"Teleportation"?! That's a fancy word for good old "vanish", with the inevitable "re-appear"! I'm going to start using that...
Amusingly, if you have John Archer's "Educating Archer" (which you should, it's brilliant, and you can learn so much more from John than just the routines), he mentions his improvements and thoughts on the ring vanishing hanky, and actually describes trying out Richard Sanders' product (as a home made idea - the Any Ring hadn't come out yet) before dismissing it as not really working and moving on to further development! Which I found quite funny... I wonder if Richard Sanders owns that DVD
