Have you ever stumbled into a corner of the internet and wonder "how did I get here?" Well that happened to me last month when I discovered the amazing mostlyharmlessarms.com and their custom built foam dart launchers. Seriously, they are mechanical wonders and very cool for adults and kids alike. I was inspired by their creations, and designed this Mini Cork Launcher. It operates on similar principles to those found on MHA: a piston pushes air through a tube and launches a projectile. However since I do not have any foam darts handy, I scaled mine up to launch wine corks. The artificial ones seem to work best, but experiment with what ever you have on hand.
I originally designed the plunger to use o-rings, but that never panned out, so I ended up gluing some 5mm thick foam to the end of the plunger and trimming it to size; works pretty well!
