Rod-shaped objects moving quickly through the air were claimed by some to be alien life forms or ghosts, but subsequent experiments showed that these rods appear in film because of an optical illusion.

Aka :Streaming ghost, swimmers, energy rod, light

: Rods were discovered in 1994 with the advent of high speed video cameras. They appear on video stills as long objects with undulating fins along the side.

Rods have been captured on video tape by many people as they fly through the air indoors, outdoors and underwater. Jose Escamilla was the first person to make rods known to the world and Daniel Bethel claims to have captured and released one these creatures.

Theory: Skeptics pretend that rods are elongated artifacts produced by cameras that inadvertently capture several of a flying insect’s wingbeats. Investigators have shown that rods are mere tricks of light which result from how images (primarily video images) of flying insects are recorded and played back.

In particular, the fast passage before the camera of an insect flapping its wings has been shown to produce rodlike effects, due to motion blur, if the camera is shooting with relatively long exposure times.
