This video from Johnny Cupcakes features a steampunked pneumatic cannon firing cupcakes and test subjects in lab coats. The cannon looks awesome and the footage is shot at 700 frames a second for some nice slo-mo. It just goes to show that slo-mo explosions of pretty much anything are always fun. But if you do make such a video, please include more slo-mo explosions than people cowering in fear from cupcakes. Explosion at :57 is pretty solid, but the rest is mostly a tease. via gizmodo

After wanting to make an air rifle for awhile I have finally decided to do it. I plan to use 80-100 psi from a bike pump to power it. I plan to use a 1/2 or 3/4 inch QEV (something like this https://www.amazon.com/uxcell-Pneumatic-QE-04-Inlet-Exhaust/dp/B01MYRC509/ref=sr_1_12?ie=UTF8&qid;=1495573897&sr;=8-12&keywords;=3%2F4in+quick+exhaust+valve). Do you guys know if a 2L soda bottle would be a good air tank or should I spend the money to make a pvc or galvanized steel one? Would an air gun connected to the QEV work well? Thank you for your time and help -James

Hi, I'm currently in Year 10 and we have been assigned to make a USB lamp. Now, I'm fine with the assignment only I cannot think of how to shape my idea realistically. I wanted to make a cannon shape, with a sphere like bottom before it curves into a thin neck. However, I don't know how to make the plastic bend into the sphere like shape. It's really difficult and I'll include a picture of my idea if it helps!

I wanted to build a soda shooting fridge canon like this http://www.youtube.com/personalbeerrobot#p/u/3/TVyLuosZ1rY but I don't understand how the cannon in question works. All pneumatic cannons I have dealt with have required pumping, but this one appears not to require pumping. How does it work?

I created a potato cannon that only has straight pieces of PVC.I have seen other designs where the combustion chamber is wrapped around 180 degrees with two elbow pieces thus making the cannon more compact. Does anyone know which design is more efficient as in terms of launch power and speed?

Alright, so ive been into making all sorts of cannons whether they are pneumatic or hairspray, and recently I've been wanting to build a pneumatic tennisball cannon. i came across halve a dozen empty fire extinguishers, i am still deciding if i should use one as the chamber. i am using an electronic sprinkler valve and a 2 1/2" barrel i am also getting a 12 volt (dc) car air compressor (125 psi) and i am going to incorporate this somewhere in the cannon, the air compressor is really small so i could make it built in. i really want to make this cannon portable but i am concerned about the weight of it with the fire extinguisher tank, Any Ideas?

Hi ... in a quandary, and having problems on were to start. Drawing a blank. I need to develope a small Co2 cartridge Cannon that will be placed into a 1/12 scale RC airplane, that will be used to deploy a drouge parachute on command. Can anyone provide me with a starting point? Do you by chance have something all ready in your files that can be used. The drouge shute when deployed, is 72" in diameter, and the package that contains the parachute is 3 x 3 x 3. It needs to be projected at lease six feet from the airplane before opening up. Thank you very much, for any assistance that you can provide. Richard T Leiterman ( KE6RIM )

Im about to show you guys how to take your magnum from quincys instructible and make it into a cannon thing. To turn it into a cannon, have to do 3 easy steps: 1)Take the yellow rod off the firing pin, the firing pin will be the ammo in the cannon. 2)In the front of the gun there should be a orange/black connector that you would stick your original ammo in, take that out. 3)There Should be 3 blue rods in the front of the gun.Two of them are in the very front, and one is about an inch from the front.Take the one that is an inch from the front and take it out. After you do all three of these steps the old firing pin should be able to slide out.Make sure it can slide out, then put it back in. Slide it to the very back of the gun, where it should get stuck because of the trigger.Take a pretty big sized rubberband, and stick it through the middle of the barrel, BEHIND THE AMMO. This can get a little frusterating, so just keep practicing. Once you get it through pull it to the front of the gun and ring it around a rod or something. Now when you pull the trigger the ammo should fly out of the barrel.You can add as many rubberband as you want to make it more powerful.Sorry for giving you a bad picture. My dads on vacation , and he took the camera, so I gotta make the picture from paint.If you were confused on any part of this topic tell me, and ill try to make it clearer for you. Thanks for reading, and please no bad comments.

My friend and I are considering building a spring loaded cannon. The idea right now is to have a pvc pipe for the cannon chamber, and pvc pipes flanking it to hold springs in parallel. A cross-bar will go through all 3 pipes through slits cut long ways in the pipe. The springs will be attached to some point forward in the flanking pipes and to the cross bar, which will be used to pull the springs back and, once released, will launch the dart/ball in the center tube. My research so far - the spring rates of springs loaded in parallel are additive. With 5x 10-in*lb springs, we can produce 667 newtons of force when pulled back 3 inches (springs in question are 5.5 in long) . That will produce an acceleration of 303 m*s^2 on a 1 lb (2.2 kg) albeit for only a fraction of a second. http://www.amazon.com/Extension-Spring-5-625-Long-080-count/dp/B001292S08/ref=sr_1_1?ie=UTF8&s;=industrial&qid;=1257718057&sr;=1-1 These are the springs we're looking at. We'll need to use an even number of springs, so either 4 or 6 (or 8 or 10). So, what do you guys think? Practical? Will we be able to get any distance? Any suggestions? A ROUGH picture is shown below. === are spring tubes, | are handles, and left arrows indicate direction in which springs will be stretched, and the right arrow is a dart flying out of the center launch tube. <----| ===== XXXXXXXXX ------> ===== <----|

Its official, and i accept my defeat, IAC's was rated better and more people prefer it. How will it compare to my newest instructable, my HIGH POWER CROSSBOW. Whose cannon is better, My Light Cannon V2.2, or I_AM_CANADIAN's Heavy cannon V5. They are both special in their own ways. His is more powerful and flies 80 feet. It loads in over 30 seconds. Mine is a little less powerful but flies almost 150 feet. Mine loads in under 15 seconds. Also, Mine uses 8 rubber bands and his uses 16. Here is the puncturing using the same front on the ammo. Try to build them before you decide. WHOSE IS BETTER. Note-I did not fake these pictures. Try them yourself and the results will be the same. I am not trying to start a fight I just want to see whose you think is better. Note. The Video was shot with IAC's V5 and my V2.3. I just built V3.0 but did not post it yet.

We have been using potato cannons in a BSA camporee and someone just told us that these cannons are illegal. When they are used they are in a safe place, like a rifle range. The cannons are mounted so they can only go up and down and not side to side. If you know of a Michigan state document I can use to show the legality, please let me know.

I have planned to build a vortex cannon for shooting smoke rings. My questions are now: 1. Is it essential to have a round container? Or is a square card box as good? (there are no square smoke rings, or :-) 2. If it is round, does a short and big (in diameter), or a slim and long one better? 3. Using drinking straws on the exit, would this have an effect (in the style of laminar flow)? Thanks for your thoughts,

Is it possible to make a strong magnetic cannon using camera flash units? I've read about some instructables that provide instructions on using several capacitors connected in parallel to provide higher current, but I'm really skeptical about the performance of such a cannon. Can anyone make an instructable and provide video evidence on this??

Hey, I need help from people who have built or bought potato cannons. my capstone high school senior engineering project is centered around building a better potato cannon, and part of the project is doing some market research. I've got a quick (10 question) survey that's built to just get an idea of problems with current potato cannons, the kind of demographic that generally uses them, etc. Please help with this project. I'll probably post instructions on making it here when we're done. here's the link to the survey. http://www.surveymonkey.com/s/PTNSBJW thanks if you can help.

Ok, so I'm planning to make this instructable, it shoots out batteries at incredible velocities. It's fairly dangerous. It involves the use of match powder. However, it has come to my concern that people might worry or even hate me for posting this instructable. So I'm going to ask users on this instuctable if yes or no, they want me to post it. Here's a picture of the damage it can make. The first picture shows the side where the battery first stuck into the 3/4 inch thick wood, the second shows the other side where the battery left. So, do you want me to post it?

Hey everybody, I'm searching for free plans to build a cannon. Why? because I've seen the video of the mini cannon and I want to make one to. The size of the plans doesn't matter(as long as the proportions are right of course), cause I probably gonna resize them any way. I do prefer if the measurements are in meters and not in inches. Futhermore I would appreciate guides and tutorials about cannons and how they work. Preferable cannons of napoleons time.

So After toying with the Idea of making a large and powerful cannon without making a piston valve I do believe I have an answer to the problems associated with using ball valve (bad for power) and piston ported valves (too much effort) I think I've found a simple way of making this work, only question is, with gas power and pneumatics galore do we need another? It would be in the same sort of category as the behemoth but a simpler build, what does everyone think?

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.

I just watched a Mythbusters where they made a pneumatic soda can gun. Go to 5:50 in this video to see their description of it. Go to 7:00 to see it in action. http://www.youtube.com/watch?v=ZMYuQ5daXxk&feature;=related My questions are: what is the "fast acting valve" he used? How do you refill that thing? Anyone seen an instructable for something similar? I've seen lots of PVC versions, but I like the metal version because it's sexier looking, and potentially higher pressure/power. Thanks!

Question by generaljuan | last reply
I've opted to go for the modded sprinkler valve trigger. My questions are thus: Where can I find the required 'blow gun'? What is the 'blow gun' for when not killing potatoes? Will the valve reseal if the trigger is released before all the pressure in the tank is gone? So, can you fire more than once before pumping up again?
Question by AdmiralNiik | last reply
I don't know how much more random fun you can find. I discovered this while at a buffet with my girlfriend and her brother on his birthday. Anyway, I was finished after two plates and a salad, and was balling the straw wrapper between my fingers. A tiny piece, probably a half-inch by a half-inch, ripped off in my hands. Staring at this little fragment, I put down the rest of the wrapper. I balled up the fragment, and put it between my fingers in such a manner that when I blew, it sent the fragment flying at great velocity. Thank God no one noticed or was killed. I have yet to chronograph this little amazing scientific breakthrough, but I estimate about 25 fps. Cool, huh? Anyway, rip off a tiny corner of a napkin or straw wrapper. Ball it up. Touch your thumb and index fingers on both hands together like you're rubbing something off of them. Put the tips of them together, and there should be a little diamond-ish hole between the four fingers. That's where the ball of paper goes. Put the ball in that hole, and pinch gently. Put your lips up to the hole, and blow. If nothing comes out, good! Blow to ready this little weapon, and release the pinch of your fingers to fire. Awesome, huh?
