I bought this: http://www.amazon.com/gp/product/B005P0DOTY/ref=oh_o02_s00_i00_details If you taste something bitter, you are a supertaster. http://en.wikipedia.org/wiki/Supertaster If you taste nothing, you're not. I ripped out three pieces and placed them on my and my two sons'tongues. I and my 7-year old son tasted nothing. My 5-year old son, however, tasted bitter and gagged. Can't wait till the man gets home.
