This is a motion activated quit smoking novelty ashtray. A fun way to help people quit smoking. This ashtray looks like a lung, and as you put your cigarette in it, it starts coughing and screaming. Great novelty gift for the smoker in your life. Anyone who's ever tried to give up smoking will know it's not exactly fun, and now matter how much your friends and family encourage you, the temptation can be too much. And what about those times when you're home alone, bored and the cigarettes are calling - who's going to stop you giving in then? Well now your ashtray will! Very cool gadget, works really well. Requires 2 AA batteries (not included). This item makes a great gift.
