Waser pistol

Water Amplification from the Simulated Emission of Radiance.
  [vote for,

Played with at dusk or in a darkened room, (preferably one with a drain), these water pistols are designed to create a cohesive stream of water which acts as a fiber optic conduit for the light emitted from inside the weapon as the trigger is pulled.

Adding pre-colored water to the gun intensifies the color of the Waser beam's light.

This device might be suitable for retrofitting a water pistol. [Amos Kito, Apr 13 2008]

These have a "Photon Light Source", and coherent water stream. Reviewers say the light has a low range. [Amos Kito, Apr 13 2008]


       Yay! This would be good.

       This will only work until the stream breaks up. I suppose you could extend it by adding polyethylene oxide to the water.

       Another fine invention from Elmer Fudd Laboratories and FuddCo, no doubt.

       the better an optic fiber is at what it does, the less it is visible. The better it is visible as a 'ray', the worse is the transmission... the proposed device is self-defeating.

       well the post is just for a toy, not for actual transmission of data, but there is possibilities for a water-fountain LAN.

       ...a peer to peer network even...

       // This will only work until the stream breaks up. //   

       Which will hopefully be a good distance, because   

       // these water pistols are designed to create a cohesive stream of water //   

       probably by using a laminar flow nozzle.   

       // water-fountain LAN //   

       Also a water-fountain WLAN, because it was discovered a few years ago that you can use a fountain of water as a radio antenna.
