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.

Storm Water Gun, by Jakks Pacific http://www.sscentra...views/storm600.html
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.

possibilities for a VLAN. [+]

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...

Which will hopefully be a good distance, because

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.
