The Davidson Institute of Science Education’s International Physics Tournament challenges teams of high school students from around the world to design impenetrable safes. Each spring, the teams travel to the Weizmann campus in Israel, where they compete to unlock one another’s safes by solving the underlying physics riddles. On March 20-21, 2018, six teams—hailing from the Atlanta Jewish Academy in Atlanta, GA; Bruriah High School in Elizabeth, NJ; Green Valley High School in Henderson, NV; the Gregory School in Tucson, AZ; the Emery/Weiner School in Houston, TX; and Rancho High School in Las Vegas, NV—represented the United States at the 23rd annual competition. The American students joined other teams from countries such as England, Argentina, Romania, Canada, and Angola.
