Make a Miniature Marshmallow Gun


Finally…I have a fun project you can make for and with your boys. This blog has leaned a bit toward girls lately, so I am excited to have a fun idea for the other half of the population (although I know plenty of girls who would love these too).


These minature marshmallows guns are so much fun. If your boys are like mine EVERYTHING becomes a gun.

My SIL threw a birthday party for my nephew and they made all the boys their own marshmallow gun. My son loves it!

You place a mini marshmallow into the end of the gun, blow on the other end and shoot the marshmallow at your target. They are amazingly accurate!

It is ALWAYS a good idea to have your kids wear safety goggles when using these guns, because everyone knows that it is only fun until someone gets an eye shot out!

I did a little searching on the internet about making these marshmallow guns and found this great idea for making a pair of safety goggles out of a 2-liter soda pop bottle. I followed these directions but used duct tape to line the sharp edges and make the head strap.

To make the head strap, I simply folded about 20 inches of duct tape in half length-wise and then put another 20 inch peice on the folded peice and folded it in half also. So it was 2 layers thick. Then I just cut it to fit with a little extra on each end of the mask so it can be adjusted for different size heads, after I threaded it through the 2 slits I made on each side of the mask.


You will need:
a 12 inch length of 1/2 inch PVC pipe (sprinkler pipe)
1-1/2 inch end cap
2-1/2 inch elbows
1-1/2 inch T joint


Take your 12 inch length of pipe and with a hacksaw, cut off three peices of pipe that measure 2 inches each and then cut two peices of pipe that measure 3 inches in length.


Take your parts and use the above picture to put them together to make your gun. This is a very simple gun style. If you want a different style, all you would need to do is buy a longer length of PVC pipe and some more joints depending on what shape you are trying to achieve.


I ended up making a gun for my other boy and they spend a lot of time in the backyard having marshmallow wars. They played with them so often that I never had any marshmallows left when I needed them. They buy their own marshmallows now!

So if you have a birthday party coming up, these might be something you would like to make as a party favor, or as a gift for the birthday boy. I was also thinking how much fun these would be at your next family party with Grandma and Grandpa and that pesky brother-in-law!

    I know that my kids (boy – 26 y.o. and girl – 25 y.o.) and nieces (7-14 y.o.)would love to make and play with these too. I can see us doing this at the next family party. Thanks for the directions and pictures.

  9. 9

    Thank you so much for that idea!!!! I am in charge of the crafts for my family reunion this Sunday and I totally couldn't think of anything for the boys (10, 11, 12, 14 and 19). I think this is something that I should probably get enough supplies so that the dads can do them too! This will be the highlight of the party I am sure:).

  10. 10

    This sounds like something I can make with the kids I babysit. But, your pictures aren't showing up =/

    Amy, how much did it cost for the pvc pipe and what was the original length you needed to purchase? Too cute I thought about making these for my boys last year, but ended up finding a pretty cheap blower online so I stocked up for friend presents. I would like it though as an activity for a b-day party activity that then becomes their favor.

  15. 15

    These ended up costing about $1.50 each! Possibly cheaper if you buy longer lengths of PVC and cut it yourself or have the store cut it.

    we bought all of the parts for 12 kids and it cost about $16.00 ! perfect for boys birthday party and favors.

    Just made 5 of these in about 20 min. Super easy. The shortest the PVC pipe came was 5 feet, so I decided why not make 5. We have plenty of friends that will love to play with them. My 2 year old figured it out pretty quick and is so excited to show his cousin!

    We tried these on a large scale – we used them for our "Wild West" Vacation Bible School – cut enough for 170 children and they were the HIT of the year. All ages (including our 30 year old Director) were so excited about these and they were easy but interesting to make. We painted them and girls and boys alike loved them. Bravo!!

    @Anon–Yay! I love hearing that! Thanks so much for sharing. I am so happy that they were such a big hit for you and everyone!

    what kind of games do you suggest for a bday party with the shooters?

  21. 21

    There will be 4 eight yr old boys at the party and I know they will love the guns, but I need something constructive to do with them.

  22. 22

    How and where do you load the marshmallows?

  23. 23

    Just wondering, did you cover the little…hole, I guess, inside the T joint? Because my marshmallows keep dropping inside the hole!

  24. 24

    Love this nifty shooter! Thank you for making the shopping list and directions so clear. I too am making 5 shooters at a time..cost about $6.50. The best parts, PVC made in the USA and my little people can help assemble them!!! Will be following your blogspot for more nifty ideas!

    Another idea for the goggles is, that we use the safety glasses that we get for lowes build and grow.

  26. 26

    Was thinking another good way to make the goggles would be to use the elastic headbands the girls are wearing now. They type that go around the whole head, you could tape that to the top edge of the plastic, that way the part around the child or adults head would stretch and fit just about anyone.

  27. 27

    what if you dont have pipes what do you use then?

  28. 28

    What glue do I use?? I am so in love with this! Using it for a Super Saturday project at our church’s annual craft fair.

      You actually don’t need to use glue. They hold together fine without it. That way you can rearrange them into different gun shapes if needed.

    We are havin problems with the marshmellow shooting very far. I too am wondeing if you covered the hole to the T piece. WE love it though.

  30. 32

    I like this idea! Give kids the fun of “guns” without the danger!

  31. 33

    This is great! I have a suggestion that would be easier to cut it with than the hacksaw. Just use a pipe cutter, nice straight cut and no effort at all. I am so going to the hardware store tomorrow to make these for my three kids, two of which are girls!

  32. 34

    Such a fun idea :)

      Thanks Cristina! It is still one of our most popular summer activities…even the adults get involved in playing with them! Thanks for stopping by and sharing a comment!

    Hi! I could have sworn I’ve visited this website before but after looking at many of the posts I realized it’s new to me.
    Anyways, I’m certainly happy I found it and
    I’ll be book-marking it and checking back regularly!

    Thankyou so much for this great tutorial! I think this will be the perfect thing for his birthday party coming up. Only question is, do you think 3-4 year olds would be able to successfully operate this? How hard is it to “shoot” the marshmallows and do they go very far with little effort?

    • 38

      They can go pretty far. The only thing I would worry about with the younger kids is accidently sucking instead of blowing and then possibly ending up with the marshmallow in their mouth (possible choking hazard). I have only used it with older kids (5 and up). You could put a piece of netting on the inside between the mouth piece and where you put the marshmallow in by trapping the net in between one of the pipes and then snap them together over it to secure it in place. This would prevent the marshmallow from entering the mouth accidently. Then I would think it would be just fine for the younger kids.

    I am using this as one of my hubby’s father’s day gifts. I am going to send him out on a treasure hunt with clues where he can find the next clue. Each clue will have a piece that when all gathered, will make the gun. Then we will all have a marshmallow war. My clues will be personal to my daughter like, “the place I was born” and “the first place you and mommy met” ….things like that. Oh this is going to be so much fun! Thanks for sharing.
