I'm curious as to what is actually used to write on the spectators arm. I don't mean the gimmick that's used, but the "ink". Does it wash off easily?
Is there any restriction with the letters/numbers that can be used to perform Tagged? Can pictures be used also?
I noticed that white and black "ink" was used on the spectators. Can any color be used?
Does an effect have to be performed prior to this for the purpose of whatever set-up may be required? Such as, does it need to be routined with another effect(s) to be able to accomplish the outcome?
Does the reveal have to be on the spectator's forearm? Or can it be done in other areas, such as their hand?
