This sounds very hokey (in a metaphysical way), and I am sorry for that. It isn't, it is a very serious question.... A number of years ago a friend gave me a "healing wand." It is nothing more than hard copper (water) pipe(maybe a foot long?), and a natural quartz crystal "point". But this thing creates heat? When it was given to me, the friend made me close my eyes and hold my hand out so I couldn't see what she was doing. She swirled this thing over the palm of my hand slowly, about two inches above my hand. I could actually feel this hot spot going around, and I could also feel it "drag", like the spoon indentation when you stir pudding (does that even make sense?). I have done this same trick to several complete non believers, and they were stunned at the amount of heat you can feel. How a short piece of copper pipe and quartz can create heat is beyond me. I have since played with many of my points in my rock collection, and have found that some naturally give off a tiny amount of heat, while others seem not to. And in the metaphysical world, the copper magnifies this "natural energy." I have hesitated asking this question here for the longest time because I fear being put in the box of a looney believing metaphysical crap, so please just scientific answers only? Even if it is a guesstimate of how this heat is even possible from just quartz and copper?
