For example, the in vitro method which consists of tests using human cells and tissues. Another example would be “Corrositex which uses a biomembrane and chemical sensing system that changes color when in contact with corrosive substances. In some cases, this could replace the use of rabbits in corrosivity research” (AAVS, 2014, Product Testing). Non-animal tests are widely available, more informative, cheaper, and faster than animal tests. Sophisticated computer software and realistic human simulators are used in schools and colleges to teach basic and advanced biological principles and medical procedures. “Today, one can even become a certified surgeon without harming any animals, and experience with animal dissection and live animal testing is not required or expected of those entering medical school” (PETA, 2014, Animals Used in Education). With alternatives, experimenters don't just have one chance to test something, they can do it multiple times without causing any harm to the animals or
