I'm afraid you're wrong. It very much is magic.
A lot of dowsers were asked what they could dowse for, and moving water seemed to be a very common answer, so a test was set up to see if they could detect moving water.

The water has to be moving or charged for metal dousing rods to work, they will not work on a bottle of water.
about 100 dowsers contacted the GWUP. In the following months, we tried to gain a clear impression of what kind of abilities were being claimed by means of a series of letters and a questionnaire. It turned out that a majority of prospective dowsers claimed the ability to locate running water in pipes. We therefore decided in the spring of 1990 to base the dowsing experiments primarily on this form of test. In addition, some dowsers indicated their ability to sense different kinds of substances (base metals, precious metals, coal, oil, magnets, etc.). This prompted the development of a second class of tests which we could offer the participants as an alternative or an addition.
we derived the following hypotheses to be tested:
(a) Dowsers can in at least 83% of all cases tell whether water is running inside a plastic pipe or not, whereas the expected chance success rate for this is 50%.
(b) Dowsers can in at least 80% of all cases tell in which of 10 boxes a previously agreed-on item is located, whereas the expected chance success rate for this is 10%.
The results demanded were below the abilities claimed by the dowsers. They themselves claimed a success rate of at least 90% or, usually, 100%. Based on the hypotheses, two outcomes were possible:
1. The dowsers would produce the required results. This would indicate the possible reality of the dowsing effect.
2. The dowsers would not produce the required results. If the results of the group of dowsers were distributed as would be expected according to chance, that would confirm the chance hypothesis. But if the distribution were to differ significantly from the chance expectation, this could serve as a starting point for new experiments using new hypotheses.
During the whole project, particular attention was paid to informing and involving the participants. The test could be meaningful and significant only if the participants shared our opinion that the test could lead to a definitive statement about their claimed abilities. To ensure equal treatment of all participants, we distributed all information in writing and formalized the further treatment before and after the actual tests according to the following pattern: After the official greeting by the GWUP and James Randi, each participant was supplied with extensive written information on the design of the test. Contained in it was a questionnaire we had developed. In it, all participants confirmed that at least one of the aforementioned test formats was suitable for testing their abilities. All participants also declared that they had been given sufficient information about the tests both in writing and verbally.
Declarations by the Dowsers Before and After the Tests
I DECLARE THAT I HAVE BEEN GIVEN SUFFICIENT INFORMATION ABOUT THE TESTS BY THE GWUP AND BY JAMES RANDI BOTH VERBALLY AND IN WRITING. IN PRE-TRIAL RUNS, I HAD THE OPPORTUNITY TO ADJUST MYSELF TO THE CONDITIONS, AND I FEEL PHYSICALLY AND PSYCHICALLY ABLE TO SUCCEED IN THE TEST UNDER THE GIVEN CIRCUMSTANCES.
I DECLARE THAT THE TESTS WERE CONDUCTED IMPECCABLY. THE TEST CONDITIONS AND THE SCHEDULE HAVE IN NO WAY IMPEDED ME DURING THE TESTS.
Someone can always claim that we tested the wrong dowsers, used the wrong hypotheses, or expected too strong an effect.
The Hessische Rundfunk TV network, who paid for the expenses of setting up the dowsing tests, had covered the proceedings assiduously. Their crews were unobtrusively everywhere, taping every aspect of the tests. Such involvement of personnel and equipment, aside from the outlay of expenses for the basic water delivery system and security procedures, is quite expensive. They had planned to prepare a TV special, and GWUP had granted them this right in return for their participation. Crews and executives from the network were as eager as all of us to see the final results, but as it became evident that the dowsers had failed spectacularly, interest faded quickly. Crews packed away their equipment, scheduled post-results interviews were canceled, and the TV special never took place. It was a case of a "non-story" to Hessische Rundfunk, though if the dowsers had been successful, we expect it would have been a celebration of rare dimensions.
The thing is, any or all of the dowsers could have objected to the plastic pipe and said that was not a fair test of their abilities, yet they all agreed that the experiment as designed was a fair test of their abilities, so none of them had any objection to the plastic pipe.

I do know that running water in metal pipes, both copper or Iron can be detected by the people I know. I would not think a plastic pipe could be detected, it is an insulator and absorbs signal.
