If you are looking for that Christmas present which is a little different, then Amazon has this UFO detector.
More than 1/3 of Americans believe in UFO's and one in 10 Americans believe that they have seen a UFO according to a study by National Geographic Channel. UFO sightings are reported all over the planet by thousands of people. The real question is whether UFO's are interstellar vehicles visiting Earth? Most UFO sightings can be classified as misidentified aircraft, planets or other aerial phenomena, but not all of them. There is a small percentage of UFO sightings that can't be explained by any known aircraft or natural phenomena. It is this small percentage of UFO sightings that create an exciting possibility. Over the years real UFO sightings have reported simultaneous electromagnetic disturbances. The UFO Detector is designed to sense these electromagnetic disturbances and signal their detection flashing 16 LED's simultaneously and beeping. The elegantly designed transparent plastic case is a handsome sculptured conversation piece that's allows one to see the electronics inside the case. Suitable for display on a desk, shelf or bedroom dresser. Size is approximately 3" dia. by 4.25" tall. Uses a 6V wall transformer
The reviews are a little mixed.
