me not worthy, that`s cool-cooltubes are good where heat buildup is an issue-but they (the comercial units) reflect poorly, atleast compared to a adjust-a-wing or a diamond.
Jorge Cervantes does something similar in vol.2 of his latest movie-but
outdoors-he gets a big square water jug and punches a tiny hole in
the bottom corner, so it irrigates one drop at a time.so if you want
to do a guerilla show it`s a good tip
