Let me guess, the video has some commercial music in the background? Youtube just shows me “This video is not available in your country.” when accessing it from Germany.

Whoever recorded that video is terribad at filming. I just want one steady, stable shot of the whole thing. I don’t particularly care for shaky half-frame closeups of some old beardy guy or you playing with the water. Add on the music licensing and this video is completely useless.

This video is not available in your country. This is getting really annoying….

ripped the video and re-uploaded it for those who could not watch it. http://www.megavideo.com/?v=XA5EAB4R

Disney world if I recall correctly sends theirs through a collum of fine mesh screens

pesky music mafIAA..
why won’t they just go away, their business model is outdated and obsolete.

neat video FWIW

I’ve wanted to build one of these for years but I just can’t get around to it it seems. I do wonder if there aren’t easier ways to “inject” light than to put an optic fiber in there though.

Really incredible. Having not previously been aware of laminar flow jets, I spent half the video wondering why they were making such a big deal about this tank with a clear plastic hose coming out of the top…

Surprisingly easy to build too. Shame I can’t think of any use for it right now.

@Osgeld. You are right. I worked for a hire company that specialised in water effects and these jets where one of the things I would have to maintain regularly, keeping the screens as clean as possible to keep the jet perfect. The ones we used had a blade attached to a large stepper motor to cleanly chop the water stream for great jumping jet effects. I was working on a way to miniaturise the jets before I left the company.

It’s interesting to hear about this, I followed some links and got this video with traveling light in the beam and I assume that’s done by pulsing the light with just the right timing? And that would be a nice project for an – dare I say it… arduino?

@willyshop

Yeah, no L in straw, but there is a ‘ue’ in ‘due’.

And he mentioned surface tension, was just using magnetism as a comparison, not a scientific term.

I’ve been working on this for over a year now, and am getting some where! I started my project blog and have some information on it there, as well as a forum. They are really simple in principle, but can be a bit difficult to fine tune. I’ve been able to get mine to shoot about a 14 ft arc about about 3 ft high. They are almost completely silent, and stunningly beautiful!

Is such a stream more effective when let’s say cleaning your hands? And is it quiter when filling up a bathtub? It certainly looks nicer.

Great project!

See, when I see things like this, I immediately think of the Anti-Gravity mechanism that requires rotation of a magnetic fluid. If jets like this could pump streams of magnetic ferro fluid into a coil under vacuum, it should reach the superconductivity necessary to manipulate the gravity field….

But, maybe it wont work with anything non-water based… Any ideas?

since my last comment is awaiting moderation, have part 1..

Just wanted to comment on the travelling light through the water.

This has nothing to do with pulsing light at the exact right timing. Very nice effect though.

There is no way you could make light pulses travel inside a water beam or any other medium for that matter like this. This would mean that the photons start behave like matter – like the laser guns of Star Wars and Star Trek etc. You can’t do that.

Water will have to flow, and light will have to be on all the time during the time the light travels through the beam.

The only way to make this happen is to inject some kind of particles in the beam of water that disrupts the perfect water beam making the light escape from the edges of the beam. OR you can disrupt the beam in some other way like vibrating the nozzle or something with a small hammer like mentioned. Either way you will create interference in the beam so that the light escapes. If the beam is not disrupted, it works as a fibre optic cable, or close to it, containing most of the light all the way.

Make the beam vibrate, viola, you have a pulse of light. But the beam is lit up all the way, you just dont see it unless you disrupts the laminar flow…

I think people have tried for ages to make light behave like matter, but I don’t think any have done it yet, and you most certainly can not do it if it’s possible at all, with a home made 200 bucks water fountain :). Unless you live at CERN :P

The technology is already patented, originally being used to channel laser light to cut silicon wafers, whilst cooling at the same time.
The advantage being no jagged edge damage to the chip,
