This Instructable will show you the how to build and fly water rockets. Featuring two stage rockets and drop away boosters, and also some basics.
This instructable is based on my knowledge of water rockets, that I have learn in the past few years.

I am not responsible for any damage you infict on your self or others from launching or building water rockets

Have fun building and flying!

Step 1: Lets get Started

A water rocket is propelled by pressurised air forcing water down though a nozzle. This creates thrust.

If you took a standard two litre fizzy soft drink bottle and pressurised it to120 psi the rocket would reach about 100 or so feet.

But then if you took 2, two litres bottles and pressurised it to 120 psi again the rocket would go about 150 feet or so because the rocket has more air in it therefore creating more thrust. The rocket will only go 50 feet more because of the added mass. You can stop this by making a two stage rocket. A two stage rocket will work better because it would not have to carry the full payload on all of its flight.
<p>i cant understand how the parachute will open ???<br></p>
<p>there is no parachute. you just let it crash, make any repairs and go again</p>
<p><strong><em>WOW</em>,</strong> I have built bottle rockets before, but, this is <strong><em>AWESOME!!!!!!!!!!!!!!!</em></strong></p><p>10 out of 10</p>
<p>Can someone please make an equipment list for this? It is just simply frustrating to through the whole thing and pick each piece of equipment out one by one</p>
<p>oh i made it some years ago later </p>

<p>I know you have heard this same thing many times before, but I'm sending you this message because I feel you can do better than this!</p><p>Whenever, someone puts &ldquo;Copyright[insert name/date here]&rdquo; embedded <br>in a photo or creation, that person is really doing nothing more than <br>alienating their audience. I fully understand why you have done this. However, I <br>feel in doing so you have tainted your otherwise-good tutorial. </p><p>To put it plainly, viewers just don&rsquo;t care where your ideas <br>came from or who the first to think of it was. As long as the tutorial contains <br>enough clear and quality information to complete the project, and the viewer is <br>not offended by such content, they will usually give positive feedback. What <br>you have done here is inadvertently offended/alienated the viewer by using a <br>copyright stamp, they are most likely offended because the use of a copyright <br>stamp usually denotes the expectation of payment due to its common use in industry <br>to prevent copy without consent. Let&rsquo;s be honest, nobody likes to pay for <br>things, so as soon as somebody sees this they will probably lose 50% of their <br>interest in the project (especially when browsing a free-for-use content site <br>like Instructables.com).</p><p>Another factor playing into this is the assumption/doubt <br>that this is a legate copyright. If you have indeed gone through all procedures <br>to acquire such a copyright, I&rsquo;m sorry to break it to you, but you are wasting <br>your time! These allegedly copyrighted ideas/illustrations are easily replicated <br>without a copyright stamp by simply placing a white square over the affected <br>part using common software such as MS paint. Although illegal, this is how many <br>works are stolen and claimed by others to be their &ldquo;original work&rdquo;. If these <br>copyrights are false or you do not rightfully own the content covered, you are probably <br>in violation of patent law. Either way, all you have done is turned off your audience <br>from any further business with you, the author due to your choice to exhibit a <br>copyright.</p><p>Yes, in a perfect world, everyone would/should acknowledge <br>all the sources from which they have pulled. In reality this just not practical. <br>First off, nobody is going to be able to recognize each and every individual <br>who may have contributed or had a similar idea. This is because on almost every <br>simple project (such as those on Instructables), nobody knows where all the <br>ideas came from. For example, Leonardo da Vinci is commonly credited with <br>inventing the parachute. Although this was never entirely his idea, he may have <br>put his own spin on it, creating his version, known in the history books. This <br>was most likely done by compiling numerous other concepts, created by others, <br>most of which even he wouldn&rsquo;t know the origins of. He may have even incorporated <br>concepts that he was familiarized with during childhood by his mentors, years <br>before he first thought of the invention. It is this type of idea-building that <br>has driven millenniums of technological progress. </p><p>Bottom line is, unless your idea is a complex piece of <br>highly-developed, never-before-seen technology, and is at-risk of being copied (for <br>profit) by another party, copyrighting it is a waste of time and is frowned <br>upon by your audience. You have presented these ideas on a website known for <br>offering free-to-use tutorials/content, in addition to the fact that you have blatantly <br>told anyone and everyone how to build your device. These facts show that you <br>are intending for your project to be free-for-use/public domain. And therefore <br>should never have been copyrighted.</p><p>The part that disappoints me the most is that you have used <br>ideas from another site (no credit given to Air command Rockets) and all the <br>while expected us to give you credit for your ideas. Note that Air Command&rsquo;s boosters <br>also function by being &ldquo;held on by the upthrust of the bottles&rdquo; (step 14), (see <br><a href="http://www.aircommandrockets.com/howitworks_1.htm#DropAwayBoosters" rel="nofollow">http://www.aircommandrockets.com/howitworks_1.htm#DropAwayBoosters</a> <br>for comparison). It would have been fine for this site had you left it at something <br>like &ldquo;I have created boosters that fall away after the trust is depleted&hellip;&rdquo;. But <br>you just had to dig yourself a trench by saying &ldquo;These drop away boosters are different <br>to Air Commands.&rdquo; (step 14) &ldquo;Professional&rdquo; indeed!</p><p>oscarthompson- My suggestion for you is to: </p><ul><li>Remove the false copyrights if they are illegitimate<li>Revamp this Instructable to include citations <br>where necessary, OR re-word it as not to claim ownership of any questionable-owned <br>ideas.<li>Try to be more considerate of you audience in <br>future postings by not attempting to copyright things that are to be posted as <br>free.<li>Stop trying to be a company, you are a man with ideas, not some business trying to make a quick buck! </ul><p>As for anyone thinking that copying ideas and claiming them <br>for their own is okay:</p><p>Copyrights are in place to protect those who have worked <br>hardest on their intellectual property. An example of a clear violation of this <br>would be somebody copying an entire Instructables, such as this one, editing <br>out the author&rsquo;s name, and re-posting the ideas represented as under their own <br>name. Even though this is not copyrighted, it is still not your property, and illegally <br>copying it as &ldquo;your work&rdquo; is considered plagiarism (which can also be illegal). <br>A good rule of thumb is to go with your gut-feeling, if you don&rsquo;t truly feel/know <br>it belongs to you, then don&rsquo;t use it, or at least don&rsquo;t take credit for it as a <br>&rdquo;completely new idea&rdquo;. Even better would be to hunt down the work, from which <br>you originally got the ideas, and properly cite them. This shows your audience that <br>you value their interest and encourage them to find out more about your <br>project. One last point to consider, is to not try to label a work as private <br>property, when it is supporting content intended to be freely used by others, <br>on a regular basis. That&rsquo;s not a law, it&rsquo;s just polite.</p>
<p>that looks intense</p>
<p>Dude is this okay.</p>
<p>What are you doing?</p>
<p>but cool</p>
cool rocket
do you actually own the copyright to these diagrams, i highly doubt you have gone through what is needed to have the copyright for them and putting that little &quot;copyright OscarThompson&quot; in your pictures doesn't actually do anything
don't be mean to the person it is a good rocket
He is just putting acknowledgment that it is his.
I'm pretty sure you get copyright automatically, even if you don't claim it.
I have only put it in so people can't use my pictures, unless they want my name on it. The my pictures as i drew them on paint, it really doesn't matter too much that i havn't copyrighted them.<br /> <br /> Thanks<br /> <br /> Oscar
hello oscarthompson could i plz have ur email because i have a few questions on specific aspects of the project :) thank you
I use small sections of threaded lamp rod for my water rockets, but I don't know about oscarthompson.
<em><strong>nice project do you have a video of it flying i wana see how it fly's so i know if it worth making</strong></em>
nice water rocket <br>do you have a web site
Unfortunatly not. You should check out aircommand water rockets though!<br><br>Thanks<br><br>Oscar
i like it!! definately gonna make sumthin like this one
verry good ilike
What kind of plumbing coupling?
what with the picture?
how long will the pressure hold
Wow, this is amazing! Keep up the good work!
Wow, nice build!
In the pop-culture, Samantha Ronson is a famous DJ and song creator.

As summer comes, I think that you may do not want to wear <a href="http://www.ugglinks.com/" rel="nofollow"><b>UGG Boots</b></a>. It is said that if you want to put your ugg boots up, you had better place a support plate into the <b><a href="http://www.ugglinks.com/ugg-bailey-button-c-66.html" rel="nofollow">UGG Classic Boots</a></b>, if not, you may also use newspaper. The general newspaper is the best choice. When you use it, you can feel that it can help you avoid moisture and odor. You don&rsquo;t need to fill up, you just need to hold up slightly and to leave gaps. From <a href="http://www.ugglinks.com/" rel="nofollow"><b>UGG Boots Outlet</b></a>.
What kind of glue should I use<br />
I used <a href="http://www.tooled-up.com/Product.asp?PID=977&amp;Referrer=froogle" rel="nofollow">bostik soft plastics glue</a> and it works fine for me. Although you can use <a href="http://www.gradyshardware.com/Henkel-828472-PL-Premium-Polyurethane-Construction/M/B0002YV81Y.htm?traffic_src=GB&amp;utm_medium=CSE&amp;utm_source=GB&amp;id=uk" rel="nofollow">PL premuim</a>, but this is a bit more expensive and harder to get hold of in the UK, but it may give you better results.<br /> <br /> Oscar.<br />
who cares if he has a copyright?!?!? this is a great instructable that i used to spend a few hours with my daughter AND&nbsp;an instructional speech for my speech class. but the instructions you put on here were clear and easy to read. and i researched the launcher online for several hours and i believe this to be the best one.<br /> <br /> i used the 2 bottle design and i used gorilla glue (which is stronger than hot glue). the thing reached 15 to 20 feet in the air and the reason for this failure was my choice of glue. the glue expanded like it is designed to BUT&nbsp;this glue is not a good adhesive for the plastic in the bottles.<br /> <br /> i can see the potential if i just follow instructions (this was a problem for me growing up). i always think i can improve the process, but once again i am wrong. but my daughter had an awesome time, i had a great time, and we got the whole family together for the launch so the project was still an overall success. i will be building bigger and better in the near future.<br /> <br /> thanks for the great instructable oscarthompson!<br />
I used to make make water rockets when I was a kid.&nbsp; All I ever&nbsp;used was&nbsp;a 2 liter bottle, duct tape,&nbsp;and the valve stem from a tire.&nbsp; Drill a hole just slightly smaller than the valve stem in the plastic lid and jam the sucker through it as far as you can, wrap the bottle with duct tape (just one layer is fine) - this is a &quot;better safe than sorry kinda thing&quot; -&nbsp; never had one blow up.&nbsp; Fill the bottle about 1/5 of the way with water, use a hand pump or air compressor to add about 45 psi, turn upside down and unscrew the lid.&nbsp; Mine usually went above 100 feet easy, of course I used a bit more pressure.&nbsp; ;)
Thanks, you made my day !<br />
I'm gus this does not go high&nbsp;&nbsp; it looks to big to go high!!! But any way sweet!!! 5stars!!!!!!!!
Can we see a video of your big rocket?
what do you mean with rubber bung in the part list of step 10
rubber bungs like the ones in wine bottle's but rubber. Type it in to google images<br /> <br /> Thanks <br /> Oscar
I see thanx
i like the idea but i don't konw anything.<br /> How can i do for fill the boosters?<br /> do i have to put their a valvle each?<br /> and are the boosters gonig to fall down?<br /> if yeah how will i do it ?<br /> thanks for the &nbsp;ideas.<br /> <br />
You can fill the boosters by putting the water in the top of the bottle. The bicycle valave will help prevent leakage.<br /> The boosters will fall down when the thrust of the booster can no longer beat the air resistance thus gravity pulling the booster down.<br /> <br /> This can be achieved by making&nbsp;three of the launch mechanism's just on one Pad (&nbsp;two for boosters one for main)<br /> <br /> Oscar
good so far, but the diagram for this step cannot be viewed properly at the current size, and even when viewed at the right size, it is very hard to understand.<br />
This is AWESOME!&nbsp; Its the John Holmes of water bottle rockets.<br />
what is the materials list for this project
Which part of the project?
all of it <br /> we need to know the materials list for everything SO WE&nbsp;CAN&nbsp;DO&nbsp;THE&nbsp;PROJECT...<br /> AND&nbsp;PASS&nbsp;OUR&nbsp;CLASS
First your going to need about 10+, two l bottles to start<br /> <br /> For the launcher you will need;<br /> <br /> qty part<br /> 1 1/2 inch wood (any type)<br /> 2 10mm bolts<br /> 1 10mm metal drillbit<br /> 1 10mm wood drillbit <br /> 6 10mm nuts and washers<br /> 1 presta bike valve (you can get this from an old inner tube)<br /> 1 rubber bung<br /> 1 bike pump<br /> 2 tent pegs<br /> 4&nbsp;L brackets<br /> 1 mending plate<br /> 2 nails<br /> <br /> For rockets you will need;<br /> <br /> corex (corregated plastic)<br /> ducktape<br /> pl premuim or another pressure rated strong adhesive<br /> ping pong balls<br /> 1.25 l bottles<br /> <br /> For parachute mechanism;<br /> <br /> You can use my nose cone drop of deployment or a <a href="http://waterrocket.uh-lab.de/tomytimers.htm" rel="nofollow">tomy timer release</a>&nbsp;mechansim avible with the link.<br /> <br /> For the tomy timer release mec you will need;<br /> <br /> Tomy timer (wind up toy)<br /> plastic or synthetic fabric<br /> string<br /> glue<br /> rubber band(s)<br /> <br /> For the staging (which would be advised to be not for biggerners)<br /> <br /> 22mm pipe<br /> hinges<br /> basla or ply wood<br /> m4 bolts<br /> string<br /> tomy timer or servo <br /> <br /> Thats about it, But how long do you have to do this?<br /> And if your just biggening&nbsp;water rockets&nbsp;I would advise you to not do multi stage or drop away booster rockets.<br /> <br /> Thanks<br /> <br /> Oscar
