Very good DVD instructions and definitely has a
"wow" factor to it.
For any trick that
requires double sided tape (this one, but use regular tape for the card to the window)get UGlu
patches. I found them at a CVS drugstore on the "as seen on TV" shelf. You'll be amazed at how
sticky the tiny square is. It's clear, so it would be perfect for "card on ceiling" and for stealing
something from the side of your pants.
