Turbine
exhale
i can inhale air
It flows downwards because it is cold and cold air sinkse. The most important reason why it flows downwards is that dry ice is made of CO2 / carbon dioxide which = 1.5 times heavier than the air that we inhale.
Air enters the body when you inhale (Breathe in) air enters through the mouth and into the lungs. and then exhale (Breathe out) carbon dioxide (CO2)
An airpipe is a pipe or tube through which air flows.
