Why it worked
The video uses a common visual gag (dropping an object into a carbonated drink to make it fizz) and then transitions to a visually engaging display of animated effects on a phone screen, which likely captured viewer attention.
Summary
The video shows a bottle of Fanta being opened, with a small white object being dropped into it. The bottle then fizzes and bubbles. The video then transitions to a phone screen displaying a TikTok video with animated characters, and then shows various effects being created on the phone screen by touching it.
