Water rockets are fairly new to water warrior technology. To reduce our carbon footprint, water rockets are built using plastic bottles. This forum topic talks about the operation of standard water rockets and launchers, how they can be used in a water war, construction of water rocket launchers, rockets, and add-ons like water balloons on the tips of rockets, ammo clips, and grips as well.

I'm interested in making a pneumatic potato launcher, I've found plenty information on that but I want to hit a target 255 meters away at an angle of 45 degrees. I calculated that I would need an initial velocity of approximately 50 m/s without wind resistance. The object being launched is an average sized potato under normal weather conditions. With wind resistance, what initial velocity will be required to hit the target? Please explain the process by which you came to the answer so that I may use the same method in future endeavors with different angles and distances. Also, just how much pressure would be required to launch a potato and achieve that speed, and to what specifications would the launcher need to be built i.e. how large the gas chamber will need to be, length of barrel, etc...

Problem-i am building a large knex bazooka that needs a customized firing system. it needs to hold on to the projectile with some sort of fingers, which are to release when triggered from the rear of the holder, and the holder needs to ride in the rails of the gun, and it needs to be able to attach to a length of string. operation is-latch projectile in claws, pull both claw and projectile into barrel, pull to rear of barrel, stop motor, pull trigger, which through a series of levers will push to release on the back of the claw, launching the projectile. can anyone create such a claw as im stuck. ive got the gun, motor, gears, and projectiles, but i need some claw befor i build the trigger so they'll be compatible.

I was watching the military channel, and I saw the M32 grenade launcher. I really want to build something like it with knex. But here's the problem: I have yet to find a grenade that can fit in some sort of barrel. I'd use Carlz's grenade, but the rubberbands on the outside of it would GREATLY decrease the range. We need to make a smooth grenade, any ideas?

I need ideas for the firing system for a rocket launcher. I have some pictures of what i have built. But i do not have a firing system for it yet. Any ideas would be appreciated. This is a knex rocket launcher that used the Air Ball Tower tubes.

Hello everyone this is an idea i had and i am going to try and do. The idea is to take one of the Wireless USB Missile launchers(seen here: http://www.newegg.com/Product/Product.aspx?Item=N82E16800997039) and connected it in some way to one of the trip bells(often seen at stores). Instead of setting the bell/alarm off i want it to send the singal to the USB Launcher and have it shoot at a set location.If anyone can help direct me as to what i need to buy and do to make this work all help would be appreciated.

Recently i was glancing at my halo 3 owners manual and was on the page w/ all the weapons, when an idea struck me in the head. Why not build a missle launcher? it would be a first to the site, i mean right? If you like it maybe i will post. don't forget to rate and comment!

I heard from sscoasters.net that someone made a Magnet brake. Now I wonder if you can make a LIM launcher and some people said that you need electronic magnets that turn on and off the launching machine. I was hoping to find some information for a simple thing like this. Maybe someone can make a Electric Magnet from house materials.

A semi auto rubberband launcher. really a semi-auto and a by un connecting 2 peaces you can quickly switch to full-auto. uses a new triger system that i thought up. lets the gears turn only when you push the triger. working on instructions. i also made duel rpg pistols useing the same firing system. i will put those in the instructions.https://www.instructables.com/id/semi-auto-knex-rpg-twin-pistolsrifle/

Splodie launcher: I just made this gun, it fires custom splodies. It's range is about 30-50 feet (depends rubberbands). And It will hurt if ou get shot (ask my friend). Some of the parts are from excisting guns (barrel, trigger...) The trigger mechanism is a bit crappy but works, so if anyone has some tips, plz tell me. Splodie rocket: This is a rocket that holds 5 splodies in it, I still have to make a launcher for it. And I'll do that this weekend. Greetzzz, Infinnion UPDATE 8july: I added some photos of final version. The launcher has now a good trigger mechanism and the barrel is shorter (less dragg), the instructable will be post this week (if I have enought time), and I wasn't able to make a laucher for the rocket. I've now devloped another rocket, so I may make a launcher for that. WARNING: I am not responsible for any damage to urself, your home, your cat :P, or ur knex parts. So please dont point at people or animals, except for people u hate :p, no i'm serious.

Many people have used sprinkler valves for a dump valve to release the air. I have made a launcher that used one of these and when I hook the air up it releases it all before I can hit the switch causing a pre-mature fire. Does anyone have these problems. I think it can be fixed by adding the air in slowly rather than hooking up a quick connect coupling like I am now. Any help would be appreciated.

A golf ball will traver about 3X farther than a smoth round object . This brings a spud/rifle to a whole new level.. Golf balls now come with 350 to 450 dimples to disrupt the lamar flow and decrease drag. The ?? test guys did this to a car and got 10% better gas-milage on their first try. I've thought about this for a longtime now .., I need some help tho,.or I wont ever get to It. There is a recient article here on a hi power or long range spud rifle that looked good for a launcher, but it mite now be strong enuf for a 45 grain ball? Some ball did come with just a band of dimples so the ball would stabllise in flight and not climb or divert from the spin all golf clubs have built into their faces 7degrees? I believe they were outlawed since they would be more accurate on drives. It mite be good for this launcher tho? Thanx

One thing I really dont get is people just rating knex guns by looks or because they like the user who posted it, personally I only rate guns that I have built, and the only gun on this site I have completely built was shadowninjas assault magnum. oh heres pics of the fsastr (firestorm assault rifle) sorry there is no full pictures I haven't loaded hem up yet its a true trigger assault rifle removable yellow rod mag attatchable oodammo grenade launcher with top railspicture notes1-the mag2-looks a bit like a halo battle rifle attatchments are foregrip and carry handle/sight3-assault configuration short sight and oodammo grenade launcher4-oodammo in launcher5 grenade launcher

My Bungee Bazooka along with crreed's Grappling Hook Launcher were noticed by the folks at Popular Science magazine, and they published snippets about both projects in the March 2012 issue (page 66). Here they are at popsci.com. I thought this was awesome!

Ever wanted to know how to build a twin water rocket launcher? Have some expert advice on hand? Feel free to comment and help build a full metal, high PSI twin launcher. I am looking for assistance/advice you may wish to input. I was hoping to build a substantial base for launching multiple water rockets. It has a quad manifold so further expansion is possible. As you can see from the parts, it is very simple. I still need to add a isolating valve to stop water back flow into my pump (which will be located at the end cap, after the gate valve. The release mech has yet to be designed also. Australian gardena hose quick connects are the base for this rockets release system. I hope that is not too confusing. If it is, ask and I will clarify my babblings. Thanks for the assitance

It's winter and snow is everywhere (well where I live there is) People are sledding and making snow angels. And of course my favorite part- Snowball fights. Snow in ball form whizzing thru the air towards people. Me loving to build stuff and loving to improve it to, I wanted to make something that could throw snowballs better than any person. I have an idea for a couple launchers and cannons but I want to see other people's ideas. So post anything, a launcher, a cannon, a catapult, a chucker. Anything that can accompany someone in a snowball fight. So people POST.

Hey everyone, here's an update video and pictures of Cataclysm. I finished the ball launcher, added the wheel lift, and built the chain path lift. The video doesn't show the arm lift working because I took the batteries out of the motor to prevent corrosion. The ball launcher doesn't send the ball all the way up half the time, so I'm going to have to redo the track coming out of it. I also need to add a gate at the bottom of the arm. Click here for more pictures! Video: don't forget to watch it in HD! Enjoy!

At my school they have a program called launcher.exe on all of the shortcuts in the start menu. so if I wanted to open SketchUp for example it goes "do you want to run sketchUp (licenced to SCHOOL NAME) yes or no?" I looked at the shortcut and the target is "//admin/programs/launcher.exe sketchup.exe" Any ideas what the code is behind this. I want a program that will do something simmilar but let me change the app it opens using the commnad line.

Hey, I'm wondering if anyone knows of mods for the Nerf Raider that don't fire Nerf darts. I've modded a few nerf guns, but I'd like to repurpose my raider to shoot something else. I'm looking to make it like an airsoft gun or rocket launcher-type gun. Any and all suggestioins are appreciated. Thanks!

Good news! I have been seeing whether or not I will be able to make a model Saturn Rocket for the challenge. I did bottle rockets way back in 2006, but all the stuff, Including the ubertastic launcher, is gone now. Good news is, I have found a way to splice bottles, and tested it today. Works pretty good so far, and I will be making a full scale test rocket soon. I don't have my launcher that was super awesome, but I do have a small Clark Cable launcher, hand held version. I do plan for my Saturn Rocket to not only have an Instructable, but an Instructable detailing splicing bottles, adding a parachute system, and adding a small package (in my case, the small lunar ship). If all goes well... I should finish before The end of the contest.

*********I have updated my design since posting this topic. The video is the more current design than what is written below.********** I came to the conclusion that using capacitors to provide the power for a coil gun is a stupid idea. A bold statement I know. The reason is that they are big and heavy, take time to charge, and need charging circuits. Also, the sharp rise in current that comes from capacitors is bad unless you are making an induction style coilgun, because the induced currents will hurt efficiency. If coil guns are ever going to be a practical hand held weapon it will need to be lighter, simpler / less delicate, and more powerful than what you will find on the internet if you look up coil guns. A rate of fire that is competitive with conventional guns will also be needed if a coil gun will be used for anything other than target shooting or maybe hobby hunting. So I designed a coilgun to meet these requirements. Visit my website for a full explanation of the design: http://www.ourbadscience.com/#!em-guns/cwjy I realized that a coilgun would not be a practical infantry weapon until batteries are more advanced anyway, so that just adds to the list of why capacitors are out. It will be powered directly off of the batteries, and have many coil stages. This allows a very high rate of fire. To get that rate of fire with capacitors you would need several capacitor banks charging at offset times, so after each bank fires another is just finished charging. That would be terribly bulky. The lower voltage from the batteries will give comparatively slow current rise in the coils which normally would make the coil timing weird. I plan to use an unconventional coil timing though. All the coils will be activated at once, and the coils behind the projectile will be shut off as it passes them. This will have several advantages: -The coils will only be powering up for a split second at the beginning. Most coils will already be at full power when the projectile gets to them (that is not the case in most coil guns). -Induced current will not be any issue. -Since the coils will all act as one coil, the projectile will be drawn toward the center of all the coils that are on. Timing of the shut off of the coils will not need to be perfect. This will be a pre-tuned passively timed system. I want to use a small adjustable electronic timer for the switch-off timing. This will require some work in the initial adjustment of the timing, but even actively switched coil guns (with optical sensors or something) require that. the advantage of a passive system over an active system is cost and simplicity, and you can pack the coils tighter on the barrel if you are not putting a sensor between each stage. That matters with 23 stages! As I said check out my website to see more details and pictures for this and other projects: http://www.ourbadscience.com/#!em-guns/cwjy
