This screaming fork strikes me as yet another way for kids to torture their parents at the dinner table. The EaTheremin, developed by researchers at Japan's Ochanomizu University emits a high pitched sound when the food carried by the fork meets the mouth, forming a circuit. Foods have different resistences that create varying sounds. I could have my own meat and two veg orchestra but I think I'll stick with run-of -the mill utensils for now.

While this fork screams a long series of connected notes for her. In Texas, where mouthes are stuffed far more efficiently, the sounds would be stacato blips and bleeps; it would be more of like the song of a 90's Nokia phone ringing...
Nothing new to see (or in this case hear) ... move along
