The Circuits Parts There are two simple circuits for creating negative ions (there are more, but I'm only covering the easiest and most effective). The first circuit uses power from the mains, a voltage multiplier, and a metal antenna.

## High Voltage Happiness? How to Make a Negative Ion Generator « Fear Of Lightning

The circuit schematic is represented in the (incredibly detailed) drawing below: The generator charges you up like a capacitor, then when you come in contact with a grounded object (person), the voltage is discharged through them. I found it was best to put the generator, battery and switch inside an old shoe, like so (the "stripped" wire is ground): Of course, to get it inside the shoe it's necessary to do a little drilling...

## Can The Human Brain See Quantum Images?

The strange rules of the quantum world lead to many weird phenomena. One of these is the puzzling process of quantum imaging, which allows images to form in hitherto unimagined ways. Researchers begin by creating entangled pairs by sending a single laser beam into a non-linear crystal, which converts single photons into entangled pairs of lower frequency photons, a process known as parametric down conversion. A continuous beam generates a series of pairs of entangled photons.
