The Physics Teacher
This month's cover shows shows hot water being flung from a cup, and forming a dramatic arc of ice crystals in the -20 oC air. This photograph was taken at the Bashang Grassland in China by Luanyin Huang of The International Academy of Guangzhou No. 6 Secondary School, and is one of the recent winners in the 2018 AAPT High School Physics Photo Contest.
