This experiment uses 400 cigarettes and simulates a 20-pack-per-month habit. For the traditional pack-a-day smoker, this is low.

Note from the producer and creator of this project:
"During running this experiment, the speed and air pressure of the machine was very high and strong, made it difficult to stop and catch some of the filters before burning a cigarette up to the end. Some filters burned down and sucked down into the water inside the bottle, what you see at the end of the video, the black substance, is tar mixed with the ashes of burned filters, that is what made it hard and look dry after boiling. The pure tar is sticky and usually remains softer than what you saw in this video."
