The idea is so simple you wonder why no one thought of it
before.Crystals growing near the bottom of a beaker are subject to
convection,but it is much quieter near the top of the beaker.In that case, why
not just let them grow hanging in the beaker?Well, the idea was there for the
taking, and that is exactly what Elias Vlieg and his team from Radboud
University Nijmegen have done.Their work will be published in this month's
edition of Crystal Growth & Design.
