Can Breathing Through a Tube Create Powerful Force for Tasks?

[ericwatts214]

How much force(air pressure would the process in this video take?



Could it be produced or magnified to work using breathing through a tube? To create the seal?

Depends what you want to do. I've seen a device that converts a felt tip pen into a crude spray gun by blowing through a tube at right angles to the pen nib. It draws the ink out of the pen and blows it onto the paper.

You would have a hard time emptying a fish pond using just your lungs to blow down a pipe.
