Within the pages of this new book, historian S.H. Sharpe defines and describes seven Fundamental Principles, including Secret Closures; Reservoirs; Conduits; Liquid Substitutes; Displacement; Siphons; and Hydraulic and Pneumatic Control. The author traces hydraulics and pneumatics through history: From the early moving and speaking statues, inexhaustible vessels, unfillable basins, etc., to today's modern Lota Bowl; Foo Can, Multum in Parvo, Mermaid Illusion, and more. Also included in this massive work are two special appendices: (1) Scientific Magical Invention and Characterization and (2) What Happened to Psycho? This outstanding instructive work is a must. It contains techniques every magician should know. Printed and bound to match the previous works in this series. Hardbound, 116 pages.
