The not
examinable part, I fix with a Max Maven idea. After the participant places the billet in the
envelope. I ask them to rip a long piece of masking tape (while I p***). Then I fold the envelope
and then I go around the whole envelop both horizontally and vertically with the tape (now it's
examinable and the participant can hold it). It has to be torn apart to reveal the billet.
