Step 6: Fill the soda bottle with filtered water and ~10 mL (2 capfuls) of bleach. Cover with its original cap

(Filipino: Punuin ang bote ng filtered na tubig at ~10 mL na bleach (2 sukat gamit ang takip). Ilagay ang takip.)


<p>How do they make this thing work at night though? In the video I saw at literoflight.org the people have a tube like thing in the bottle with something giving off the light, and there has to be something retaining the energy during the day. This would be a great science fair project! Anybody know how to do this? There is more to it than just the bottle, water, bleach, holes, rivets and sealants. They are using these at night.</p>
<p>The literoflite ones use a small solar panel to charge up a battery which then powers the bulb at nite.</p><p>If you look carefully you can see the water level at the halfway mark, so they are using water as a light diffuser. The tube bit is most likely insulating the bulb wires that run down in the water to stop corrosion which could change the water clarity.</p><p>This version is a daytime only one with no batteries, solar panels or bulbs.</p><p>Just in case you were still wondering. :)</p>
Can we use bleaching powder in it !
<p>Although I'm, let's say disappointed with the lack of understanding in the comment about crowd funding, I have always loved this idea. However, It does need some improvement. In Australia the sun will cause the plastic to perish in a single summer. Glass would be a better option, as would a clear liquid that ISN'T prone to grow algae. I have wanted to install some of these in our sheds, but I also have experience with a Solatube, and find that to be a much better option. Now if someone could find a way to use that technology adapting it to re-use of materials, THAT would be brilliant. Crowd funding is not something to blow ones nose at! It has been used by some greedy self important jerks true,as is anything that they can jump on to try to accumulate &quot;points&quot;... but it has also helped others with ideas that DO seek to make products that HELP the poor, the disabled, etc.. People should not be put off the idea of crowd funding simply because of a few with bad intentions. People should be encouraged to think about the need for the product, and do so without greed being the motivation for investing. Invest to make this world a better place for everyone. THAT is the reason for crowd funding my friends.</p>
You do know that bleach kills algae, right? Also, a certain type of plasticbottle must be used. That is because itlasts longer. I believe that this video will help you: https://youtu.be/i5YQ4t5apPM
<p>what is Solatube?</p>
<p>Google it?</p>
<p>What is Google?</p>
<p>Here you will find some information:</p><p>http://lmgtfy.com/?q=Solatube</p>
<p>Is it worthy? How much investment need for that?</p>
<p>I think it is wonderful that people are exercising their initiative in helping themselves. Why would I want to hinder that by contributing? People beg Jesus for miracles; beggars beg for money; neighbors ask questions instead of looking things up. If the boy scout troop wants to go to Hawaii, that's great! Go! Why are they going around asking people to get them there? </p>
<p>What are you talking about?</p>
lol right!?
<p>Saw a documentery about this on tV about four years ago, the idea has been around for quite some time and has been used all over Africa and South America, as well as Malasia.</p>
<p>Just a question: what if I don't have a Bosch lithium-ion cordless drill?</p>
<p>Just a quesstion: Why are you being a jerk?</p>

<p>This a very thought provoking instructable.... How would glycerin behave, a little oil? So many more avenues for inquiry. Thanks for the challenges. </p>
<p>beutiful project </p><p>I want to help them there if i get the change</p>
<p>Awesome Project....</p>
<p>this plastic bottle light is a remake on a centuries old idea used to illuminate the interiors of darks boats. they are called deck prisms. </p><p>see: <a href="https://en.wikipedia.org/wiki/Deck_prism" rel="nofollow"> https://en.wikipedia.org/wiki/Deck_prism</a></p><p>still its nice idea.</p>
<p>What if you use a glass coca cola bottle, with its curvy form. Will it work the same?</p>
What kind of bleach are gonna put in ? Just like commercial bleach?
<p>cool but this soda solar bottle bulb doesnt work on dark night. Moonlight maybe dont now. </p>
<p>Can not work at night .....no Sun</p>
<p>1 ) Chlorine in bleach is to prevent water going green from Algae.</p><p>2 ) Can not work at night .....no Sun </p>
<p>Great for desert areas... Not direct sunlight, yet you are lighted up with shelter... If you need... Then just grab your AC and just live your life out.</p>
<p>LOL if you had AC, you could just plug in a flourecent light bulb...</p>
<p>Hm... Can you do this without busting your roof open? Maybe... Place them on windows? Except it won't work at noon... Then, another amazing thought... What if people wayyyy back then could do this, and they could have made a clock out of it? like... think... If it went dark in the room, it was noon. If it was bright on one window, it was morning, on the other, evening... Then when it was dark altogether, then it was night.</p>
<p>Amazing idea. Free. Unlinke the Crowdfunding ideas which seek a millions to fund the development of a product the poor cannot afford.</p><p>This won't work under many non-solar conditions but when it does work it must be a miracle for these folks.</p><p>Now if the liquid could be made to store the light similar to fireflies and fish...</p><p>Have you tried using longer tubes, for instance an eight foot tall pipe in the corner of a room? Or a long clear plastic pipe and maybe diffuse its surface? Plastic fiber tubes are used to transfer light from one end to the other.</p>
<p>AMAZING! WHAT A GREAT PERSON THIS IS!!!!!!</p>
<p>My grandfather used this trick to light a work area in his barn when I was a kid. </p>
Can it be installed on a roof made of bush? Just like huts. I doubt that heating can lead to accident but i am not sure about it. I want to install it to needy at my native place
<p>How long will this last? I don't mean how long per charge. Will the water and bleach have to be replaced, and if so, after how long?</p>
<p>Dear </p><p>I have tried the same but It's not work. may I was wrongly do the procedure from filling water + bleaching powder. I want to know more descriptive information i.e. how much water and bleaching powder required and how much time it will keep in sunlight. (i.e. quantity, time required)</p><p>is any gas is generated in the solution ? questions are created while bleaching powder is mix in water </p><p>in anticipation</p>
Well if there was any gas that is generated then simply puncturing a hole in the top of the water bottle would solve that but I don't believe there would be unless you had urine for a yellow light which mixed with the bleach would create mustard gas and kill you
Do you have to put GI sheets? Please answer. Thanks.
I don't think so that is most likely just a choice because thats what alot of sheds roofing in made of im sure you could use sheet steel
<p>May I use the photos for a EXPO tast? </p>
<p>If you are in a temperate climate where freezing during the winter months may be a problem {tool sheds, garages, &amp; etc.}, DON'T use water as you medium. To avoid the medium from freezing, JUST use an edible grade of mineral oil (~$5.00/Liter) as your medium! It has a freezing point of -20 degrees F or -30 degrees C. The refraction of the light would not be much different!!</p>
I would add some salt and alcohol too, if it freezes the bottle will suffer less forces because the water will not freeze which results in ice; ice has a lower density than water so the volume will go up, stress on bottle where the bottle is inside the roof-panels. Adding fluorescent components wiil make it glow a little, not enough to see what you would be doing but maybe nice as an orientation light. These kind of bottle lights can also be placed in a wall, I saw it in one of the Transformer movies near the Pyramids where megan and shia hide and are found by a bug-transformer, these look more like glass wine bottles glued in a cement wall, looks pretty cool too!

Great how/where can l get bleach. My email jopeyemi60@yahoo.com or stanleyboy39@yahoo.com pls help me
<p>You can <strong><em>ALSO</em></strong> use some finely cut up pieces (1-2 oz.) of <strong>copper wire </strong>placed in the solution if you absolutely don't have access to any liquid chlorine bleach!</p><p>Another substitute is 15 ml of an <strong>Iodine Solution </strong>instead of chlorine bleach may be used. Iodine can be found on most medical shelves in many types of stores!!</p><p>Both of these things can help to prevent the growth of <u>algae</u> in any water in the bottle!!! </p>
<p>Clorox</p>
<p>will indirect solar radiation be enough to light the bottle? for instance could this technique be used to light a room without a window by placing the bottle in the wall between the rooms?</p>
<p>can you use it as a amplify for lights???</p>
