**Title:** Unsuccessful Prank: Hair Chalk Fail
**Summary:**
* The host, "M", attempts to prank a sleeping person, Sophie, by using "magical" hair chalks to color her hair.
* M tests the chalks on a friend, Leone, but they don't work, revealing the hair is fake.
* Assuming the chalks will work on real hair, M tries to color Sophie's hair while she's sleeping.
* The prank largely fails: the chalks barely leave any color, and what little color is transferred is mostly on M's hands.
* Sophie wakes up to find her hair slightly, undesirably colored and confronts M about the failed prank.
* The video ends with M recommending viewers watch another video from the previous day.
