An informal study was conducted at the Tucson Gem and Mineral Show in February, 2006.  People were asked to put their hand over the Perkl-Light as shown in this picture.  They were then asked, "Tell me if you feel something," and "What do you feel?"

121 people were tested, of which 33 identified themselves as energy practitioners. The results were as follows:

	Number Tested	Felt Something	% Feeling
Practitioners	33	33	100%
Lay People	88	73	83%

A variety of sensations were reported, which varied substantially from one individual to the next.  We won't tell you here what people felt, because we want you to have your own experience!
