Has anbody on here done it? Heard its the reasons for many injuries.The water surface tension must be pretty crazy!

In reply to sarah the wonderful: I once had an idea for a commercial for Bonios getting my dog to jump if after a Bonio, 'A dog will do anything for a Bonio' my wife wouldn't let me do it to the dog.
I thought you just chucked a rock in first to break the surface tension.

Haha I remember watching that! I love the voice over of the woman at the end (cant remember her name.) "Do not try this unless you are an expert like Tim"

Can you be an expert at jumping into water in an uncontrolled manner from a height? If so I'm an expert too... yay!

The trick is to chuck a rock in first and break the surface tension. I can't open the video so not sure if the great Tim does this.

Did it years ago with some LPMC climber types. I recall my back ached and water went up my arse.

If you like this sort of thing, try the jump at Loup Scar but get the landing right as it is ringed by limestone pavement just under the water.

In reply to John Rushby: Tim doesn't but there is a ripple on the water from wind (not sure if this makes a difference).

Two mates did it at uni. One complained while swimming back across the lake of water trickling out of his arse (it was water). The other had mild shock. However, the latter went back to do it again!

They will both enjoy this link no doubt!

Make sure you've got good technique already, or it f**king hurts. And dont throw a flat bit of slate as they tend to sink slowly and you can land on them.
My mate got massive amounts of bruising on one arm and couldnt remember the 10min after (shock?) and I got inflammation of the cartilage in my chest and sprained my wrist.


Funny though.

The voice-over is Julia Bradbury.

Just make sure you jump from the right side of it - the other side isn't deep enough!

Mythbusters Proved that chucking anything in before you land does not make any difference to the impact force.
 mynyddresident 19 May 2010
A friend hurt his knee, the dive manager also took exception (to the jumping rather than my friends lead of Soap on a rope I presume) and the police arrived tyres screeching and lights a flashing. Be warned

Would`nt be a good idea to throw a boulder to break the surface thingy as it could hit a diver on his noggen thus banning climbing in the Vivian, no not a good idea at all !

what? Throwing in a rock doesn't change the chemistry of water?! I find that hard to believe.

I saw that episode and thought that their experiments were pretty crap. although I wouldn't trust the myth unless there was a bit more science behind it.

Well i know someone who did it throwing the rock, and was fine. He then ran round to the top again, and jumped without throwing the rock. Result - Broken ankle...

In reply to mynyddresident:

Yeah, should probably wait until the dive people arent in the pool or have closed shop for the day.

Who would chuck a bleedin rock then themselves in a pool full of divers?...
 EZ 20 May 2010
In reply to smallerrich:

The rock seems to be a good idea:

"Some pools are equipped with an ' bubbler ' system to soften the crash of a poor landing. Before the diver goes off the platform, the coach switches on the bubbler and a large amount of bubbles comes from the bottom of the pool. If the diver is going to crash, these bubbles greatly reduce the sting of a bad landing." from: http://en.allexperts.com/q/Springboard-Platform-Diving-3780/platform-flat-f...

The jump doesn't!

In reply to EZ: Throwing a rock in wont have the same effect as blowing loads of bubbles through the water.
 Walshy 20 May 2010
chuck a rock in by all means. But don't expect it then not to hurt.

Everyone I know who's done it went to hospital, apart from me, but I couldn't sit normally for a month...

I would advise against it. Imagine not being able to climb for weeks or months because of some stupid jump...it's a no brainer.

In reply to cosreba:
The last person I saw do it was left unconscious, floating face down after the impact. They were only saved from drowning by a very fast swimmer. I've heard of quite a few other people getting injured, so i don't think it's worth it (plus, have you stood at the top of that thing! It's fooookin miles)

That's right - the swimming club here are very clear about the high board. You want 3 things:
1. to be able to see the surface, not the bottom (so ripples good)
2. to be able to tell which way is up (so no blue or light-colour tiles)
3. to have a bubble blower which makes the water actually a mixture of air and water. The air compresses on impact; water is incompressible (and the surface tension has nothing to do with this).

In reply to Walshy:
We hurt ourselves but not bad enough to go to hospital, and the other two lads I know who did it were fine to the point where they started believing all the tales of injury were a load of crap. Spose you just need to get it right.
 mynyddresident 20 May 2010

There was nobody diving at the time don't worry.

I think he's more worried about a serious injury occurring and jeopardising his business. Which is understandable.

If you get on that wall whilst the centre is open your in for some colourful language ,the same friend well tell you! Rope cutting threats..etc

oh, well there the irrefutable evidence that throwing a rock in before really works!

maybe, just maybe he didn't land the same way as the first??

yea maybe a myth, but its worth doing just encase

In reply to adam06: Nae point throwing in the stone first, it's the deceleration that causes the damage. Impulse = Force x Time. It's all physics folks!

 Michael Gordon 20 May 2010
In reply to el diablo:

yes but if you break the surface tension won't you slow the deceleration?
 Guy 20 May 2010
In reply to cosreba: Haven't done Nicky's but have jumped off the top of Durdle Door which is 90+ft and the key is getting a straight entry and keeping body tension. I had a slightly seated position on entry and it slapped my ar$e a bit but crucially I kept my back straight.

One of the lasses who posted on here a while a go jumped off Connor Cove and broke her back so it is risky. Personally having done it once it certainly isn't worth risking it again.

If you are really worried about surface tension perhaps you should drop a bar of soap in first. More effective than a rock. Insects might notice it, but I can't imagine it would measurably affect your deceleration. That's largely down to the incompressabiliy of the water, which is why aerating the water (bubbles) might actually help. The trouble is, too many bubbles and you won't float to the surface...
 EZ 20 May 2010
In reply to Michael Gordon:

Surface tension is a misnomer. The surface tension is the same whether there is 5mm or 5m of water, but yes, air bubbles will result in a deeper submersion.

Out of interest, how deep is the quarry?
 McGuinness 20 May 2010
In reply to EZ: 6-18m
 EZ 20 May 2010
In reply to hellome:

You'd not want to be going in like like a missile at 6m! You'd definitely want breaking as soon as you hit the water.
 si cooke 20 May 2010
In reply to cosreba: if people keep throwing stons in, the water won't be deep enough eventually because of the pile of rocks on the bottom!
OP cosreba 23 May 2010
In reply to cosreba: Did the leap! the flight time was awesome! however landing was very very painful. Takes a moment of madness to make the leap at the top, glad ive done it but never again.

Some fellow doing a 172' dive with somersaults...

He does the jump just after 3:00.

impressive! though my question is this: if that equalled the world record as it says on the video, then why on earth didnt he go a foot higher?! cant be much difference between 172 and 173 feet!!

 pete3685 23 May 2010
In reply to cosreba: I did Nickys years ago. Awesome flight time and speed (I worked out I was doing close to 50 mph as I hit the water. No injuries, but I do remember opening my eyes underwater and thinking how dark it was. Tried blowing bubbles to work out which way was up, but couldnt see them! Luckily,I floated up and broke the surface just as I was running out of air! Was thinking about jumping off the Castell Helen halfway ledge, but never did it.
 Al Evans 24 May 2010
In reply to pete3685: The Castell Helen halfway ledge jump was in vogue in the (I think) 70's, as were one or two other dodgy jumps, I think now some of them are DWS venues, e.g Freeborn Man.

It was Dave Williams who first did the Castell Helen one but I believe he did it as a proper Accapulco-style dive - none of this wimpy jumping stuff.

So what you really need to do is jump ON a diver.

I did this jump years ago, you need a mate to kick the water up (break the surface tension) it eases the tremendous slap a little!!!
