i realy feel like shiting onto a fan just to see what happens... and how long i would leave the mess before cleaning it...
They tested this on mythbusters and when the shit hits the fan it goes EVERYWHERE! You probably won't even find all the shit. There will be specs of unfound shit in your place for years to come.
Take the cage off and sit directly on the fan. Then we can vote on whether you will spin, or tear your ass to shreds.
Really I think it has to be a ceiling fan for it to work. I got an olddddd fan, kinda like the one Dado posted and it has virtually no cage guard on it; was throwing things at it last year and it would kind of just slap the object down onto the table.
Go up into your attic. Cut a hole in the ceiling drywall about 8 inches out from the ceiling fan mounting/electrical box. Place a milk crate with a hole cut on the opposite of the open side and place above the hole cut in ceiling. Place high speed still frame camer in room angled at ceiling fan to capture epicness. Place ass on milk crate and squeeze!
