I learned this trick from a mechanic

The video uses a common object (car mirror) in an unexpected way to create a visually interesting and satisfying process, making it highly shareable as a 'life hack'.

The video demonstrates a life hack for car side mirrors. The creator uses rubber bands and tape to create a grid on the mirror, then draws tally marks on the tape to track something. Finally, they use clothespins to hold the tape in place.
