“Witch Hand” is essentially a “Guess Which Hand It’s In” plot but with a spell being cast on the participant.

As long as the spell is cast, the participant can always correctly guess which of the performer’s hand has a silver pentagram in it.

Test conditions and challenges continue to mount, but while under the spell, the participant always knows. They don’t know how they know either…but they know, somehow.

That is, they always know until the spell is broken – in which case they are no longer able to correctly guess. They will continue to miss and guess incorrectly each time once the spell is broken.

There is a final surprise moment with a message too, if you so wish. You don’t need to do this last bit, but it is a great time to add a final kick.

Props are required but you could use a copper/silver coin or any copper/silver type item for a similar effect.
