SURPRISE! They NEVER get to the 20 second mark. No matter if they sing Happy Birthday, Count, recite a poem or anything else – unless there is an actual timer involved, it’s just not happening.
Belinda got a little timer and stuck it to the mirror. She instructed everyone to set the timer to wash their hands – EPIC FAIL!
If they remembered to set the timer (not very often), the process went like this: Set timer, Open Tap (1-2 Seconds), get soap (3-5 Seconds), Actually wash hands (12-13 seconds), Timer beeps, rinse hands.
That is when she came up with the idea to build a timer into a soap dispenser – this solves all the problems! She rigged a normal soap dispenser with a makeshift timer to test the concept and immediately noticed an improvement.
As soon as the kids squirt the soap in their hands the timer starts and within a few days they were conditioned to wait for the “Beep” sound before rinsing. Especially since mom made them go back and do it again every time they walked out of the bathroom before the beep!
