USB-powered ashtray

Not all offices are are completely smoke-free environments, so it would be wise to purchase this USB-powered ashtray for the resident walking chimney in the office. This device comes in the shape of a small blue car and opens up halfway to reveal an ashtray. When it is plugged into any available USB port, a fan will begin to turn, sucking any smoke upwards and forcing it through a carbon filter should there be a cigarette in the vicinity. Alternatively, it can run on a couple of AA batteries should you be unable to find any free USB ports around. This nifty little gadget costs $22.
