SA GP G4 AIREEN – FICTION SMOKE

This project is about making smoke rings with a plastic bottle. When we hit  the bottle, a smoke ring will come out from the neck of the bottle. But the hot smoke can damage the plastic bottle when it is used over and over again, and it can also irritate our eyes and nose. So, we have to replace the smoke with another source that can be launched as a smoke ring without damaging the bottle nor our health: Mist.
