take the motor out of a vacuum, preferably The Boss (yellow) and take off the gadgets (fans, ect.) and stick it in a locker and call in a bomb threat. Pretty cool...of course it doesn't blow up though.

LAME

thats the gayest thing i ever heard. Why not just call in the bomb threat???? i doubt that the fan will make any difference considering its not spinning or making any convincing type of beeping and or sounds that would scare someone.

you take the fan off so it looks more convincing if they find it. and having the device just prolongs the threat.

dont forget to wear your gloves
and dont get seen with it ever
