Ghostbuster on a keychain?
A ghost detector.
Yup, a real ghost detector that lights up and beeps whenever the presence of a ghost is nearby AND doubles as a keychain for convenient portability. Now when you feel the hair on the back of your neck stand up, or the smell of Grandpa's musky aftershave suddenly waffs to your nose, you'll know if you are just a victim of an overactive imagination or if a spooky apparition is really visiting you.
Not only is this gizmo useful, it's also quite attractive. It comes attached to a nylon strap with some Japanese writing (which is cool) and a little ghost figure that reminds me of a miniature Stay Puff Marshmallow Man. Plus you can get the Mini-Ghostradar in a variety of colors. (Too bad it doesn't come with a proton pack).
So how does the Mini-Ghostradar work?
The VP of SolidAlliance, this little keychain's manufacturer, Yuichiro Saito says, "This detects invisible phenomena and so the system is confidential. This is not a game. This is a measuring device."
Confidential? Hmm... For $18, you might as well give it a try. But it would help to know how such a gizmo detects ghosts.
Many speculate the Mini-Ghostradar detects surrounding magnetic waves. So will this little keychain start going off when I walk by my refrigerator which is covered by little magnets holding up my son's artwork??? I'm beginning to think that maybe this gadget is about as useful as a Petrock or Chia Pet.
Perhaps I'm wrong, and this keychain really works. If so, it could change ghosthunting forever. Now anyone can get confirmation that a ghost is in fact nearby. No need for expensive electromagnetic detectors or ectoplasmic detection apparatus.
So what's next from the Mini-Ghostradar manufacturer?
Gaydar with built-in USB flashdrive.
