Pick a card . . . Learning all of the parts of the anatomy and how they work is often an overwhelming task for medical students. While some may credit a miracle with helping them finally memorize the names and functions of the body's hundreds of parts, others simply rely on magic. Dr. Benjamin Krevsky, associate chairman of Temple's gastroenterology section, is a magician whose students remember the fundamentals of constipation because of an illusion using three cups of water. After Krevsky moves those cups around a bit, students are amazed to see that the water in the third cup has mysteriously disappeared.
Water goes in but nothing comes out.
I've had doctors come up to me years after their GI pathophysiology course to tell me that they remember a specific lecture because of a magic trick I did for them. Krevsky took up performing magic tricks while attending medical school at the University of Cincinnati. It was primarily a hobby in the beginning, but has continued to be useful to him professionally. He uses magic to describe various illnesses and their treatments and to liven up lectures that he participates in as the director of gastrointestinal endoscopy. He uses silk scarves and fire to demonstrate the color change that occurs in a patient with Barrett's Esophagus following laser treatment.
