THE WORKING
The twenty-second smiley timer is a timer equipped with a station that houses any liquid hand wash soap or a bar soap in your hand washing space. It activates when the user extends their hands to use the hand wash soap.
The initial position of the timer is in the form of a "SAD SMILEY FACE". On being activated by sensing the user's hands, the "sad smiley face" starts rotating for a course of twenty seconds.
On approaching the twentieth second, the timer is now with a "HAPPY SMILEY FACE" and initiates the buzzer to indicate the user to wash their hands with water and indicating them to get rid of the soap.
Here's a brief working of the device.
