I saw one of these built by what I would call the love child of Einstein and Macgyver on a BBC show called Bang goes the theory. He used a fire engine pumper truck to supply the water for the thrust. It's on youtube (https://www.youtube.com/watch?v=ZFjih5bFfK8) and other things like a votex canon. The peanut brittle rocket engine seems not to be on there anymore. He claims to have made it quite cheaply
John, It's not a myth. It is real. I saw this a few years back on a cable tv technology show. You can buy one if you have lots of extra money sitting around.

In early times, in bigger boats, people use to climb on the pole and see distant view with mono-cular.
I am not kidding, even in todays time this would help a lot, I think people can imagin, how.
