Four years ago, we built a wall made out of cardboard tubes for the specific purpose of cordoning off a large area at Maker Faire for our chain reaction activity. We thought it would be just used for that one event, but was such a huge hit and worked so well that we kept reusing it again and again.
We brought the tube wall out on the museum floor for temporary tinkering studio events, framing out spaces for open makes, and to define our booth at every subsequent maker faire. The flexibility of shape and ability to change the length made it super convenient for us to prototype custom environments for different activities.
So after spiffing up the tube wall a bit, we put it right back to use as a temporary measure before getting more sturdy gates built by Al Bellevue (to be featured later on the blog) to close off the space during construction. We also are using the tube wall to set aside a dedicated area for workshops in the center of the Tinkering Studio.
