Why it worked
The video likely performed well due to its satisfying visual simulation, the use of popular meme sounds (implied by the on-screen text), and its short, engaging format suitable for TikTok.
Summary
The video shows a simulation of colored balls falling into an hourglass shape. The balls change color from yellow to green as they fall and fill the hourglass, creating a visual effect. The text "guess the meme sound" is displayed on the screen.
