Let's wash hands properly! WHO states that the right way to wash your hands is to "scrub your hands for at least 20 seconds", which takes about as long as singing "Happy Birthday" twice. Handwash DJ enhances the appropriate hand wash experience by playing a random song on Spotify for exactly 20 seconds. Before you wash your hands, say "Okay Google, Hand Wash DJ", and scrub your hands until the song finishes. #SafeHands
