Well, the spectator cannot put the item in any of the 8 tins he wishes, there is a cutting and
editing in the demo , you won’t understood till you see the whole performance, about the bottle caps
the method he teaches is not exactly as he performs, because i’m familliar with these specifics caps
of the eagle beer's, and he is using, i take a close look on them , by pausing the demo, screen
shooting and zooming in, he uses same idea as same as with the tins.plus the method and idea is a
very old school and not perfect and not 100% proof , in some performance it is a 50/50 .
