[The Dirty Filipino]

I'm working on a project and I'm in need of something that I think exists, but I'm not sure how to make/acquire it.

I need a metal (or some other hard material, one that can remain rather straight while having water run over it) that, with an electromagnetic pulse (or something) that will cause the material to recoil taut. Think of it like I have a fruit roll up that is unwound. I need something that will allow the fruit roll up to return to it's packaged position without the use of any conventional mechanisms (like an automated roller, etc.)

Is there anything like this?

What you're describing sounds like a bimetallic composite of some sort. The ones I studied in material science responded to thermal energy though and not an EM pulse. It basically straightens when heated, but when it's cooled, it curls up because one side of the strip has different thermal expansion properties.

http://en.wikipedia....imetallic_strip

However, these tend to curl only slightly.

Perhaps a snap-bracelet shape, combined with the bimetallic properties SL mentioned, so that on heating, the strip will flatten, removing the shape that holds the strip extended, and causing it to roll up again.

It'd have to be mechanically straightened out again, though.

Do you have an engineering background of some sort? Just wondering because of the topic title.

Nope

[ShadowLink64]

Nope

Hmm... science background then (physics or chemistry)? Or do you just read a lot, or do lots of hands-on projects, because that's possible too.

I have an A level in physics, AS in chemistry.
I do read a fair amount, I suppose, though less so now than when I was younger.
And yeah, I love building stuff. I just built myself a home studio:

Yea I considered Bi-Metallic properties however I threw that idea out the window because the purpose to what I need it for is meant to be used outside in an unsheltered environment, therefore rendering temperature control too difficult to be worth creating.

If you're really wondering what the project is, it has to do with pool pumps. My dad, being the ass that he is, goes and tells his friends that I'm the Thomas Edison of the future, leading me to my current situation. I'm going to assume you all know how water pumps & filters operate. Anyways, there's a backwash valve on these and most older pool pumps don't have tubing running from that valve to a waste area, so most people just use rubberish hoses to carry the discharge 10+ meters away. I'm looking for some sort of material to run down the length of this hose that will flatten when needed (I would say when pressure from water is put on, but the rate at which the water releases out the pump is not really controllable, and will break the material if it becomes too pressurized) but will recoil back to a solid shape when done. I know people have hand rollers, but this is for the 'really lazy people' and I'm just doing it for fun. However, if I could accomplish it, and it was an easy task to do, I'm sure I could possibly sell it as well.

Sorry, I should've said anyone that can't beat zachafer on an IQ test shouldn't post.

That's no excuse.

It's like losing a footrace to a snail, when the track is covered with salt.

That'd be far too long for a snap-bracelet style design, then...

I can't really think of anything simple and non-motorised =/

[The Dirty Filipino]

No Joe can't fail me. This is my last resort before I actually have to do research into the matter.

The coil hose is the best way to do what you want but unfortunately it's already been invented.

I don't think 1 1/2" of pressurized water will fare too well being put into a coil hose. I thought of that already but it just wouldn't work with the size of the valve and the amount of flow.
