Though originally invented by a couple of teenage boys to torture the noses of their adversaries, the gag product Liquid Ass Spray has surpassed its original prank purpose. It's sometimes used in medical simulation, a training technique that gives medical students the experience of working on a real patient without the risks. In the most vivid simulations, technicians must create fake blood, urine, vomit, and feces to be released from medical mannequins at the right moment. In an article for Vice, medical simulation technician David Matney described the way he mixed Liquid Ass Spray with chocolate pudding, applesauce, canned corn, and peanuts to replicate feces in his simulations. Though this all may sound bizarre, it's doing patients a service.
Research shows that medical simulations help students better understand symptoms, know how to deal with complications, and learn to use medical tools so they're better equipped when faced with a real human patient.
