Go ahead, make my day. Or make something else at the Science Museum's "Make: Day."

Tinkerers, artists, inventors — and other do-it-yourselfers — get their own day Saturday (March 14) at the Science Museum of Minnesota in St. Paul.

"Make: Day" is billed as a celebration of creativity and ingenuity. It runs from 10 a.m. to 3 p.m. and features all kinds of wacky and wonderful inventions from local artists, engineers and inventors. Along with exhibits there'll be hands-on activities to get the creative juices flowing.

On display will be unusual musical instruments from Tim Kaiser, and the drumming and pounding percussion of oil drums and hubcaps, grinders and gears, of Savage Aural Hotbed.

The St. Thomas Academy experimental-vehicle team will show off its work, along with the Career Pathways Academy robotics team.

It's bound to be a cornucopia of Rube Goldbergmania. (If they can invent contraptions, I can invent words.)
