A typical rubber band airplane is maybe a foot long. Project Air took the idea of a rubber band-powered plane and supersized it to create a lightweight foam board and carbon fiber flyer with an 11-foot wingspan. The trickiest part was getting its eight propellers to all start at the same time.
Awesome Rubber Bands
It’s pretty easy to find toy airplanes that are powered by a rubber band. On the other hand coming up with something that replicates the dual rotor movements of a helicopter is more of a challenge. Maker Peter Sripol managed to create one. Download the 3D printed part designs on Thingiverse and watch the build video here.
Matthew Davis’ Arcus is a 3D-printable rubber band gatling gun. Its unorthodox appearance is more than just for show. Unlike most rubber band guns, the Arcus uses the energy from the rubber bands being shot out to rotate the barrels and continue the barrage. Grab the 3D models and directions on Instructables.
This wouldn’t be the first time we saw a machine gun that fires rubber bands, but this time out, we’ve got The Q showing us step-by-step how he built his from cardboard, wood, string, hot glue, and popsicle sticks. If you’d rather not DIY, you can buy a wood one here.
The next time you launch a rubber band, watch this video as a reminder of the manual labor that goes into the production of these stretchy office supplies, which start as the extract of a rubber tree, which is dyed, dipped onto rods, peeled into tubes, then cut into thin slices.
