Why it worked
The video likely worked due to its simple, practical demonstration of a DIY solution to a common problem (phone stability or viewing angle), presented in a visually engaging, step-by-step format.
Summary
The video shows a phone being used as a level, displaying angles from 10 degrees down to 0 degrees. It then transitions to a person using tools to bend and shape a piece of wire, seemingly to create a stand or holder for the phone.
