Constable Julie smoking!

This is a movie of Julie smoking! Although...not real smoking. She is conducting an experiment to see what smoking does to your lungs. The 'lung' is a plastic drink bottle. The 'windpipe' is a narrow tube, with a cotton bud at one end and a cigarette at the other. When the cigarette was lit, Julie squeezes the bottle to imitate breathing. It is amazing how much smoke enters the lungs just from one cigarette; after just a few breaths, we couldn't see through the bottle! Worst of all, when the tube was removed from the bottle, the cotton bud was a disgusting yellow colour. Watch this video to find out more...
