I will be filming some more on the return flow discovery shortly but feel t= his is an important experiment that not only addresses cohesion in water bu= t gives a clear understanding of bulk flow rates observed in trees which ca= n never be addressed using the current accepted literature or the more rece= nt inclusion of the tension theory. I would very much appreciate any thoughts or questions on the video or the = theory which the video and experiment was designed to illustrate. And if yo= u could leave a comment or question on metacafe it will undoubtedly help to= stimulate more interest and accelerate this debate to a conclusion.
