Step 2: What Is a Candy Cannon?

This is the Candy Cannon!

It uses an electrically activated in-line sprinkler valve, rated at 150 PSI, as the trigger mechanism to release compressed air through the barrel.  

Just charge the system up to around 150PSI, and press the detonator button to make it fire!

I built this one for my son's 3rd birthday party to propel a payload of candy to an altitude of around 100 feet, at which point the candy begins to spread out into a giant could of sugary treats, and drop back down, making it rain candy!  

You can probably imagine the excitement of the kids with their little treat bags running all around the yard on a candy treasure hunt!

This is awesome, But, it made me really hungry with the title. I'm gonna get a cookie now.

Great project! Do you have to use special high-pressure pipe, or just regular?

how do u make the barrel adjustable

Awesome Idea, This is an amazing build.
Hey, thanks!
Big fan Mr, KOR,
I am a novice at best doing these projects and have never been a handy man around the house. with that said i have mo knowledge of the materials that you used to make this project. i know it may be a hassle but do you have a full list so that i do not get the wrong stuff and blow my hand off in an attempt to improvise?.lol

I've made an air cannon similar to this before. Good stuff! My question is reload time is slow from the time spent with the air compressor. Do you know of a way to hook up a CO2 canister to make it portable and somewhat quicker for reloading. Thanks.

I love this project but like many of you I work better with a parts list, has anyone been able to get one ? thanks and keep up the great work..:)

I would love to build this for my daughters 6th birthday this weekend. Would it be possible to get a more detailed list of supplies? She would really love this. My email address is zamora123@earthlink.net if it's possible.

Chocolate rain.... some stay dry and others feel the pain.
Do you happen to remember the total price on this project?

Great cannon. I've built a few myself using a very similar design. I use the same type of valve but I've had mixed results with only using 9V. Sometimes 9V work, sometimes I need to use 3x9V. It seems to me (and I may have missed something) that my valve needs more voltage as the pressure increases.

I love the nice finish you put on it too!
Thank you so much. That was the only part I couldn't find.
I know you didn't do it in this video, but in the ak 47 video you made a bike pump adapter and I was just wondering where you got it?
P.S.
you make the coolest things ever. I love the solar scorcher and both air cannons
Thanks!

I made the pump adaptor from a valve stem. You can get these at auto parts stores or companies that deal in tire repair.

All the best!

I gotta say, your ingenuity with common materials and simple tools is amazing! The nice flourish like a paint job you have for every project really finishes it off. Thanks for another great project idea!
The King of Random (author)  Mig Welder1 year ago
Thanks for your nice compliment Mig! I have a project on making a stick welder from microwave parts coming up soon. I'd love your feedback on it since I have no real experience welding.
No problem! I look forward to giving you some feedback! In fact, I've made a few MOT welders in my time but I look forward to seeing your take on it. Keep the guides coming!
Always the life of the party! Are these pics at the park or your yard? What a fun 3rd birthday! :)
Only second to you Natalie! This is our back yard .. but the park wouldn't be a bad idea. The spray radius of the candy is amazing!
We need to be neighbors again! We are planning a My little pony party for Hailee...and pinkie pie has a party cannon. This would be perfect! :)
@doodlecraft - I don't mean to break in on a private conversation but it'd have to be a REALLY big cannon to launch a pony - pink or otherwise. :)

@TKoR - Well done (scurrying off to the basement).
:) Are you off to make the Pony Cannon? lol
Nah, my wife won't even let me make a pneumatic punkin chunker. No WAY she'd entertain a pony cannon. Besides, the SPCA and all that . . . Nope, I'll stick to inanimate objects, thanks. :)
I agree, we should .. only we're sick of moving .. so are you interested in coming back???

So I've done allot of work with potato cannons and I've found a great way to launch grape shot or in your case candy is to create a re-usable "seal plate" rather than needing to cut up the cups. This is done by :
1. cut a one inch long section of scrap pipe (same pipe as barrel)
2. buy a tube of GE Silicone 2 Caulking
3. Lay the pipe "ring" down on a smooth flat surface
4. Fill the ring with the caulking, allow it to cure.
upon curing you will now have a perfectly sized plug for your barrel, The friction between the plug and barrel walls will create Fk which can decreasethe projectiles velocity although I find it preferable to deal with this Fk because it seems to be less of an issue than the lost air pressure due to using other "plug" type items. - Hope this helps!
- Side note: You can also cast awesome projectiles using silicone that are reusable rather than wasting a bag of potatoes. Although these cast silicone projectiles bounce, so be careful of ricochet.
The King of Random (author)  seltzer101 year ago
Great feedback and comment. Thanks! Just curious, what silicone are you using for casting? Is it a 2 part mix, or something you could pick up from home depot?
Thank you! I used " GE Silicone 2 Caulking" It is a white tube with a GE logo labeled as such, it comes in caulking tubes and can be mixed with corn starch if you're looking to give the projectile a more ridged form. Check out this link to another ible that uses casting of the same sort with a similar form. This cornstarch/silicone mixture is hardly my invention I've simply found a projectile use for it. this mixture is commonly referred to as "oogoo" http://www.instructables.com/id/SiliconeOogoo-Brain-Slug-from-Futurama/step3/The-Oogoo/

-note: Increasing the amount of corn starch used will decrease curing times and using the GE 2 silicone will reak of what smells like acetone/vinegar so do it on your porch of outside if ya can. Its not really an issue its just not an atmosphere I enjoyed breathing in my small basement shop the first time I did this!
I wish you were my neighbor instead of the busy-body one that I have now. I used to live on 5 acres of land, but have been reduced to a subdivision due to job change. No matter though, I am having my own shed delivered to my backyard in 2 weeks, and I'll have 12'x16' of man-cave ready workshop :D
Nice :D

Good god. You let your kids eat unwrapped candy that was not only in piping smeared with industrial adhesive, but that was on the lawn crawling with bugs and bacteria?
The King of Random (author)  qczx9991 year ago
This sounds like a loaded comment.

I don't believe at any point I impressed that they ate this candy. If you read the instructable, the unwrapped candies were for testing the ballistics, but individually wrapped candies were used for the parties.

Now saying that, what exactly is the purpose of your comment?

Did you know that your water pipes are smeared with the same industrial adhesive you sound so concerned about?

And the fertilizer for your food is made from cow manure as well as the same lawn crawling bugs and bacteria?

Even if we did eat unwrapped candies from off the lawn, I personally am not concerned about it. I'd eat them too. If it's a big concern for you, then I suggest you do something you're more comfortable with.
Mr Random, you sir, win the Internets today. This was the kindest response that could possibly have been made to the above comment. In honor of your restraint, I too shall refrain from name calling.

Excellent project, I have made one similar and have launched cardboard tubes for plotter paper well into the sky. I hadn't thought of using it to shotgun candy. I make the kids use a bicycle pump to air it up rather than my compressor, they are usually too interested in getting to the next launch than they are in getting the pressure up higher than I am comfortable with in the PVC.

The cardboard tubes make a marvelous "thwump" sound at launch.

Glen

PS- If I had an extra one, I'd give you TWO internets.
The King of Random (author)  Lazy Glen1 year ago
Hey Glen! Thanks for sharing your experiences, ideas and compliments! I'm too lazy to pump it by hand, but when my kids get older, I'll be sure to throw the bike pump adaptor on it. Those kids need a place to vent their energy and that's a great way to do it!

Thanks again! :D
