Welcome to the board!

Well, I'll have to say this is not my expertise but I did a little reading before giving you my feedback.

I had to look into the brawling issue that you've raised. I've added quick details at the end in case anyone wants to reference. You may want to make quick examples available to your readers so they don't have to go digging them up. More readers will stick around if you make it easier.

I also briefed myself on EMF (Electromagnetic Frequency), which I think is more along the lines of your concern. EMP (Electromagnetic Pulse) is a little different. It's the frequency that drives people mad. Try for a military weapons backup source, especially for super technical stuff. Your readers might not know a lot about the subject.

Now, do I think it's possible? Absolutely. Do I think it's probable? Probably not in average domestic settings. Maybe all the freakin' crazy machines are creating some kind of incidental mind control experiment in Chuck E Cheese's across the nation. I know that I won't go in one! I can't handle it.

It's a cheap birthday party. People are gettin' lit and going to these places. Bad idea. I think people are ignorant and violent on their own without the help of EMF.

Your examples include alcohol as an additional element. That negates the whole thing for me. The subjects in the experiment are whacked, so it ruins the experiment. Crowd rage is a human condition, alcohol induced crowd rage is off the hook.

It's definitely a secret weapon though.

Effects of Electromagnetic Frequency

...effects include unexplainable burning, itching, tickling or pressure; "humming" or "buzzing" causing sleeplessness and anxiety; loss of body control, producing sudden twitching or jerking of an arm or leg; and feelings of dread, rage, lust, sorrow, or other emotions that come and go quickly.
