This is a great schlieren video! It is impressive how you were able to see differences in air density with compressed air in such a small reference frame.
Cool video Hank! I think that it is interesting how the layer near the bottle oscillates between being close to the bottle and further away from the bottle. Do you think that the oscillations form because of slight changes in the direction of the incoming compressed air?
