Confetti cannons are a lot of fun. An explosion of confetti can make any celebration better. But it isn't always convenient to have someone next to the cannon to set it off. So today I am going to show you how to make a remote controlled confetti cannon that you can set off from anywhere.

Step 1: Watch the Video

Here is a video walkthrough of the project.

<p>This is hilarious. Great job! </p>
<p>You could shoot other things out of it as well!</p>
<p>That's a good cannon! I made one almost exactly like this that shoots Nerf Footballs about 300 yards. There's a few safety considerations for the next one I make. </p><p>Place the air nozzle<br> and gauge where the coupler is. This way, you drill through two <br>thicknesses of PVC instead of one.You can get a better seal and the connection is more solid.</p><p>I am starting to shy away from PVC as an air chamber. I haven't had any problems at 100psi, but if it did rupture, well, PVC doesn't show up on x-ray. It would also be like a grenade! Metal air chamber is preferable. Some people use fire extinguishers.</p><p>I have used the cannon for confetti, apples, footballs, and water. Be careful using water because it WILL recoil and could possibly cause a &quot;hammer effect&quot; and damage your cannon.</p>
I dont recommend ever exceeding the rated pressure. PVC is not that strong.
<p>Wow. My son would love this! :) We had some tubes like that before - we made a potato launcher with my brother. This sounds like a much better option - it would be fun to make for a bday or even the 4th of july!</p>
<p>I'm a bit confused with the valves, batteries, and relay. Your material list looks like you are using 12 volt for the batteries and relay, but the battery pack you show in your video looks like 4 double-a batteries. Isn't that 6 volts? Also, I thought residential sprinkler valves ran on 24 volts. How are you getting the battery pack, even at 12 volts to open the valve? I am sure I missing some basic pieces. I am looking forward to the build!</p>
<p>The battery pack is double sided. There are four batteries on one side and four batteries on the other for a total of 8 (12 volts). </p><p>Yes most sprinkler systems work with 24VAC, but they are pretty versatile because it is just a simple solenoid valve. The sprinkler valve will work with a variety of voltages. Some valves can work as low a 9 volts. </p>
<p>In regards to supplying power to the sprinkler valve, as you say pretty much all the valves I can find locally in Aus for a reasonable price is AC powered. Will they work if I supply DC power?</p>
<p>Most solenoids work with either AC or DC power supplies. They most commonly use AC because AC power adapters are cheaper.</p>
<p>Thanks! I did some digging since placing my comment, and I found this post to be very enlightening:</p><p><a href="http://rayshobby.net/understanding-24vac-sprinkler-valves/" rel="nofollow">http://rayshobby.net/understanding-24vac-sprinkler...</a></p><p>The tl;dr is basically: yes it works, but under DC the coil can heat up much more vs AC (due to reactance) thus possibly reducing the lifespan of the solenoid. But my guess is that since we're only powering the solenoid momentarily (as opposed to holding it open as you would a sprinkler system), it shouldn't be a problem.</p>
<p>Thanks for the information. Would you mind providing the specific model of sprinkler valve? I've been struggling but I suspect it may be the sprinkler valve I purchased.</p>
<p>I don't really know the exact model. It was just whatever generic valve that they had at my local Menards. What problem are you having?</p>
<p>I think I figured out what I was doing wrong. I was testing the valve prior to having it connected with pressure on it. Apparently, you need pressure on the valve in order for it to open.</p>
<p>Yeah that confused me at first too.</p>
I made the basic one without the electric part but the ball valve feels pretty stiff and we haven't gotten a chance to try it yet.
<p>I'm building something similar for military training loosely based off this idea. Because of the higher PSI require to safely simulate an explosion (rather than pyrotechnics) I used a brass electric sprinkler valve. 24 volt. Now, it will work with a motorcycle battery and pressure plate. But (using quatumfire remote cues, 12 volt I believe) It's not enough power on my remote cue to initiate. Any ideas or recommendations?</p>
<p>That kind of igniter has a very limited output. What you need is a remote controlled relay. This will let you activate the valve with whatever battery that you would use with the pressure plate setup. In a lot of my projects, I use remote controlled relays that are designed for Halloween props like these: <a href="http://www.frightprops.com/controllers-electronics/remote-control.html">http://www.frightprops.com/controllers-electronics...</a></p><p>But just about any remote controlled relay can work.</p>
The BIG one :-) Cooooool ! :-)
<p>My own version (Candy Cane selfie stick) in this video:</p><p>https://www.youtube.com/watch?v=RiSv8o1k9BE</p>
Awesome!
<p>Wow!</p>
<p>looks so cool but a bit big for a party in our house</p>
Pretty neat. I made one from some pipes I got at ace. its also pocket sized! I may publish an instructable soon on how to make this.
<p>Nice and Awesome </p>
<p>This is awesome!</p>
<p>This is a really great idea! good job!</p>
<p>Brilliant! Very clear &amp; great idea - thanks for sharing</p>
I built a bait launcher to launch my bait on the shore line while surf fishing with almost the same concept. I have an instructable on here too! Good job! And great instructable!!
<p>Cellular-core PVC (the 4-inch diameter) is not pressure rated, and is not recommended to make the pressure tank. </p><p>Use solid-core Schedule 40 PVC that is rated for applications under pressure (take note of the markings on the pipes in the picture: the 2-inch indicates it's rated to over 200 PSI; the 4-inch says &quot;Cellular Core&quot; and has no pressure rating indications).</p><p>Non-pressure rated pipes are fine for the barrel, as it doesn't contain any compressed gas.</p>
<p>4 inch Schedule 40 is good to about 140 PSI, not counting temperature de-rating. Just because there's no pressure rating printed on it doesn't mean that it doesn't have a pressure rating.</p><p>The builder mentions the doesn't go above 40 PSI. That is more than adequate safety margin. </p><p>I especially like the big ball-valve safety built into the project. Very thoughtful.</p>
<p>I wish Instructables had been around when I built my confetti cannon! Mine looks similar, except I used a heavy oxygen tank for the reservoir. It's capable of holding greater air pressure, but the sprinkler solenoid is much more likely to jam. I like your light weight, more reliable version much better.</p>
This is seriously great. Especially love the pics of the canon in action.
<p>Very nice work Jason. This looks badass . . . as does your expression in the photos in the last step. How did you not blink?!</p>
<p>How about using this to launch candy during a parade? Do you think it could handle a few handfuls?</p>
<p>Kudos friend! Your build is fantastic! Your tips are very informative and your instructable is laid out very well! I've made plenty of Potato canons in my day, but never considered putting a remote on it, much safer firing from a distance. I look forward to building this with my son!</p>
