Personally I wouldn't trust this guy as far as I could throw him!!..
His persona is that of a pleasant, kind and down to Earth type of helpful guy, and maybe he really IS that type of guy!!..BUT.
He used the very best advertising "Buzz word" Quantum in his video, Quantum Jumping

..
The point iam trying to make is that whenever "procedures" such as the 2 glass method arise, there is always the possibility that something evil can be transferred into your mind, without you ever being aware of it...
Back in the 1960s before we ever knew about professional Ouija boards, we used a glass to speak into, and cut out pieces of paper with the alphabet and numbers written onto them, and then placed them into a circle upon a table, with the glass in the centre of the circle...
Never try to use short cuts such as Ouija boards and Glass methods to make gains for yourselves, you just might get a lot more bad things happening to you, than what you ever thought possible!....Stay safe and be alert to a "Dark Side" of life..
