My favorite method was featured in the Gods Must be Crazy film.
When the guys wouldn't talk they tossed them blindfolded out of a chopper. The chopper was hovering a couple feet off the ground.
I have experienced a couple of these, blindfolded with a land rover pulled right next to your head, everytime the engine was revved the spare wheel was run againat you
Also blindfold when water bottles are emptied over you and a petrol soaked rag is held under your nose whilst people play with striking matches. Both techniques focus the mind
