Jonah Jacobstein, 5, of Ithaca, N.Y., tries making music with a didgeridoo Tuesday afternoon in Wailuku. Jonah and brother Eli, 8, each was given a turn by the the instrument's owner, Chava Doppio (center) of Oklahoma. Looking on is Moon Honey. "You've got to relax your lips," Doppio said. "It just takes a lot of practice." The Jacobstein boys managed to get a few notes out of the didgeridoo, but not enough that passers-by on Market Street could mistake them for Aborigines from Australia.
