Keep hands clean and stay healthy with this neat one-touch multisensory timer that provides both auditory and visual cues to help kids know how long to wash their hands! Kids simply tap the button, scrub their hands while the light is on, and begin rinsing when the light goes off and the timer beeps. This neat hand washing timer is especially helpful during this time when thorough handwashing is so important! This smart 4" sensory timer lasts 23 seconds: 3 seconds for "getting ready" and 20 seconds for actual washing. Requires 2 "AAA" batteries (not included). Awesome!
