Why it worked
The video likely worked due to its visually appealing and somewhat mysterious "life hack" format, combined with the unexpected use of a phone's flashlight to create an aesthetic glowing effect with the jarred contents. The use of trending audio and the intriguing visual presentation likely contributed to its shareability.
Summary
The video shows someone preparing a jar of what appears to be red caviar and butter. They rinse the mixture in a sieve, then add water to the jar, and finally seal it with a lid. The jar is then placed on a phone, and the phone's flashlight is used to illuminate the jar, creating a glowing effect.
