First up on our list of must-haves for the Kensington Kinetic Sculpture Derby: cardboard tubes. These babies came from Arden Theatre Company. We think they’d make a great addition to your derby steed because they are visually striking, lightweight, and available in large quantities. But don’t take our word for it. Here are some inspirational images of projects made with cardboard tube remnants. Take a look at the projects below for inspiration [and click each picture for more information!].

Just… maybe don’t build this bike, ok? We DO want you to use reclaimed material, but… we also want you to win win win.
