Why it worked
The video likely performed well due to its visually engaging and satisfying time-lapse of plant growth, combined with the unexpected and somewhat surreal starting point of a melting watermelon slice. The use of popular hashtags also contributed to its discoverability.
Summary
The video shows a time-lapse of a watermelon seed growing into a plant. It begins with a watermelon slice melting on the ground, then shows the seed germinating and developing roots, followed by a sprout emerging and growing into a plant with leaves and eventually flowers and small watermelons. The entire process is shown against a backdrop of cars driving on a highway.
