Piezoelectric materials are about as close to magic as you can get. They turn physical pressure into electricity and can even turn electricity into physical pressure – an amazing sort of bidirectional converter for mechanical and electrical energies. Perhaps even more amazing is the fact that you can easily ‘grow’ your own piezoelectric crystals overnight using just a couple of common ingredients – awesome.

Ever since I made my first contact microphone, I’ve been amazed by piezos and their unique abilities. I was more than psyched to learn I could make my own piezoelectric crystals after finding recipes online. Now I just need to figure out how I’ll put these little guys to good use … feel free to leave any ideas/suggestions in the comments below!
