O.K., so, with three, or more, cellphone antennae aimed precisely at the kernels the transmission signals from the sound input to the cellphones all hit the kernels at the same time with the same signal phase, thus it would seem that an additive effect (constructive) interference of the transmitted beams concentrate in just one tiny area...an intense standing wave of microwave energy results,.and pop goes the corn!.....one cellphone won't do it....gotta have concentration and standing wave....
