How to make Rochelle salt piezoelectric crystals

Step-by-step video on how to make Rochelle salt crystals or piezoelectric crystals for doing piezoelectricity experiments or hacks for science fairs or fun. Includes details on the ingredients: baking soda (sodium bicarbonate), cream of tartar (potassium bitartrate) and distilled water.
