10 ft circumference 16 ft long rotating Vortex Tunnel. Patrons walk thru the tunnel that will disorient them completely with a dizzying effect. A gigantic project that has been designed that I am about to begin building. Parts and materials will be cost approx. $3000. I estimate about 200 hours of construction. The Tunnel will be steel construction done by a local machine shop. The bridge and the frame will be wood construction. it will balance on six amx bicycle wheels and will be powered by a chain driven gear reduction electric motor. The tunnel will be covered by a light weight nylon material painted inside with psychedelic patterned black light fluorescent paint.
