To conduct the experiment, infrasound and electromagnetic wave producing speakers were hidden inside the "haunted" room, to simulate the frequencies associated with paranormal experiences. Volunteers were then sent inside and asked to report any "strange feelings" as soon as they felt them. If there was something to the business of paranormal experiences being genuine, then there would be a correlation between the speaker zones and the sensations reported.

As you can guess by now, all the sensations of dizziness, tingling, disembodiment, dream-remembrance, and arousal had no correlation to the volunteers locations within the room. Researchers concluded that the responses were due to suggestibility and the fact that the volunteers were expecting to feel something.

They did leave some room for skepticism and said that it is possible that some individuals may sense things that others can't see, but frankly I don't care either way. I'm still going to keep on believing in fairies. [Wired]

Nikola Tesla's Spirit Radio is built with a simple crystal radio circuit, but it has the ability to generate spooky sounds from all kinds of electromagnetic interference. Some, like Tesla himself, believed that it had the power to pick up on supernatural forces. It actually creeped him out:

"My first observations positively terrified me as there was present in them something mysterious, not to say supernatural, and I was alone in my laboratory at night."
- Nikola Tesla 1901

Cameras with infrared night vision are often used in ghost hunting to detect hot spots in darkened rooms. The Vivitar DVR 150 includes this capability in a convenient pocket-sized form. [Vivitar via Link]
In addition to looking for hot spots, ghost hunters almost always employ some sort of EMF meter to detect sharp fluctuations in the surrounding magnetic field—supposedly a sign of a ghostly presence. Oh hey, Amazon is selling a two pack Gauss Master and K-II Deluxe EMF meter set for $85! How convenient. [Amazon]
If you can't capture a real ghost on film, you can always turn to the Ghost Finder disposable camera. It inserts an ghostly image in every photo you take—saving you time and effort with Photoshop. It's all of the fraud without all of the work. [FindGift]

Dowsing or "divining" rods have been used for thousands of years as part of religious ceremony or to ascertain the location of water or precious metals. Some modern investigators still believe that these simple rods can be used to detect the presence of ghosts. [Divining Mind]
Trisaksri was a short-lived ghost repellent concept that would detect ghosts in the home with a low level magnetic field and a camera. Once discovered, the unit would emit a "Wave Killer" Radio wave blast to eliminate any unwanted, otherworldly intruders. [Link]

If the answer is "yes," then don't wait another minute. The folks at Supa Boondee shop are ready to believe you. Their solution: the Trisaksri Ghost repellent. Simply switching the device to the "On" position will detect ghosts with a low level magnetic field and a camera. This "invisible picture" completes a circuit that results in a "Wave Killer" Radio wave blast that should send ghosts and devils back to hell.

Currently, Supa Boondee is debating whether or not to go ahead with a full-scale launch of the product—but at the very least, a prototype will hit eBay in a couple of weeks. So, keep that in mind if the exorcist doesn't work out. [Supa Boondee via Boing Boing Gadgets]

The weirdest part of all of this is that 20 years ago, when Frank and his family moved into their house in the British resort town of Blackpool, they were plagued by paranormal behavior. Doors were slammed, bedclothes pulled off the kids while they slept, taps were turned on—and all this was put down to a malevolent presence called "The Thing."

So, the Joneses called in Blackpool's answer to Ghostbusters, the Fleetwood Spiritualist Church, who cleansed the property of The Thing, according to them a spirit "trapped between two worlds." For five years everything was A-OK until the family was hit by a double tragedy: first the death of son Steven, then Sadie just three months later. After she was buried, the weirdness returned.

Shortly after his wife's death, Frank claims to have had a missed call on his mobile, which didn't ring. "The call was from my own home number, but there was nobody in the house," he explains. "When I went inside there was a smell like cigarettes which Sadie used to smoke and the smell of her perfume." The 59-year-old also claims that his late wife has been sending them all SMSes from beyond the grave. "There have been messages with words Sadie would say but there's no number." [The Register]

One guy might've had it right: Maybe it was a plastic bag. Could it have been an out-of-focus blue plastic bag dancing around with the wind like that one in the film American Beauty? Could an image artifact like this have been caused by a cheap security camera? In this video, it's unclear whether people saw this "ghost" with their own eyes, or just watched a video of it. Mysterious. Pranksters at work? [Liveleak, via Neatorama]

Although it looks great, the glass on glass design guarantees it will shatter the instant it gets too heavy for the piddly mounts you hang it with. Which is actually why they want this thing: they really hate their baby. – Jason Chen
