1F6AD

This video likely performed well due to its extreme brevity and the satisfying visual of typing a specific code that results in an emoji, combined with the ASMR-like sound of keyboard typing, which appeals to a niche audience.

The video shows a person holding a "no smoking" sign and then typing "1F6AD" on a white keyboard. The sequence is very short and appears to be demonstrating a keyboard shortcut or emoji input.
