This is interesting because I haven't seen a question on Ouija boards before, plenty on other paranormal nonsense like astrology, psychics/mediums, Bermuda triangle etc. etc. so here goes.
First and foremost, they are a load of nonsense, they don't do what they caim they can do, and it's very easy to prove so.
First, what is a ouija board? The name is derived from the French and German word for 'yes', the board consists of the letters of the alphabet, numbers and usually the words 'yes' and 'no'.
One or more operators sit around the board each resting their fingers lightly on a planchette, which can move freely across the board.
It is said that 'spirits' cause the planchette to move over the board, spelling out messages etc.
The movement is actually due to the ideomotor effect, as in dowsing with rods or pendulums, this can be proven quite easily because 'IF THE OPERATORS ARE BLINDFOLDED, ONLY GIBBERISH IS PRODUCED'
I also read of an experiment where coded symbols or letters, replaced the conventional alphabet on the ouija board, in the room where the operators were sitting, and in the next room, out of sight of the operators, was a large notice board on the wall showing which letter of the alphabet was represented
by which symbol on the ouija board.
As would be expected, all the so called messages that were 'received' were total gibberish, or was it not possible for the 'spirits' to go from one room to the other to deciper the code?
Lastly, if there is anyone out there who thinks that he can prove ouija boards work , take the Randi $1,000,000 challenge sourced below, and before you make any excuses about not needing, or not doing it for the money, give it to Children in need, or any other worthwhile charity.
I welcome any comments, I never get any from my constant challenges to nonsense claims.
