The Smokey Sue Smokes for Two Model is a teaching aid that demonstrates the adverse effects on a fetus that results from a mother smoking cigarettes. The model demonstates tar collecting around Sue's fetus with each cigarette she smokes during pregnancy. As the tar builds up around the gaunt fetal model it gradually tints the clear fetal environment a sickly shade of amber. Sue may not be able to think for herself but she prompts others to do plenty of thinking. This model requires real cigarettes (not included) and the jar and fetus are easy to clean. Measures 5" x 14" x 5"
