US Crystal Growing (USCGC) 2026
Rated Advanced, The US Crystal Growing Competition asks students to grow and submit a single alum crystal for national judging on size, quality and overall result. K–12 students may enter through a classroom or household, with limits on starting material and the number of crystals submitted. Success depends on patient experimental control, careful observation and repeated adjustment over several weeks rather than a one-day test.
