Actually I've been using this at work EVERY DAY since purchase, this is my method and YES, for once it's FULLY examinable.
I take the five symbols for ESP, six billets for each symbol (30 pieces) and place my prediction (example I've used is wavy lines and square) sitting on a painting at my desk. I explain the symbols, what they represent and the exact number of billets per symbol in the glass. Two spectators cover and shake the glass to "empower" the billets. Cleanly I dump one billet to each person, if two drop they fairly choose which they want.
After they reveal their paper's content I point at the painting that's a good distance away that I went NOWHERE near and explain two days prior I saw a vision, two things that I couldn't figure out... Until now... I have another person walk over and open the predictions and BAM!!! Match!!!
I then dare them (which they jump up to do immediately) to count each ball revealing 28 remaining billets... The kicker... They are ALL BLANK!!!
They literally stand there dumbfounded.
Dependent on your performance... Completely examinable.
