Innocent Smoker Sea Life CHOKING HAZARD (1)Not only can you see the danger of secondhand smoke with this model; you can collect it. This interactive display collects the pollutants in secondhand smoke from a cigarette smoked in the enclosed chamber. After an electric fan pulls smoke through a filter, the residue on the filter demonstrates the amount of tar a nonsmokers lungs absorb from someone elses cigarette. In this unit, the filter demonstrates the tar that would be absorbed by a child.
