Voodoo doll prank by MagicofRahat. What the f? How did he do that? A comment from a youtube user may give you an answer: He holds a device that plays a high pitched noise. (search it in youtube ‘High pitch sound’). It is not an audible frequency of a camera, hence it does not pick up the sound. It is also really hard for humans to locate the direction of the sound. Good work rahat, you trolled us all.
