Mini Cannon

This video by YouTube user 43287633 shows off the abilities of a tiny custom cannon. Check it out to see this thing take on soda cans, glasses, balloons, and more. Unfortunately, there's no other information about this one, but I do love the fact that the firing range is the creator's own desk. That's some serious confidence in the reliability of the cannon. via Neatorama

Candle Cannon

These guys built a huge version of the AirZooka and are able to send blasts of air strong enough to knock out candles at well over 100 feet. I want to make one! via Neatorama

Cupcake Cannon

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

Air cannon

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

Plastic Cannon??

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!

Potato cannon efficiency? Answered

Tennis Ball Cannon

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.

Knex Magnum Cannon?

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.

Spring-loaded cannon

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     ------> ===== <----|

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.

Question regarding vortex cannon

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,

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.
