Soda Bottle Skylights

I love ingenuity, so I wanted to share this link to an article on a Brazilian machinist who makes skylights from water filled pop bottles. I'm not sure if these would classify as a budget solatube or a twenty first century deck prism.There's also a video, but it's in some obscure foreign language. Portuguese i think.I might add one to my shed...

Plastic Soda Bottle Prosthesis

Prosthethic arms for land-mine victims, etc. War, land mines, and natural disasters create far too many amputees each year, especially in the developing world.  Worse, prosthetic limbs are expensive and hard to come by.  The Center for International Rehabilitation, posting under Instructables username CIRNetwork, has been working to find sustainable solutions:  locally available materials worked by local craftsmen.   Their plastic soda bottle prosthesis is one clear, simple solution to this problem:  a plastic bottle is heat-shrunk to cover a plaster cast of the limb stump.  Different devices can be attached to the end of the bottle, enabling the wearer to perform basic daily tasks.  This type of thing can really make a difference.  Check out the video below, and see more on the CIRNetwork YouTube channel. Want to help?  CIR is seeking donations of mobility aids to support ongoing rehabilitation relief efforts in Haiti.  You can also make general donations to assist people with disabilities worldwide. This post has been sponsored by Pepsi. The Pepsi Refresh Project celebrates the people, businesses, and non-profits with ideas that will have a positive effect on our world.

Pop bottle caps?

I have been saving pop bottle caps for a short time now.  But with the amount of pop my wife and I drink I am going to have them coming out of my ears in no time.  So anyone have any crafting ideas to do with pop bottle caps?  One thing I thought of was to make a computer case out of them.  But maybe I have watched that video of the guy making an 8-bit Zelda case out of wooden blocks too much.

Recycling Soda Bottles Experiments

Test 1: heat gun, "high setting"  Plastic Coke bottle SOFTENS + shrinks                                                                  -  at about 250F * Test 2: Heat gun " low setting** " Plastic coke bottle MELTS enough to  make gooey threads , and bubbles   -   at 450 to 500 F *according to a cheapy harborfreight laser thermometer. Not sure just how accurate it is in the 250  to 500F range. This device seems to read 5 degrees high at the 100F range. ** ironically, the temp is higher on the "low" setting. When the fan is moving less air, that air is hotter. One of the tricks, I imagine, might be to fully melt the plastic without burning it.   Suggestions welcome. Further results will follow.

Ok....  I have literally exhausted every avenue I can.  All I can find are already done bottle cap beads and their finished jewelry.  NO WHERE have I found the instructions on how to actually make the beads themselves.  I need help.  This is driving me INSANE!  Basically you take to bottle caps(and MAYBE you round em out with a ball peen hammer)  Then you weld? glue? them together and drill holes thru them.  I have hundreds and hundreds of bottle caps for this project.  All I need are the instructions to do this project.  I am begging anyone out there who knows of, or has made these please, please...  Write me here, communicate with me telepathically....  Something..  Anything!  I am begging my fellow Instructians for assistance! Thank you in advance!!

How can I measure the pressure inside a bottle of soda? Answered

I'm wanting to know the internal pressure of an unopened bottle of soda.  I'm thinking that I can cover it with an empty balloon and seal it off, then slowly open the bottle letting the balloon expand. Then by approximating the volume of CO2 in the balloon and bottle I'll be able to calculate the pressure of the soda that was in the bottle.  Would this work and any other ideas for this would be appreciated!

How do you make a pressurized 2 litre coke bottle instrument

I have found this video on youtube of this guy who made an instrument out of 2 litre soda bottles. He says he drilled a hole in the cap and put a tire valve through the hole. Then he used silicone to seal the hole, screwed in onto the bottle, and pressurized it. Then he hit it on his hand and other various objects and it produced a very clear sound. I have tries to recreate this, pumping my bottle up to 120 PSI with no results. I noticed that he is from the UK and that his bottles were shaped differently than mine(from America), being more of an hourglass shape. Would this have any affect? Also i noticed that when i was doing it that there was a lower PSI(somewhere less than 100... mabye 80ish?) where i could hear a faint sound similar to in the video. Is it possible that I missed the correct PSI?

Soda Bottle Fusing? Anyone ever successfully joined two soda bottles either by heating fusing or by adhesive glue?

I want to take standard 2-liter soda bottle and join a few of them together into a short column.  The seam or joint needs to be able to hold together and be air-tight and withstand some pressure. I want to submerge the bottles in the water, and so the joints must be able to withstand the forces against the outside of the bottles.  Anyone tried fusing the edges together again; like cutting the bottoms off of two bottles and joining the two cut edges together to form a double length bottle?  If so, how did you do it?  Any special equipment?  Thanks in advance!

nerf gun airtech 2000 and 3000 mod!

Alright... so i hooked a soda bottle up to a nerf airtech 2000 (when i get the stuff for the 3000 i will do that one too) and so now i have a big resivoir and i have a way of hooking it up to a bike pump so i can pump it up to a reasonable pressure and run around and cause pain without tired arms. but the guns pump still works (and gets it up to about 40 psi after 2 minutes of pumping) you use a 4 way coupler WITH HOSE CLAMPS! and use tubing rated for pressure! you have a schrader valve (or similar) and plug the pump on the 4 way along with the out line. (this was done on a 2000, the 3000 may or may not work) DONT HOLD DOWN THE TRIGGER! if you do then much of the pressure will be lost. now you can shoot easily and not be found out by pumping noises) im sorry i dont have a diagram. so when your done... the soda bottle (2 litre is the best! it lasts longer), schader valve, output, and input from the onboard pump should all be on the 4 way coupler and be hose clamped (if not the hoses will fly off and youll hear a loud hiss and be angry) the 2 litre bottle can be consealed in your backpack or be heald under your armpit, glued or taped to the gun, whatever!

Would it be safe or applicable to make Airsoft goggles from soda bottles?

I was recently working on This Instructable when I realized something. I was pumping up soda bottles to very high temperatures, and then shooting them with guns to make them explode, you know, for the lulz. I tried to set the targets off with an array of powerful Airsoft guns, and they would simply not explode, or leak, or dent, or really do anything but go *plink*. These bottles were pressurized at about 80 PSI, and I was shooting at pretty close range (okay, closer that was really safe, but let's just disregard that right now) and nothing happened to the bottles. This got me thinking. I depresssurized the bottles, and went after them at a range of about half an inch with all of my Airsoft guns. Not a scratch. The plastic in these bottles is clear and flexible. My basic question is this: do you think it would be safe to make these bottles into goggles for Airsoft? I have been wanting to build some different masks for a while, to my own design, but the lenses have always been a problem, because they are expensive, inflexible, and cannot be easily cut or shaped. This bottle material is clear, practically free, appears to be just as tough, and can be layered without any visual distortion. What say you, Instructables?

Hanging plants without damaging structure

I read and enjoyed zoe_roses' bit on hanging tomato plants and DebH57's on soda bottle planters. I'd like to try these out.My trouble is that I live in an apartment complex that's pretty strict about ANYTHING we do to our small outside balcony space. I've been threatened with fines when using nails to hang plants outside before, and I think they'd blow a gasket if I hung a soda bottle full of dirt.I'm wondering if anyone has any ideas as to how I could make a hanger without making marks on any structure; essentially, something cheap and removable. Also, if anyone has any ideas how I could dress up the soda bottles (or use an alternate material) so that they look a little prettier, it would be deeply appreciated.Thanks!~Phillip

Shameless self promotion

I'm not sure why I waited so long to post about this but something pretty cool happened to me because of my last contest entry. I entered mySolar Thermally Pumped Hydroponic System in the "keep the bottle" contest. For some reason I didn't win ;-), however, shortly after the contest I received a PM. The PM was from the Harvard Graduate School of Design, they were putting on a conference on Ecological Urbanism and they wanted my project to go on display for six weeks. I, of course, was honored and after negotiating an enormous fee (j/k) I shipped the project up to them.Recently while looking for some more info on the subject I stumbled across their Flickr Pool and two photos of my project. I have to say, it's almost fantastic that a project, composed primarily of empty soda bottles could go from my backyard to the halls of Harvard.And, obviously, this would never have happened if Instructables didn't exist, so my heartfelt appreciation to Eric and the fine people behind the scenes of the website. So without further ado, the pictures.

Using Plastic Bottles and Plastic Containers for Gardening (food) is it safe?

This is more of an answer than a question, well actually a starting point for you do to do your own research. I was just about to start using 2 liter plastic soda bottles and plastic tubs (hydroponics) for my garden. Then I began to wonder about BPA effects. As much as I wanted to use these and recycle, it doesn't look wise. In addition to all the toxic effects of BPA, the out gasing increases with the temperature. ... ie Harvest time over 100 degs and out gasing right into root structure. Cutting or denting plastic also increases the out gasing. Please do your own research about: 1) diseases linked to BPA, especially women 2) how the out gasing increasing with temp increase Please understand I am not here to scare you, but rather to incourage you to do the research
