Why it worked
The video likely worked due to its satisfying ASMR-like qualities, the visual appeal of the foaming action, and the unexpected combination of common household items creating a visually interesting result. The "Not your Norm Spirit Week" context also likely contributed to its reach.
Summary
A green sponge is placed in a sink. Micellar water, face wash, and toothpaste are sequentially poured and squeezed onto the sponge, creating a large amount of foam. The sponge is then repeatedly squeezed under running water, generating even more foam.
