How Do They Do That? A young man of Dublin walks past a row of streetlights at night--and they go out, one by one, as he passes. An engineer in Woodville, Washington, is stopped by police and his car searched to find out what he's doing to their streetlights. An Australian in the entertainment industry parks his car in a parking lot, and the light above him goes out-until the following evening when he parks in precisely the same space and the light comes on again. And that's not all. When a guest in a restaurant in Athens, Greece, asks that the music be turned down, they refuse--whereupon she "kills" the restaurant's electricity and they eat the rest of their meal by candlelight. Other people affect traffic lights, computers, railway crossings. This is Street Light Interference (SLI). Once considered to be folklore--something that happened to a friend of a friend--today it is recognized as a scientific enigma with implications for our knowledge of the universe, including ourselves.

In this, the first full-length book on SLI, we hear from some of the hundreds of SLIders who have reported their uncanny experiences, and consider the wider implications of this fascinating phenomenon.
