Satisfying!!!

Oddly satisfying videos are internet videos that portray repetitive events or actions that viewers find pleasing. Common subjects of oddly satisfying videos include domino shows, parlor tricks,[1] slime, hydraulic presses,[2] soap cutting, and paint mixing.[3] Viewers may watch oddly satisfying videos as a form of escapism, and some oddly satisfying videos may bring about ASMR.[3][2]

Glitter slime is commonly featured in satisfying videos.
The term emerged on the internet forum Reddit after the /r/oddlysatisfying subreddit was established in 2013.[3] Oddly satisfying videos are now widespread on online video platforms such as YouTube and Instagram.[1] Wired UK called slime, a common feature of oddly satisfying videos, the "biggest DIY trend of 2017, even causing a national shortage of glue in the US."[3] In 2021, The Guardian wrote that "the pandemic, coupled with an increasingly chaotic news cycle, has us striving towards the ultimate #smoothbrain state – meaning there’s a global audience regularly seeking out the oddly satisfying, and a huge wave of content creators actively manufacturing it."
