why are some "life hack" videos so stupid?

sometimes you can find people saying that you get cool stuff from doing stupid shit

I found a video that says if you leave a carrot in pepsi for a day it becomes stretchy and people already know ti doesn't work. I bet were gonna have some influencer go like "shove a finger up your ass and scream my name 5 times in the sink and you will get a super cool car!!"
