Richard Osterlind's Challenge Glass of Water production shares a similar methodology, but was independently conceived. Richard's inspiration was Dunninger's production of a glass from a cloth bag (was that an Al Baker effect?), which was likely inspired in turn by the egg bag. Richard wanted a method using an ungimmicked paper shopping bag which could be examined before the production. He came up with a very practical method, which has been featured on television by several, including Paul Daniels. It was originally published in THREE MIRACLE ROUTINES, a Jeff Busby publication and released on Richard's CHALLENGE MAGIC video and on one his Mind Mysteries DVDs. Great trick!
