Those of you that are familiar with the pet rock craze of the 1970′s will probably need glasses to read this article.
At the time an advertising executive named Gary Dahl bought ordinary gray stones at a builders’ supply store and marketed them as real pets, complete with a manual on how to teach the pet rock to do some tricks – apparently “sit” was quite easy, “roll over” required some assistance from the trainer, and potty-training was quite a challenge.

The researchers already knew that unlike other materials, rock crystal has an amazing ability to hold electrical energy, potentially a form of information, under control and send out electrical impulses or vibrating waves of information.
