If you like pranking your friends and family, you better hold your horses because we may just have the best tool to pull pranks with.

The Ghost Detector - Radar Prank is a great way to trick your friends and family who get scared easily. It lets you pull some tricks by scanning the place and showing high make-believe frequencies and magnetic fields. The only thing you need to do is act as if there is a ghost around.

Note that this tool is for pranking only and does not actually detect ghosts and other paranormal stuff.
