How to Make a Marshmallow Gun or Marshmallow Shooter

This marshmallow gun (marshmallow shooter) will completely surprise you with its accuracy, range, and ease of construction. Plus, it's tons of fun and a lot better than any store-bought toy because it encourages modifications.

Marshmallow shooter kits with all PVC pieces pre-cut are available in the Instructables store!

This project appears in print as part of Best of Instructables Volume 1.

Instructions are here for the Soda Bottle Safety Goggles.

Step 1: Plans

Get the plans for the gun here or click on the "i" in upper left of the image to get a larger size.

(22 inches of 1/2 PVC pipe (1/2 is a the nominal diameter, its actual outer diameter is closer to 7/8 inch), 2 end caps, 2 three way junctions, and 2 elbows.)

Here's a pic of my marshmallow shooter, it is compressed air powered. I think this is the simplest design you can make, for an air powered gun that is. I decided not to make an instructable on it, because there are lots of other instructables on air powered guns. And also, this design is self explanatory.

I've been trying to find a good tut on something like yours! All I could find were oversized "potato guns". Could you either post an Instructable on how to, or PM how? I think I have most of it figured out, but could you let me know what the small, black thing is on the bottom? I take that is how you fill the bottle with air. Thanks in advance! Btw, how far does this thing shoot? It's awesome.

I made mine a little different. It shoots a little too far for indoor fun.

This is so fun, I just finished cutting up enough PVC for 10 'guns' for my daughters 11 th bay party. I plan to send the kids through our small park retrieving parts from strategically placed brown paper bags with clues & directions, and then making them work together to put together & assemble. I found food coloring spray to color the marshmallows for fun ( lavender & orange) and at the end when they are built, they can have a "war"! Then onto to cake & ice cream! I will let you know how it goes making the pieces found in a hunt... I think it will keep them busier the just building them .

Hi juliblue :0) I was thinking about how much fun it would be for kids to do a "make and take" party -ahh yes 'tis true, great minds think alike.Your party sounds totally awesome! Please leave enough lead time for my invite to arrive because Snail Mail is especially slow in Canada. I assume casual attire is the way to go. Yes? ;0)

I love these Instructables! The first mini-marshmallow guns I made were an adaptation from one I read here and my youngest grandson and I have had a ball with them from the time he was a pre-schooler (he'll be eight in a couple of days). Because my husband is a veritable Renaissance Man, his toolboxes include a pipe cutter. They're not very expensive and they make very quick, easy cuts on PVC pipe. Great job on this 'ible, with neat pictures (and I don't mind the "lies"!).

I know I'm late to the party but I had to say thank you for the simple and clear plans! I know five adults and four kids who are going to have a super marshmallow war on the 4th!

This is awesome. I love how you used PVC pipe for this 'Ible. The safety goggles are awesome!

You should put how easy or hard a instructable is so u kno how hard it is

Brass bum8 years ago

do you reckon you could integrate a CO2 canister firing mechanism?

rrrmanion Brass bum4 years ago

depends on the pressure of it, it migt be too igh for this plastic piping, but aluminium piping may be able to handle it

skelly7447 rrrmanion4 years ago

not at all, this stuff can take over 100 psi if glued properly. the main possible point for failure is the joints

just so you know the marshmellows where i live dont fit into a 1/2 pipe...so i have a whole bunch of pipe cut and cant use it ....i have been drying the marshmellows for 2 weeks now and they still dont fit..but that kind of defeats the purpose of the marshmellows being soft and not hurting anything...might have to take a marshmellow to the hardware store with me

androuman tracyo4 years ago

Exact same happened to me, i wasn't shure if it was the brand of marshmallows i bought, but it was easily enough solved by putting the marshmallow between my palms and rolling it into a "ball". roll for about 10-15 seconds and the marshmallow will fit perfectly into the tube

ilpug4 years ago

for a test of principle, just get a normal unmodified peice of 1/2 inch pvc and shoot them out of that. probably work better than any fancy gun.

ilpug4 years ago

theres a dude in my town who sells a slightly different version of these. his can shoot someone in the face accrately at about 80 feet. he takes them to thrash metal concerts and shoots it into the mosh pits.

mrschneeebly ilpug4 years ago

What is different on those that he sells than the one here? It would be sweet to shoot a marshmellow 80 feet.

ilpug mrschneeebly4 years ago

his guns are in-line without the elbow on top, they are just a straight pipe, with handles, they might have a litttle bend in them, he makes both kinds.

mrschneeebly ilpug4 years ago

Oh ok thanks, I'm going to try that design out.

acer738 years ago

are the safety glasses nessesary

kelseymh acer736 years ago

Yes. Marshmallows or no, weapons-fire training should always include the use of safety equipment. If for no other reason, it trains the habit for when it really does matter.

Remember, "It's only fun until somebody loses an eye."
