I recommend that if you want to do Mentalism don't clutter it with stage illusions. There are plenty of climatic routines you can do in a mind reading act that will play for a stage show. I recommend reading Bob Cassidy's "Fundamentals." There is a good segment in there on character developement. From an understanding of your character you determine your "Powers." Once you have those two things figured out then you can better weed out effects that don't work with your character.
Yes thank you I know that generally speaking it's not a good mix, however what I'm planning to do is actually very aligned with my character. I've been performing for 5 years so (or, looking at some examples of magicians who have been performing for years, I should say "and") I've got that stuff pretty much figured out
Although the effect I'm doing uses a trap door, it is a mentalism effect (...ish). Therefore, any alternative to a trapdoor has to be very "innocent" looking. I'm thinking a mirror under a table or something just to get a way out. Any ideas?
