Short and sweet! I like the principle Michael John has found - it's nothing weird, it's practical,
it doesnt take a lot to make this feel truly improvised - I had the necessary materials on hand, and
yup. It works. There are constraints and specific conditions to it, but angles are great and you
really do end clean and your spectator can really take the coin in the bottle as a souvenir.
Teaching is clear and deliberate, and he includes some equally good alternate presentations. Worth
$20? I think so.
