Heres a cool one i wish i had the money to do, get your guitar, grab the neck, hold the body with your palm, and throw it out a window a few storys up. once it makes contact with the pavment, it should cause alot of Vibrato. now quickly get in your car, go to the guitar store and buy your self one without a Floyd rose.

(just kidding, but my they can be a pain in the butt sometimes.)
