Objects in motion will stay in motion, until a comedic force acts upon them. The Gizmo Guys — Allan Jacobs and Barrett Felker — have won international juggling competitions, taught at top circus schools and appeared on television. They are featured in this year’s Spot — The Hancher Family Arts Adventure. They’ll also be at: Iowa Children’s Museum at Coral Ridge Mall, workshop at 6:30 p.m. Friday and mini-performance at 2 p.m. Saturday; and the Iowa City Farmers Market, 10 a.m. Saturday.
