Thats pretty cool... but what I want to know is what you were searching for? "World's longest *"??
Not only is the article years old, the whole concept is corrupt. No Slinky worth it's salt is slung by wires.
Now all I need is a way to get that slinky through customs and past the metal detectors.

What I love is how every time the author of that page makes a reference to his "sliiiiiinky", he changes the number of "i"'s in the word ;)
for me, We're doing wave theory in physics at the moment, it's fun wasting hours playing with slinkys in the name of physics :-)
/* FUCK - The F-word is here so that you can grep for it */
someone made a really long slinky.
Today I have a really long face. I don't see that in slashdot.
I went over ALL the pictures and by FAR this is the best one

props to all the horny gals in california who like to masturbate in my car.
Color flashing, thunder crashing, dynamite machines.
"34 slinkies soldered together." Can't be that tough, surely? It's made difficult by all the supports this guy has come up with in order to elevate the slinky. If you wanted it to make pretty patterns (not lie on the floor lifeless), you could probably just wrap it around a large metal tube. Then you might get some interesting noises as the slinky vibrated around it.
:)
I did run a check on the Guinness Records site to see if there was any record for the longest slinky, but apparentely not. Anyone want a quick and easy record to break?
I bet it would look quite funny in zero gravity (without the suspension stuff).

michael, go to bed man.
No arguments here, but what have they done to her feet!?
So this is the truth about trolls!
...how well does it walk down stairs?

It shoots so high in the sky.

Everyone knows its Slinky.
The best present yet to give or get
The kids will all want to try.

Everyone knows it's Slinky.

Interesting story about the inventor of the Slinky, his instant success, his wealth, his joining a religious cult...

I don't mean to sound picky, but surely a slinky is more than a helix? If it doesn't walk down the stairs, it's not a slinky to my mind.
And this thing - impressive though it is - doesn't look like it's going anywhere.
The World's Longest Slinky will be useless without the Worlds Largest Starcase.
"1: characterized by slinking : stealthily quiet <slinky movements>
2: sleek and sinuous in movement or outline; especially: following the lines of the figure in a gracefully flowing manner <a slinky evening gown>"
So, if it moves sinuously or wears an evening gown, there's no doubt.
A friend made me promise to contact the Guinness Book of Records about Sliiiiiiiiiiinky. I haven't done so yet. James Industries - who have manufactured the Slinky since 1945 - say they don't know of anything like it.
.wav on the site soon. In the future, there will be some video too.
That's the algorithm - just hold the 'i' key down for as long as you like!
The suspension is elastic - not wires. This is my attempt to firstly free the Sliiiiiiiiiinky from the constraints of gravity and secondly unite a small number of Slinkies, or rather create some subset of the one true Sliiiiiinky, since the factory insists on chopping Sliiiiiiiiiiiiiiiiiiiiiiiiiiiinky into such short fragments.
Yes, they should do this in the new Space Station - it would be a lot easier than all those elastics!
I don't have any audio samples on the site, but now that techie slashdotters are perusing it, perhaps I should. Sending an impulse at one end - by tapping with a coin - generates a short pulse of all frequencies. The high frequencies travel faster than the lows, due to some effect of the stiffness of the steel. (This is apparent at the 0.5 to 5 Hz range of the big visible waves too.) At the other end, a piezo pickup gets a "chirped" sound, a high tone rapidly descending to a very low tone. It sounds just like a swept oscillator. Since I figure no-one else has 645 metres of wire = 2,116 feet suspended in a way which supports vibrations of frequencies almost from DC to daylight, I figure I could get another gong in the Book of Records for the world's most serious *chirp*. Let me look around and see if I can put a
Stairs are boring by comparison - Sliiiiiiiinky enables anyone at all to make transient three dimensional kinetic public art - and there's no electronics involved.
Sliiiiiiiiiiiiiiiinky may be having another outing at Beckett Park in late March or early April - write to me if you want to come.
As for the favorite photo of the Space Cadets, this is part of a page http://www.firstpr.com.au/slinky/tourism/ Well gents, isn't true that so much of our efforts go, ultimately, to keeping fabulous women smiling and gyrating? Ms Yellow Cadet worked at a computer shop and now is one of the organisers of Melbourne's best trance techno outdoor parties. Ms Blue Cadet worked on a very high floor of some god-awful city building, for a *bank* of all things. I hope she has transformed since then. . . . . . . and fellas, when it comes to this particular approach to getting girls gyrating, mine's longer than . . .

Is the record measured at it's max length?
It looks like that thing could be stretched at least twice that long. I mean if you're going for the record, go for the record!
Alright, theres a problem with welding loads of slinkys together and setting them off down stairs:
:)
When your slinky has finished unspooling off the top step, its rear coils then swing over the top of the slinky to fall on the next step, this after a point will preclude an indoor venue due to the height clearance required. The Pyramids may be the only option.
As slinkys get longer, they also fall over more than one step at a time (I know they shouldn't but its something to do with rigidity) - Is this cheating?
And finally, very big slinkys with small diameters (across the coils) become unstable (I know; I'm a muppet, but I just tried this:) and fall flat after the first step and slide to the bottom. So your longer slinky needs a wider 'foot'.
All in all, it make the challenge of creating the woulds largest working slinky look quite something
Ripping an new rectum in the fabric of spacetime.
I have aways wondered about putting a slinky on an escalator. With proper tunning i think a perpetual slinky could be made to work. The trouble is i dnt have a slinky at the moment my last one broke :( they are now made of plastic so you cant end them back to normal.
Has any ine tried a slinky on an escalator? does it work?
well just an idea
Sorry mods for this being grossly off-topic, but I was waiting for any story with a mention of Google to post this :)
Go to Google.com, type in "FreeBSD" and what's the number 1 result? www.gnu.org! What's all the more alarming is that the word "FreeBSD" doesn't appear on the page in either visible text or HTML at all.
May be a nitpicking point, but I've seen IRC bots and web scripts that just pick Google's #1 search, so this is weird. Sinister global conspiracy? We all know that Google is running several thousand GNU/Linux boxes...

I'm positive it doesn't fit in the latter category... it's a bit of a stretch (no pun intended) to fit it in the first.

Someone should put this guy in touch with NASA, since it seems he has come closer to building a space elevator than they have.
Saw that this summer. At Wallops Island Museum (NASA) I saw
a move made on various shuttle flights with astronauts
playing with various toys in 0 g. They spun tops, bounced balls
and did a slinky. I don't know if you could find
the film on a NASA site but try.

who glanced at that at 7AM with weary eyes and thought...
World's Longest Stinky
and thought oh dear.....
I'm suprised no one has mentioned this yet. Check out the last set of pictures on the bottom of the page, some interesting stuff going on between those two girls. Would you classify that under Slinky porn? If I build my own "World's Longest Slinky" is that the kind of people I should expect to attract with it?

Earthcore NYE 2000 was a weeklong techno-marathon ... the sliiiiiiinky was there on a hill very similar to the one in the "space cadets" photos. It moved so gracefully on the elastic strings it's suspended by. A slight movement on one end creates a lovely fluid ripple along the length of the whole object. People creating ripples on both ends make waves that gently join each other. Very peaceful to look at.
Both Earthcore and the Sliiiiiiinky are not to be missed if one's in the Melbourne area!

In Denmark, there's a place called 'Experimentarium' where you can experience physics phenomenae first-hand. :)=
One of the regular exhibits is a slinky like the one mentioned in the article (there's a picture here).
Okay, maybe it's only 15 metres long, but OTOH it's been around for several years, so there.
I'm on Slashdot!
Hmmmm.. Do I detect a Shrek reference here?
I haven't tried it, but I suspect there are some fairly hairy stability issues here. An escalator, at the slinky scale, does not move all that smoothly. There are vibrations, stop-and-go jerks - I'm sure you could make it work for a few minutes, but any more than that is unlikely. Please not, I am not a physicist, slinky expert, or even a particularly good student or smart human being.

Why is the girl in this picture wearing a helmet?
I think I'll stick to regular sized slinkies so I don't have to remember to wear a helmet. The number of slinky related deaths each year is growing. Please remember that playing safe is playing smart.
Its nice to see Robin Whittle getting some well deserved recognition on slasdot, but may I remind you all that this is a late post, as its over 3 years after the event, and the outdoor dance party event, where his work has gained exposure, and is promoted on his site, has changed considerably since then, in spirit, and ownership, and integrity, which has to be acknowledged and considered with clinical awareness, and consideration, before putting too much sentimental praise, on this past event. Such is the journey of time ...
We are in a new millennium, with new consciousness and direction, may the resonation slinky direct us to the new path.
Please be reminded that the outdoor dance party event mentioned, is not what it was then, is run by a different company, with a different outlook.
However, may the resonating frequencies of the slinky take us forward to the new pure hearts.
Thank you Robin for your genius and inventing imput into this cosmic realm.
May all new parties to the slinky enjoy its inspiration.
There's a link in the linked article to a 15-meter slinky in Denmark, but it's broken. The current link is here for the English version.

If you look closely at some of the pictures, you can see that they are fake. It just doesn't look right. Does anybody else think so?
Perhaps were a long slinky made to be double funnel shaped? It would have a wider foot yet would comprimise on the stability issue. I imagine it would also be top-heavy past the midpoint and thus require less energy to make the transition to the next step...
So how does this thing do on a set of steps?
Fortune has a quote along those lines.

look at that link... I would love to see that..
For the cruising hordes of slashdotters, I scrambled some audio files and frequency analyis and have added these to the site. This includes analysis of a chirped impulse response which spreads the frequencies out in time over more than 2.5 seconds.
Christian mentioned the DJ booth at that Earthcore party. Cat (my Devil Fish assistant at the time and Sliiiiinky co-pilot) and I were at an excellent smaller party at Nagambie on NYE, and we arrived at Earthcore on 2 January. People were raving about the big night! The main floor was on the top of a hill, with the DJ booth being the front part of an old Victorian Railways diesel loco. It is all made of 1/4" steel.
Some of the crew saw it on a truck going omewhere, and they spoke to its owner and hired it for a few weeks. Behind it is the very dry reservoir of Lake Eildon. Cat and I surveyed the scene. Two crashed light aircraft and a motor car tumbling on a horizontal axis were parts of the decor. A bulldozer doubled as a lighting stand . . . there were other huge sculptures. The thing on top of the loco cab is a ferocious tesla coil of a chap also called Robin. Apparently there were wires all over with sparks leaping around the place and people all said that that night, everthing just went **off**! The local fire brigade was on hand, since the place was as dry as buggery and was a real fire hazard.

Csound, 21 metre Sliiiiinky, the Gentlemanly Art of
Nothing like seeing the world's longest stinky, and I sure didn't want to see low frequency waves traveling down it.
First off here's a simplification that anyone can try. In my high school physics class (many years ago ;-) when we were studying waves, one of our lab experiments was to go out into the tiled-floor hallway. With the help of a lab partner, we'd stretch out a slinky along the floor. We experimented with creating standing waves of different periods. This permitted experiments in the horizontal and longitudinal axes (though not in the vertical, which the sliiiiiinky also supports). So, try it at home!
Secondly, I have a suggestion concerning the tendency of the sliiiiiiiiiiinky to get tangled onto itself that was often mentioned in the article. Wouldn't an initial tensioning of the sliiiiiiinky reduce or event prevent that from happening? I'm thinking the use of some cords, strings, or bungie cords being attached to the ends of the sliiiinky and whose other ends would be attached to the endmost vertical support poles. The downside, I would expect, is that the wave would move more quickly down the length of the sliiiiinky.
What, no bullshit post about Alan Thicke dying yet, whoever does that is dropping the ball.
Hmm, I wonder which ham bands it'd resonate on.
Is it fun for both boys and girls?
still, it was an interesting idea
A close friend had two sewing needles, closer to toothpicks than the spears that knitting needles are, impounded. They also took the twezers, like someone could have there eyebrowes picked to death or something. But I suppose, it depends on several factors, what security droid on what day at what airport decides exacly where the line is drawn.
