Didgeridoo Vibrations

Well, this was discovered by some friends with my didgeridoo (a traditional Australian Aboriginal instrument). Basicly someone plays the didgeridoo and someone else puts his genital region at the other end (covered by pants) and feels the vibrations. It feels so cool. If ya don't have a didge' try some poly pipe or the centre of aluminium foil rolls and you play it. Blow like a trumpet buzzing your lips. The other good vibration feeling I have found is to play video games with a shaking controller and put the controller in your crotch. It is so good.
