BUFFALO, N.Y. — From chocolate to snowflakes to salt, crystals are everywhere in our daily lives.
This fall, kids and teens across the country can grow their own big, sparkly crystals as part of the U.S. Crystal Growing Competition, founded by a University at Buffalo chemistry professor and organized by professional chemists across the nation.
“There is something almost magical about growing a large crystal and holding it in your hands,” says contest founder Jason Benedict, PhD, associate professor of chemistry in the UB College of Arts and Sciences.
“One super awesome thing about growing crystals and participating in the competition? Kids can do this at home or at school,” he adds.

Good alum crystals are colorless, transparent and octahedral. They sparkle when they catch the light.
Growing a great crystal isn’t easy: Go too fast, and you could see imperfections like occlusions or jagged edges (think rock candy). Go too slow, and you’ll end up with a miniscule crystal. Testing different techniques is all part of the fun, Benedict says.
Big things are happening! UB chemist Jason Benedict, founder of the U.S. Crystal Growing Competition, shows off an enormous alum crystal. If you sign up for the contest, your crystal won't get this big (for the purposes of competition, growing time and the amount of crystal-growing material allowed are restricted). But your crystal could be just as beautiful and sparkly, and hopefully you'll have lots of fun! Credit: Douglas Levere / University at Buffalo
The contest’s organizers — known as the Crystallites — include Jason Benedict and Tasha Benedict at UB; Karah Knope, PhD, at Georgetown University; Michael Nippe, PhD, at Texas A&M University; Jeff Rack, PhD, at the University of New Mexico; and Fernando Uribe-Romo, PhD, at the University of Central Florida.
The U.S. Crystal Growing Competition is sponsored by the American Crystallographic Association (which is based in Buffalo); the U.S. National Science Foundation; VWR and Ward’s Science; the UB Department of Chemistry; Georgetown University Department of Chemistry; the Texas A&M Department of Chemistry; the University of Central Florida Department of Chemistry; the University of New Mexico Department of Chemistry and Chemical Biology; the University of Chicago Pritzker School of Molecular Engineering; the Western New York section of the American Chemical Society; Bruker; Krackeler Scientific; Rigaku; and individuals who have made donations.
