P.E.T Wall




This was a group project done in my first year of architecture school. The objective of the project was to create a plane (floor, wall, ceiling, partition, anything planar really) out of used objects(our group happens to choose 2 litre PET soda bottles.....1200++ of them). I am not sure people would actually see this and replicate the whole thing,nevertheless i hope you will enjoy it

Step 1: Materials and Tools

2 Litre PET soda bottles, a mixture of clear and green bottles.(we went dumpster diving for a few days to get all the bottles)

Hot wire for cutting foam (in this case used for cutting the bottles)

Some medite to make couple of jig

Hole saw drill bit that would make a hole just big enough for the mouth of the soda bottles

safety mask to protect yourself from the toxic fume when cutting the bottles with hot wire cutter

Step 2: Cut the Bottles

Clean the inside of the bottles and remove most, if not all of the labels.

Cut as many bottles as you wish.

You will end up with four parts, the mouth, upper, middle and bottom.

Flatten the bottle, put it in jig 2 and drill the four holes.

The middle part of the bottle once pressed and flattened will be the building block of the plane, the mouth becomes the connector between individual building block.

Do not throw the upper and bottom part of the bottle, they are essential for the structural integrity of the plane.

Step 3: Assembly

Now that you have amassed a large amount of these bottle parts, its time to put them together.

The assembling of one bottle to another is quite self explanatory.
overlap the flatten and drilled , put the mouth of bottle through the hole, screw the cap on.

to stand the plane up, our idea was to create a pocket in the plane so that it can be filled with the upper and bottom part of the bottle hence creating wider base.

Step 4: ENJOY!

I still have all the bottle parts in the basement waiting for their uncertain future if your'e living in the Chicago area and want to take them away please leave a comment. I hope you guys enjoy my very first Instructables, i will leave you with some pictures of the finished project and as D.r. Stephen T. Colbert, D.F.A. say " EMMY PLEASE!" (or in this case Solar-powered backpack from Voltaic, the Converter please!)

    This is a really great idea--I need a separator for my apartment, but I'm going to try a less rippled effect. I think I'm going to drill holes in the corners instead and wire the pieces together. That way they can be suspended from the ceiling or a framework. Thanks for the inspiration!

    instead of using wire you could make string from the bottles and use that to tie and string them up. Look up "string" from plastic bottles on here. It's an easy ible to do and it's completely green.

    if you get dark colored bottles you could make a wall separator. Thanks for the idea.

    Once he cut off bottom and "upper" he had a ring he did not cut this ring he simply squished it flat making a square which is kept flat by the bolts

    Last pic of Instructable doesn't tell me anything new. Which pic are you talking about? In step three he mentions 'flatten' at least twice. Maybe it only has to be held flat during drilling? He has that nice picture of them stacked in a box, but could be they're not really flat, just jammed in. So, a non-issue? Or maybe you could reverse every other one in a checkerboard pattern and all the curves would cancel out?

    yeah melting polymers and releasing carcinogens, sounds like it doesn't pollute, but it does. we shouldn't equate this ible with recycling, not with the damage it has done to the earth. i'm just saying.

    BURNING plastics INCOMPLETELY (in a fire place or fire barrel for example) produces toxic gases. Simply melting the plastic does nothing other than make it liquid.

    But a dust mask isn't going to do anything even if there were byproducts. Ok so molten plastic does stink, but it's not nearly the equivalent of burning it wholesale. Use a carbon impregnated mask is the smell is bothersome.

    Hi ,, how did you "flat" the bottle ???

    I'd bet you could make cool shoji screens with this technique.

    Dear Dude!!

    You had a great idea, way cool, very green idea!! Let me tell you why.
    I live in San Diego, but I do have a huge building in Revolution Avenue, Downtown Tijuana, In Baja California, Mexico.
    Tijuana recycles just about everything that San Diego throws away, and I do mean everything. We do have concerts in our small venue, in which we sell a lot of sodas in plastic containers. We thought of a wall, as a decorative for the huge building, but your application of use to these plastic bottles, is uniquely original. We are going to apply your creativity, we will give you full credit as the designer, we will give credit to instructables, and further more, if you have any more ideas please pass them along to us.
    I am almost on the final concept of creating a large cover up to what it is an old facade for the second floor, utilizing recycle materials, that will also served as ventilation for that second floor, out of the moderate to strong westerly breezes from the Pacific ocean.
    I want to make this building as green as possible from everything recycle, to promote in Baja California, "GREEN: ideas, concepts, construction that will make the city of Tijuana, and the state of Baja greener.

    Thanks a lot!

    Its beautiful! I think that hanging 4 panels, with one strung over the top would give you a very pleasing outdoor space, no? Looks like you've got a bright future in architecture!

    how much do you think it would be to ship the pieces to VT?
