waterproof material?

Can someone tell me what material I can buy that is lightweight, molds like clay, is waterproof and singeproof, and won't break the bank? does such a miracle substance even exist?

Patterned materials..

Trying to get  a jump on my costume this year for halloween and I want to a) plan ahead better, and b) base it on my character in Second Life. Problem is I have been looking at everything from shower curtains to upholstery materials, trying to find a solution, without much luck. Mainly due to the "best" match for what I want to try being an upholstery category material (and even that isn't.. quite right), but I have a lot of yardage involved, and it costs like $27 a yard or something... :p Basically, what I am looking for is something rubber like, so flexible, not overly "glossy", with enough thickness it can be layered, but with fairly fine detailed patterning on it. The original "suit" this is supposed to mimic looks a bit like layers of flexible armor, layered over each other, but both due to the design not being mine, and the prospect of, once done, photoing the result, doing a bit of Photoshopping on it, and "replacing" the in-world version I currently have, I want to make it slightly different. The problem, of course is that I am running into a problem of finding any material, never mind what fits the bill, save for, maybe, buying just smooth, rubber sheeting, similar to inner-tube material, then trying to do something with it. But, how, if I had PVC rubber, do I add texture to the thing (other than, for example, trying to airbursh a pattern over it, which I have zero skill at)? Nearly everything is the wrong material, too big a texture, or just.. not one that will work. Mind, best possible texture would be something like: http://i19.photobucket.com/albums/b194/Dakra/Tech256.jpg But, that ain't happening, so.. something like: http://image.shutterstock.com/display_pic_with_logo/75178/75178,1310971434,2/stock-photo-hi-tech-background-blue-metal-texture-81298300.jpg or even a very small pattern or honeycomb, like: http://images.colourbox.com/thumb_COLOURBOX2412500.jpg Would work. Heck even if I had to decal the stuff on, somehow.. But I am at a loss here as to what material to use (mainly do to finding a place to get it cheap, and not in some insane amount), and if I can get it, how to make the result not look something like the attached image, or better, add the texture to it I would like to see. Any ideas at all?

Material Section

Hi there!I hope this is the right section to post this in, if not then i'm sorry i picked the most probable one (i hope D: ).First of all i love instructables, i'm using way too much time in on this page than i should, but then again if it wasn't or instructables i wouldn't have this cool new Hard Drive Speaker present for this cute girl i like ;)In any case let me get to the point; i would like to suggest a Materials Section for Instructables - basically it would include material stats and an in depth explanation of the material (or component if we're talking tech here, but that's a different area). Here's an example: in an instructable, the author mentions plexiglass and that it needs to be bent. Many don't know that plexiglass isn't class, but an acrylic hardened plastic substance with abilities much like glass (but not quite). Plexiglass can fracture, but wont leave extremely sharp pieces like glass will and it can be bent when under medium-high heat from a heatgun or the like. Also that high friction (from a drill or the like) will cause it to melt.Basically what i mean here is that this section would greatly reduce the time an author spends on making his ible by letting out basic facts. E.g. instead of writing "plexiglass is..blah blah" the user would be able to look up in the materials section and read in depth for him/herself what the characteristics are for plexiglass/plywood/capacitors/batteries and so on.The materials page could be powered by the "burning questions" competition i've seen on this page. I don't think material characteristics fit in ibles because it strictly isn't - it's a data sheet that lets you understand the materials and components you're going to use in an ible.PS: sorry about the lower case i's and the occasional typo or grammatical error i'm not a native english speaker . also i really hope this is the right section to post in...

Materials question? Answered

I know it is possible to by "flexible plywood" or "flexible MDF" - sheet material that can be rolled up in a single direction, whilst remaining rigid in the other. However, I have only found versions that roll with a minimum radius of about 15cm / 6". Does anybody know of a similar material that can be rolled with a much smaller minimum radius, say only 5cm / 2"? It doesn't have to be wood, any easily-worked sheet material will do if it can be rolled in one direction whilst remaining rigid in the other will do.

Tube Material

I started thinking about how the tube material could be improved. Although I love the ghetto look of pringles wrapped in the invincible duct tape, improvements can be made. You could use PVC or ABS for the tube, it wouldnt need pressure rating because Im sure this thing wouldnt have enough power to explode the pringles/tape team. This is rather cheap and you could just glue on an endcap. Then a BBQ ignitor can be threaded in, a ring to define the chamber and barrel and fuel sprayed in! However getting the perfect cost/durability/strength ratio is hard.

Toys/ Materials

Originally Mod Squad was born out of the idea to use donated toys to create prosthetic arms because there is an over abundance of them in the US, they are fairly low cost, they provide a variety of materials, and children would enjoy the way they look as opposed to more industrial materials. However a big concern is their durability. Share your thoughts/findings/suggestions about using toys. Are there other existing materials that are easy to access and would be good to re-use but would also make something that a child would like?

Semi-Solid Material? Answered

I was hoping anyone knew of or had a good suggestion for a material that fits my description. Either a rubber- like material that was softer (more malleable) than rubber, but tougher to prevent tearing or a putty-like material that would change to a firm solid when heat or a current was applied. I need something that can be molded to a specific shape and then hardened to hold that shape, but can later be returned to the non-molded shape.

Semi-adhesive materials

Hi, I'm looking for some suggestions of what I'll call (out of ignorance) "semi-adhesive materials". I am looking for a large sheet that can be folded, or preferably tightly rolled (think a window blind) and a variety of shapes that can be stuck on and repositioned. I've had a look at display felt for use with hook and loop stickers. The felt is quite thick and expensive. I'm just wondering if anyone else has experimented with this kind of project. Flexible magnetic material, or some kind of static attraction or something? Cheaper the better really, but durability is a big concern too. Any pointers in directions to look would be greatly appreciated.

Flexible arm material

I'm looking to make a flexible arm that I can position however I want. I need it to have a fair bit of holding strength in that I don't want it to sag. It doesn't need to hold my body weight or anything like that and it can vibrate or move a little without being a problem. Immediately, two things come to mind: the plastic pieces used for coolant in machine shops that has now become a common material for something like this. The other is made up of stacked plates with a ball on one side and a socket in the other, I wire or something of the sort is put through it and a tensioning knob is used to pull it tight and keep it in place. Commonly, I see these in mag base indicators. I'd prefer to find the second one. Though, I can't seem to figure out what to look for in order to make my own. The best thing would be to find a modular kit that would allow you to make one fo any length (I need one that is about twice as long as a mag base indicator mount). Any thoughts on what or look for or anyone know where you could find something like this? P.s. this is going to be used as a way to hold a small screen. If it works well, I may adapt it to work for other things.

What is a good material for a rorschach mask that i can see out of?

Hi, I soon am going to make a proper animated rorschach mask, ive aquired all the materials i need except for one thing, the actual mask components. I dont know what material i should make the mask from, being as i am using thermochromic pigment suspended in acrylic base, im not sure if spandex will work, also, i have no idea how clearly i can see through any of these materials. What good would a working rorschach mask be if i cant see out of it. The way my design will work is numerous heat pads linked to a controller, the heat pads will heat up to around 40 degrees , just warm enough to get the pigment to change from black to clear, and essentially thats how ill change the mask pattern. ill have 2 masks in a sense, one is a thick balaclava on which the heat pads and wires will cover, so they arent right on my face, then a secondary mask will go over that, though when done they will be attached together.  the secondary mask will be white and will have the pigment on it, it doesnt need to be particularly flexible as the mask will retain most of its shape anyway when not being worn, i just need to be able to see out of it, my design wil lalso include a breathing and cooling system so i dont activate the pigment with my breath, or fill the mask with sweat as it cant be washed. what material should i use?

Braided Wool Rug materials

I have the "ingredients" to make a great braided recycled wool rug: for years I saved wool fabric, bought wool slacks and skirts at Goodwill, etc, then cut them into strips, sewed them together, and pressed them into beautiful balls of wool, all ready to braid into a medium-sized (I think) rug. I didn't feel like doing the braiding part, so I tried finger crochet with the wool. That also works, but it will make a smaller rug (think several door mats). Still no motivation to finish this great recycled project. So, all this prepared fabric could be yours! You could also knit thick, cozy wool slippers. No instructions included for any of these projects; feel free to write your own instructable. Colors include navy blues, lighter blues and grays with a little red thrown in here and there. 11 balls total. Name your price, and pay actual ground shipping.
