This is a fun little routine that will teach you a couple of basic coin sleights. There are no
gimmicks involved. You're just doing a palms and switches.
The second switch is probably
the move that will take the most practice, in order to get the proper timing down. It's not very
difficult, but you need to be able to do it very smoothly in order for the illusion to work.
You also end reasonably clean, because when the spectator discovers that both holes are now in
one washer, all the initial heat will be on the washers. This gives you plenty of misdirection to
dump the one you're holding.
Besides this basic routine, there is also an extended routine
that includes more transformations and introduces some more handling elements. This is also good
stuff and well-taught. Once you've got the basic routine down, definitely move on to this one.
