Practical Mental Effects has been lauded as the perfect accompaniment to Annemann's age-old classic. On the first three volumes, Richard took effects straight out of the book and used them to completely destroy a modern audience of college students.
On volume 4 Richard Osterlind and Jim Sisti return to the same school and do it again, but with many amplified versions of other Practical Mental Effects material. For most of these routines, Richard changed the workings and methods slightly (or sometimes very significantly) to make the effects more direct and streamlined. You will love his thinking!
