“It appears big brother is watching this garbage disposal area but closer inspection reveals that the camera is a cleverly crafted replica made from a plastic bottle wrapped in black duct tape, sporting two drawing pins and with an old stereo cord added to complete the effect. I chuckle every time I pass partly at the fact that its not fooling anybody and partly at the fact that someone crafted and installed the device.” – courtesy of Byron Kidd

Cigarette butt disposal unit constructed from used oil can, wire, wood, tape, and PET bottle. An open-bottomed (to prevent rainwater collecting in the bottom) receptacle is fashioned from a used oil can nailed/screwed to a wooden stake and painted red. The receptacle is attached to the signpost with duct tape or wire. A PET bottle filled with water is placed inside the receptacle for safe and semi-odorless cigarette butt disposal. To empty the disposal units (3 in the immediate vicinity) one has only to walk around, pick up the PET bottles, and pour the contents into the rubbish (or down the drain, or wherever…). Signage is made of laminated computer print-out.
