I saw another video like this, only it wasn't a beaker.

In the video, the folks at Earth Unplugged meet up with BBC's Steve Mould to explore the secret to these self-siphoning beads

It's a siphon.  Mystery solved.

Why does io9 call them "magnetic" beads. They aren't magnetic.

Direct link to the video, for those who also hate io9. I'm not sure how I feel about the softcore porn music they use for the soundtrack in this video, but it does indeed look cool. :)

Because io9 is a bunch of idiots that rarely understand the contents of their stories.

At my house, they'd fall for about 4 seconds, then hit the first of 4 thousand knots that would form in the chain.

io9 seem/s to have gotten tired of commenters pointing out that the beads aren't magnetic, and have/has edited their article.  Wusses.

Any rope or chain will do that over a sharp edge, once enough has gone overboard to pick up some speed.

It's just getting flung outside as it goes around the tight corner.

I haven't gotten to the end of the video yet, but I'm wondering how they filled the beaker without any knots forming. Doesn't even need to be a knot -- I would think it would form kinks and get snagged, etc.

Yeah, so did I.  One of these days, I'll run new wire to the breakers and I'll use that chain method to do it, too!

The height of the beaker also affects the length of the hanging chain and thus the amount of weight and the speed at which the chain moves. Makes sense to me, right?

There used to be this stripper called "Mitzi" that did something like this.

That and fire ping-pong balls into your beer from across the room.

Ok now we need two buckets filed with half inch link chain and a very very very tall ladder with two volunteers that have good medical insurance.  Toss the chain out of the first bucket from the top of the ladder into the bottom bucket, once it gets going good, run the buckets up the other direction of the ladder.  See how long we can keep this going.

I'm not sure it's working this way, but if the bead is gaining speed from falling, then falling from higher up will result in faster velocities. The difference between falling 1m and 2m is about 2m/s. Instead of ceasing acceleration at 4.3m/s, it stops at 6.3 m/s (rounding to the nearest tenth).

The problem with science is most of us watched for about 5 seconds before someone asked, "isn't this basically a slinky in a beaker?" and then went back to working on our seminar talks.

The same way one would stuff a rope bag without knots.

You don't grab a big bunch and shove it in, you feed it foot by foot (Thats what she said!).  Don't twist, wrap, roll, the rope, just feed it in 6 inches or so at a time.  The string/rope will naturally lay flat and then feed out flat when you pull on the end.

It's also not about time to change directions, it's called angle occlusion, and if they had ever taken even a rudimentary molecular mechanics class they would know this. You'd think a physics dude would know that, but nope, dude's a tard.

PekiAs a consequence of all the things duke here just described, the distance from the ground to the beaker effects how far above the lip of the beaker the beads fly, So the height does matter.

I would have loved to see this start on it's own as opposed to a strong initial toss getting the whole this going I'd like to see them take the end piece, dangle it over the edge and slowly pull it down (over the edge) until physics takes over. I'm also curious if that initial yank is essentially a catalyst  inputting enough energy into the system for gravity to take over in such a spectacular an wacky way.
 
2013-06-28 03:15:59 AM
Not sure where he came up with the chain hitting the side of the beaker to create the waves. Looks more like tension waves due to the coiling and uncoiling of the chain stock made from hollow balls and wire guage segments.

Or the same physics that allows you to siphon liquid out of a container if the other end of the tube is lower than the starting point once you "prime" it.

Ugh, they need to learn to extrapolate further. Why do "So if I hold it up here..." when they could do "So if we place it at the edge of this rooftop..."
 
2013-06-28 08:52:41 AM
Somehow I'm the only one who mentions that that type of chain doesn't bend as easily when it's taut.  That's how you get such a large arc -- the beads are pulled taut as they're yanked out of the beaker and that's as fast as they can turn around when they're like taut.

The guy in the video says it makes sense because the beads at rest are being pulled up, but they aren't -- they're being pulled sideways.  Or at least they would be if not for the fact that the beads can't form that steep of an angle when taut.

You will not get the same effect with rope or string or anything else, because those objects can bend at a much steeper angle.

ta-da

Why did they not take the next logical step and go to the top of a building and do this over the side?
