How to Build a Milk Jug Igloo

Igloos are cool. You can easily build an milk jug igloo in your classroom with some planning, lots of milk jugs, and hot glue.

For example, children at Midland Christian School in Midland, Michigan built the 428-jug igloo (shown above) after collecting and cleaning milk cartons for about three weeks. This medium-sized igloo is large enough to hold about 8 to 10 kindergardeners or first graders during free reading time—and a principal fits in there too!

  • Total cost: about $12 for 80 glue sticks. The milk jug igloo provides all sorts of opportunities for links to social studies, math, science and reading topics (many of which are listed below).
  • A milk jug igloo is a great project for a classroom, nature center, library, Vacation Bible School, children's museum, daycare center, recycling center, or dozens of other places that seek to inspire children.

Watch the following video to get a nice overview of the process. Then check out the sections below for resources to add to your unit on snow, seasons, winter, recycling, or other topics.

How to Build a Milk Jug Igloo in Your Classroom

What You'll Need:

• LOTS of clean recycled plastic milk jugs, mostly gallon-sized but a few half-gallon jugs will be helpful too.

• A cardboard base. This can be made of several big pieces of cardboard taped together.

• High heat glue guns and glue sticks.

Steps to Making Your Igloo

Watch the above video for details!
1. Collect clean plastic milk jugs.
2. Tape together large pieces of cardboard to make a base.
3. Using a nail, string, and a sharpie make a circle on the base as big as your igloo will be.
4. Begin gluing jugs together with handles together. Then glue sets together with back tops touching.
5. Create the outer row with sets of four jugs. Make sure to leave an opening four jugs wide.
6. Add four more rows. Your sixth row will include jugs over the door opening.
7. Move each row in slightly to create a curvature.
8. When you reach the top, use half-gallon jugs to fill the hole.
9. Create an entry way. If you face jugs out you can decorate with colorful tops.

Some Practical Tips and Lessons We Learned

We learned some things from our igloo project. If you build one in your classroom (or home!), making priorities of these steps will make the project much easier.

  1. Promote Jug Collection Our milk jug igloo took more than 400 milk jugs. That's a lot of milk! (Or orange juice, or water). We put up posters around our school signed by the children and inserted a notice in the school's print and e-newsletters to get the entire school of 100 studeto help the collection effort. In addition, our teenagers "liberated" milk jugs from recycling bins in various areas of the city on recycling days. A parent helped out by collecting jugs daily from a local coffee shop. It took us three weeks to get all the jugs we needed.
  2. Wash Jugs Well You'll want to wash the jugs well as they arrive. Otherwise your classroom will begin to smell pretty bad and you'll be teaching a lesson on microbiology instead of snow. We strung the jugs in groups of 10 and stored them in a corner of the room.
  3. Use a Cardboard Base Using a cardboard base will give your igloo stability as you glue the first row down. You can get a large box from your local big box or appliance store on delivery day. A refrigerator box works well.
  4. Use High Temperature Hot Glue The Inuit call these structures "iglu," which is appropriate because you'll use lots of hot "glu." We used about 80 long sticks, which cost about $12. A new dual-temperature gun was about $14 on sale, so our total igloo investment was under $25. Because of the dangers of getting burned, the children played a limited role in the actual construction, but there was still plenty for them to do with counting, graphing, making patterns out of the lids, and washing.
  5. Collect Extra Caps Most milk jugs we collected didn't come with their lids. You may want to start early collecting caps so that you have enough to make patterns and decorate the final result.
  6. It Takes Time We built a few rows a day, mostly after school and on weekends. It took about 12 hours to make our igloo, which easily holds 8-10 first graders.

Building an Igloo Is an Opportunity to Learn

• Snow, winter, seasons, geography, and cultures.

• Math and science (counting, sorting, estimating).

• History (Inuit and other Native cultures that build igloos).

Tips for Planning Lessons

  1. Pre-plan Your Entire Unit Your igloo will be part of "a complete breakfast." In other words, it will complement the unit that you are teaching, whether it's snow, winter, seasons, geography, cultures, or ecology. The more interesting your unit, the more impact you'll have on achieving your learning objectives. There are all sorts of extra resources listed below. Please add additional ideas in the comments section so everyone can benefit from your good ideas.
  2. Emphasize Reading Your completed igloo will be great for a reading nook. Talk about the kinds of books that relate to your unit. There are some great ideas listed below, including picture books that first graders could read themselves.
  3. There's Lots of Opportunity for Math Counting, counting by tens, graphing, estimating, and patterns (with the multi-colored caps). Your class could collect data about which store most families use to buy their milk?

The Perfect Book to Read While Building an Igloo

Mr. Popper's Penguins
Mr. Popper's Penguins

Of course penguins live at the south pole and polar bears and igloos are at the north pole, but what unit on winter would be complete without reading "Mr. Popper's Penguins?" My wife and I read this book to first-graders, and there are all sorts of helpful tools to integrate this book into your lesson plans and even a CD for an audio reading station.


Nanook of the North: A Documentary About Inuit Eskimos

One of the earliest film documentaries was Nanook of the North, made in 1922 by Robert Flaherty. The silent film documented the life of the traditional Inuit in Canada, showing ice fishing, hunting walrus and seal, trapping, building an igloo and trading pelts at a trading post. A short clip of the movie is available on YouTube.

Nanook of the North (The Criterion Collection)
Nanook of the North (The Criterion Collection)

Our hero Nanook builds an igloo in this film, runs a dog sled, paddles a kayak, hunts for seal and walrus. A bit mildly risque at one point.

I am trying to do this for a cub scout event and am trying to block space. Can anyone tell me about the diameter I need?

Kay Tucker 8 months ago

I live in Arizona and plan on putting together an igloo. I am afraid it will be too hot for the hot glue to hold. I need any suggestions on what else to use to glue them together.

Tigerlily 10 months ago

Also i didnt need a cardboard base or an base. Just the string.

Brought it home from park successfully. No damage from kids or car.

It is now on my verandah

Tiger Williams 13 months ago

This would be a great shelter for animals. Substitute scrap pieces of rolled linoleum, sealing the seams as best as possible, then layer the floor with straw, wood chips and shredded paper (this should be cleaned out periodically). Fill the bottom row of jugs with sand, to add weight and stability. Covering the entire igloo with a cheap tarp helps keep out the elements and keeps in the warmth.

Has anyone tried using tacky glue SPRAY instead of a hot glue gun? I believe it would save time and eliminate the need to hold the jugs together for a minute each time you glue. Any thoughts?

I love this idea. I teach kindergarten in Alaska, and would love to give this a try. One point of clarification, though, for all those wishing to incorporate this into a thematic study. The Inuit live (and have alwasys lived) in the arctic, while penguins are in the southern hemisphere. That's the other cold side of the globe. If you are connecting them based on ecosystem or air temperature, I can see the link, but please don't misinform children to think that Alaska is full of igloos, sled dogs, and penguins. :-)

Would this work with ENTIRELY half gallon jugs? My school goes through about 100 half gallon jugs every week and would be easier to use those as opposed to gallon jugs?? Any insight would be helpful!!

I also would like to string some clear mini Christmas lights to give it an illuminated glow? Thanks Wendy K

@anonymous: The plastic used in these jugs are not UV stable and will begin to breakdown when outside. They will become very brittle and with crumble within a few months.

johnsonwarren 4 years ago Author

Jayne (Aug 21, 2012): We found that it helped stablize the igloo to attach the bottom to a large sheet of cardboard. If you weigh the lower level so they don't move as you describe, that might serve the same function.

anonymous 4 years ago

LOVE this idea! Do you think it would be possible to do outdoors without it all blowing away/being trashed by the weather? Do you think weighting the lower layer(s) with sand/water would be enough to anchor it??

anonymous 4 years ago

Our class satrted to build an igloo outside, but the rain and windswept it away. We are now going to make one indoors. We have to use 2L bottles because they don't sell milk in gallons in South Africa.

I am wondering if anyone has used the small plastic jugs that come with Kool-Aid type drinks in them. It would make an igloo small enough to use for dolls maybe, in a place too small to use the full-size milk jugs.

anonymous 4 years ago

My church did this on a Christmas float. We used them also on bottom of float. We put clear Christmas lights inside of jugs. It looked just like ice. Our theme was Happy Feet. We won 1st place in church division and the Grand Marshall division. Some people come out of the parade and asked what it was made out of. We also had a fishing pond out of jugs also. Santa was going into igloo, all you saw was his rear.

jimmyworldstar 5 years ago

I can't figure out how you could make them stack without falling without using glue. I wonder if that's even possible?

@anonymous: There was a natural curvature to the milk jugs when they were placed with the mouth to the inside of the igloo. We may have moved in slightly as we got to the middle and higher rows, but to be honest, it just seemed to work out.

anonymous 5 years ago

I am in the process of creating this igloo which I think is fantastic. Did you move the jugs in about an inch when you placed each row or did they just fall that way?

AMAZING!! I love this idea.

    I made a milk jug igloo for my granddaughters birthday party. It was a hit with all the kids.

    I didnt use glue. It wasnt strong enough for me. I needed to transport the igloo to the local park and it needed to cope with excited kids at a birthday party.

    I punched holes in the plastic with a metal skewer and then I threaded the bottles onto strong string. The holes are simple to punch and they do not tear. I needed an extra long needle, 15cm, as used to make teddy bears.

    I used hot glue to seal the knots.

    I was surprised by the bottle tops, many will only fit their own brand and i had quite a mixture of brands. (Friends and neighbors helped me collect 250 bottles) the structure didnt need them and i could have left them off but they looked so pretty

    For the entrance, i cut the top off the bottles to make 'sleeves' and slipped 4 sleeves onto the end of every bottle near the entrance.
