Brilliant! Vaille Swenson, a senior biology major at Dakota State University, figured out that an Instant Pot (which costs about $150) is as good at killing microbes and sterilizing equipment as an industrial autoclave (which costs thousands of dollars). She experimented with different microbes and different pressure cookers and published her results in the Public Library of Science.
