[edit] "E pur si muove!"

I'm pretty sure that I read somewhere that atleast one very sensitive experiment showed that the feynman sprinkler does actually turn- but the effect is very small. I don't have a ref though.WolfKeeper 15:28, 8 April 2006 (UTC)

This is probably due to friction, a property which is ignored in the thought experiment. -- Rmrfstar 18:39, 8 April 2006 (UTC)

Probably something like that, or there's a bit of angular momentum being transfered due to twisting in the air leaving the pipe. The University of Maryland experiment is actually mentioned in 'An elementary treatment of the reverse sprinkler' reference, but I was unable to currently locate the video on the web; although I have seen it previously, if anyone finds it, please add it as a reference.WolfKeeper 22:23, 21 July 2006 (UTC)
