I dimly recall seeing that in a movie theater in the early 1970s. Great short film - I remember a scene with a guy with a garden hose spraying it in slow motion to wipe out bugs in the garden. I'd like to see it again too.
I think this one came later; but I seem to recall that he did several things on plant life.
