This project was a fun one. I went through probably close to a thousand cheese balls before it was all said and done. Even so, the local wildlife had them cleaned up no more than a day later.

This is built around an electric leaf blower with a little PVC pipe for the barrel. The leaf blower acts as a high volume air supply that propels the cheese balls, and a little bit of manipulation of the air flow ensures that the cheese balls feed smoothly. I'll get into that part in later steps. The embedded video above demonstrates the full process to make this project and of course written instructions will follow.


  • Lots of Cheese Balls
  • Leaf Blower
  • 1" PVC Pipe
  • 1" PVC T Fittings (x2)
  • 1" PVC Coupling
  • 1" PVC End Plug
  • Epoxy
  • Stiff Wire (Music Wire or Clothes Hanger Wire)
  • 3/8" Nut, Bolt, & Washers

Step 1: Barrel Mount

The first step to this project is to figure out how to connect a 1" PVC barrel to the business end of whatever leaf blower you happen to be using. My blower conveniently came with a detachable piece to allow a leaf bagger to connect with the front end. This made it easy to secure a PVC fitting into the connector with epoxy which then snapped right on to the blower. I used a T fitting so that it would take up more space in the opening and less epoxy would be necessary to fill the gaps. The part of the T that is submerged in the epoxy has an end plug pressed into it to keep epoxy from leaking inside while it cured. I used duct tape to hold the PVC in place and seal off the openings while the Epoxy was poured.

Supposing your blower does not have this same sort of detachable bagger fitting you may have to devise an alternate method to seal a PVC fitting into the opening. Creating an attachment with fiberglass may be a good option, or you could simply tape the fitting into the blower for a temporary solution.

do you know what brand of leaf blower that is

I'm seriously wondering about the excitement of this idea+paintballs+Li leaf blower would produce! By the way has anyone ever said Wil Wheaton looks a bit like you?

Ha! I love this! Pay no mind to the nay-sayers, we've all got to have fun now and then. This is just too much fun. :-) Kudos, sir!

Hey I like it...Your project is amazing

I would fully support this project if I did not love cheese balls so much. Seeing the death of hundreds of cheese balls is painful to watch. But perhaps this project can be modified to accommodate a large group of people at the other end who can try to catch them in their mouths.

Are they cheese puffs, or balls of actual cheese?

Very cool project. Could you use a SANITARY TEE or WYE PVC fitting instead of making that little wedge part or don't you think it would create enough vacuum? You might need a reducer, because I think they come in 1.5" for the smallest size. What about using a cordless blower to make it more portable? I think I would also put a cheap light weight gear down motor to turn that crank instead of using your hand. I'm just thinking for kids, they might need both hands to hold the thing and then how would they turn the crank? Again, VERY cool project and one I'm going to build next weekend. Keep up the great work.

You can try a sanitary tee, it might work. Let me know how it goes!

Awesome, I don't think we have cheeseballs where I live, but I can probably find other eatable ammuniton :).

I don't like projects where you waste food. Even if the wildlife enjoyed it.

I'm sorry, if those are considered food, then you better check your diet. I think this has to be a better use for them than eating them.

Hahahahahaha! TRUTH!

Amen to that!

yeah this machine gun helps people to throw away their fat potential. one of the best instructables. next you should invent a hamburger machine gun oiled with bacon crispy. ;)

can i use this with paint balls???

NightHawkInLight (author)  dragonfrog663 years ago

Paintballs are probably too heavy to go very far.

Very cool, right up there with the potato bazooka. One question, what do think of doing this with a gas powered blower? Would it work or is a gas blower too much.

well, If you got some other kind or motor, and made the hole juuuuust big enough for the paintballs...

this may just be my favourite Instructable ever? ?

Dunno. Using cheese puffs as ammo might class it as a weapon (at least on the West Coast where cheese puffs "are known to the State of California to contain ....")

Even worse you risk exposing people who claim to have a dairy allergy because it's inexplicably fashionable by shooting them! Also people who claim their children have a dairy allergy which explains their behaviour because it's easier than actually parenting and them. ?

(Yes I do know a very small number of people genuinely have an allergy to dairy products and are unfortunately prejudiced by association with middle class idiots who want to seem more interesting than they are.)

Great production. I very much enjoyed it.

Neat idea - cheese balls that come in a bag don't qualify as food.

PeteP113 years ago

You Sir, are a hero.

Your next video needs to be blasting these things into someone's open mouth. Ha ha, neat idea.

Bring a battery-powered unit to the shore with a seagull population and watch the show...

So cool, but I don't think my mom or dad would like me making this, but I will try.

waraji3 years ago

It looks like fun, but are you absolutely sure all that cheese is beneficial to the wildlife? Ask a local wildlife biologist.

I can see using a battery powered blower and taking this into school. My students would love it. Admin? Not so much.

Simply genius !!!!

i like this concept dude

Hard does it hit? I'm tempted to just stand in front with a gaping mouth(and some eye protection). Very cool build!
