I performed this for a crowd of about 50 recently and it got a big reaction. A few days earlier, I
did it for a much smaller group and they also loved it. The working of it is simple enough and it
allows you to lean into the performance a bit. Depending on spectator response, there might need to
be a slight bit of hedging at the end of the routine, but even this can work to your advantage,
making it seem like you are making the selection even harder to engineer. It engages the crowd well
and it's fun to perform, so if you like the concept in the trailer, you'll like this trick.
