::SIP THE BUBBLY::
One of the most enthralling parts of the Science Museum of Minnesota is the art piece called "Pipedream." The bubbles are let out of air valves at the bottom of the clear tubes, and they combine to form patterns as they rise to the top of the lobby's ceiling. I could watch this for hours, but I had to settle for ten minutes. I saw zigzags, a smiley face, and amazing long bubble-segments that collapsed on themselves to form even huger lines. Bruce Shapiro knows his stuff. Here's a picture I took:
