'Snowball chamber' helps researchers use supercooled water to search for dark matter

(American Physical Society) After watching YouTube videos of people supercooling water in a bottle and then triggering it to freeze by banging it, something about this concept solidified for Matthew M. Szydagis, especially when he saw it again during the Disney movie 'Frozen.' During the 2019 American Physical Society April Meeting in Denver, Szydagis will describe how this inspired him to explore whether a subatomic particle like dark matter can trigger the freezing of supercooled water.
