Bollocks. The stuff done in those videos is cheap magic. Notice how you aren't afforded a good look at the bottom of the bucket? My theory: tape a mousetrap to the bottom of the bucket and spray paint it all black to blend in with the colour of the bucket. Soak a large iodine chrystal in ammonia, jamb it in the trigger mechanism,, set the trigger, gently put a little bit of water in the bucket and wait a couple of minutes for the ammonia to flash off. What's left is an unstable crystal that explodes, triggering the moustrap that flips the bucket onto its side and spills its contents. Voila. Instant poltergeist. High school chemistry and physics, but there will be a number of different approaches to essentially the same problem: how to get a bucket to tip over predictably without using strings. Tell him to do the experiment over again with a full bucket of water and a white bucket, and show us the bottom. That would be more difficult to do (but still doable with a little more sophistication).
If this joker really had a legitimate paranormal phenomenon that is so predictable he can set up cameras and conditions under which to catch it all on video, all he needs to do is get hold of the folks at Randi to claim his $1,000,000 prize.

sinis, have you ever watched that BBC documentary series called The Nazis: A warning from history? It is a really compelling look at the rise of Adolf Hitler and his lot. As far as documentaries go it's an eye opener. It succeeds in making you understand how it is a psychopath like Hitler could ever have come to power in Germany and, more importantly, how the poplulace naively made themselves complicit in the tragedy that followed. Such hatred and insanity has neither historical precedent nor equal. Have you watched it? I seriously doubt it because if you have watched it and you still hold onto the Eagle and Swastika of the Third Reich as your avatar, it says something about you.
