The purpose of the project was to devise a garlic peeler in order to compare the efficiency of peeling a garlic with a garlic peeler and the efficiency of peeling one by hand. To invent the garlic peeler, we used the principle of rotation . The device was fabricated using a washing machine swivel plate, a stainless steel pot, a timing belt, and a metal bar. In the experiment, the garlic peeling was divided into three phases, (one for a small, one for a middle, and one for a large garlic). After that, a 1 minute timer timed the peeling of a 28 gram garlic, a 38 gram garlic, and a 51 gram garlic,
