Highest prize offered for a scientific proof of paranormal ability

The James Randi Educational Foundation Million Dollar Paranormal Challenge was first offered in 1968 by American magician and sceptic James Randi, initially as a prize of 100 US dollars. Over time the prize money has increased to one million US dollars, which will be awarded to the first group to scientifically prove the existence of paranormal or supernatural abilities. Between 1997 and 2005 some 360 applicants were made. No one has yet been awarded the prize.
