Three demonstrations in one model.

• See the results of active, second-hand, and third-hand smoking
• All three effects are visible during first experiment
• Easy to clean and observe

Smoking is one of the leading preventable causes of death worldwide, killing several million people each year, from which 15% are the result of non-smokers being exposed to second-hand smoke. Third-hand smoke, when chemical residuals of cigarette smoke adhere on our close environment (walls, carpets, sofa etc.), has a higher risk on infants than adults as they crawl and touch everything, and due to that can swallow the hazardous chemicals.

This new, absolutely unique, yet cost-effective and user-friendly 3-in-1 smoking model clearly and dramatically demonstrates the results of active, passive, and third-hand smoking. The tar that accumulates in the lungs when a cigarette is smoked is collected on a half circular filter. The tar which would reach the lung of a passive smoker can be seen on another half circular filter. Effects of third-hand smoking can be observed on the wall of the transparent cylinder. The chemical residue of the tobacco smoke can be collected using a cotton bud.
