Levitating Beads

"Earth Unplugged showed how a bead chain can appear to levitate as one end falls out of a beaker."

"As it turns out, there’s no magic involved, but rather a fascinating scientific explanation. Once some beads are dropped out of the container, their momentum pulls more beads along with them, and the limited flexibility of the chain causes it to assume shapes that appear to defy gravity as it falls."
