Doing proof of concept for vortex tunnel and finalizing measurements. We are a go! It will be 28 feet long and much improved design over my first attempt four years ago which did not sufficiently seal out wind. Vortex is created with green ring projection, not laser. The goal is to fully position the green ring in the 7 foot opening/entrance. I will use poly sheeting, not tarp.
