Brings the card warp into the real world. Can be done impromptu, but shouldn't be a problem to carry
the gimmick & a couple of preped ones with you. If turning them inside out as instructed is a
problem, I've found you can separate it at the glue point, turn it, & reglue it. Prepared ahead of
time. Easier & it ends up flatter. If doing it in the coffee shop, then do as he instructed. You'll
like this.
