The judging of the 2021 U.S. Crystal Growing Competition (USCGC) was hosted this year at Texas A&M University. Founded by Jason Benedict, UB associate professor of chemistry, the contest invites K-12 students and educators to grow the largest and most impressive crystals with aluminum potassium sulfate (alum), a nontoxic chemical used in water purification. A full list of winners will be posted on the contest website. Photos: Texas A&M Science
