Why it worked
The video uses a common "cutting a large item into many small items" trend, which is visually satisfying and surprising. The unexpected shift to a jail scenario with gold and money adds a dramatic and engaging element.
Summary
The video shows a person cutting a large watermelon into many small watermelons, then a large Pepsi bottle into many small Pepsi bottles, and finally a large lollipop into many small lollipops. The creator then appears to be in jail with gold bars and money, and is then apprehended by police.
