you could change the word magic to 'ordained by God' - still magic as far as science is concerned though.
Okay, I understand that philosophy. Then by that thinking, a crystal is just as magic as a "lump of rock" because both critically depend on the "God-ordained" electromagnetic force for their physical form and properties, including the piezoelectric effect.
What I am extremely skeptical of is the idea that someone with a wikipedia-level knowledge of the piezoelectric effect has discovered significant new uses that scientists have overlooked. Scientists all over the world are researching all the time trying to find new uses for this effect, with the motive of profit. They understand all the complex mathematics and physics behind it, and so far have made all kinds of real, working things with it from microphones to cigarette lighters to magnetometers that detect submarines from an airplane. I think your chances of winning the lottery are better than you stumbling upon an undiscovered use for the piezoelectric effect.
You may see the piezoelectric effect causing some weird things to happen, like how static electricity makes a balloon stick to your head, or how magnets attract and repel each other. But this doesn't mean you've discovered something magical that science doesn't know about, or that you've discovered something that has any use other than for a science demo.
