The Fun Theory

Most of the people who smoke don't really take care where they throw their cigarette buds. Although there are enough public ashtrays and especially downtown and in pedestrian zones, people still throw their buds on the street. Our idea is to get their attention with lights and sound, by installing a heat sensor on the ashtray plate and connecting it to LED lights formed in the shape of fireworks, and a small speaker. As the cigarette touches the ashtray, the heat sensor will send trigger the lights, and the sound. This way, we will not only make the ashtrays more obvious, but also provide a little fun for everyone, and hopefully keep the streets a little bit cleaner.
