I live about 100 miles north of Groom Lake. They test all kinds of things like microwave weapons to knock out communications. Once or twice a month my cell phone squelches worse than any CB you've ever heard. This lasts for a few hours.
I've also seen unmanned vehicles flying in the area, some going almost faster than the eye can track them.
Usually, it's a matter of acids and bases, so there is a certain "science" about it.
For example, making cheesecake, I add some lemon juice, which gives it a nice tang to offset all of the sugar I've used.
