different groups of patterns according to how dirty the hands are, which means the more dirt and germs the hands have, the more complex the patterns are, and the more hand sanitizer they contain.
