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

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.

Luis G Asuncion from City of San Jose Del Monte, Bulacan, Philippines on November 16, 2019:

Cool. Takes time to finish this kind of project. Thanks for sharing.

Ginger M Duncklee on February 05, 2017:

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 on May 29, 2016:

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 on March 28, 2016:

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 on January 22, 2016:

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.

Michael on January 21, 2015:

What was the diameter of the base?

Emily Tack from USA on October 18, 2014:

Great idea! We have built igloos, but not one like this! I am going to share this with my daughter, as her 9-year old daughter's class would really love making one of these igloos.

Yvonne on October 08, 2014:

Can use as a green house.

Chuck on October 04, 2014:

this is a great idea would be really great if you would use spay foam on the inside and out to make it last.

Celticep from North Wales, UK on September 23, 2014:

Fab idea! My grandsons would love this!

tammy carlson on September 22, 2014:

it's a very great idea, and a very good environmental project on what you can do to help the planet. and to reuse plastic. Wonderful job.

OUTFOXprevention1 on March 17, 2014:

That igloo is so cool!

MzLizzie on January 17, 2014:

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?

The_Kelster on January 11, 2014:

This is so incredibly awesome! My aunt works with pre-school and kindergarten children and this would be so fun for them, I am going to forward this to her :) thanks!

Great Lens!!

Ben Reed from Redcar on March 20, 2013:

A thoroughly enjoyable visit - thank you.

anonymous on February 27, 2013:

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. :-)

Margot_C on February 24, 2013:

How clever! It teaches lessons on so many levels. It's a great way to recycle and I'm sure gives the kids a big sense of accomplishment. Thanks for sharing.

rattie lm on January 23, 2013:

I just LOVE this. Can't imagine how it fitted into the classroom but what a great experience, reading, writing, creating, discussion, give and take, all factored into the making of this. Just fabulous!

@CornellMarCom LM: Our Cub Scout group is working on a part of the Black Star

CornellMarCom LM on January 12, 2013:

What a great idea. This would be good for cub scouts.

johnsonwarren (author) on January 10, 2013:

@anonymous: I don't see why one couldn't build an igloo entirely out of half gallon jugs. It would take a lot of them.

anonymous on January 09, 2013:

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!!

anonymous on January 05, 2013:

Cool. Project. Thanks for posting. I'm sorry your 80 glue sticks cost $12! You need to order form Dickblick.com. Get them by the lb or 5lb, they are cheaper than anywhere on the net. Happy building.

scribenet lm on December 31, 2012:

I bet the children just love their igloos! Great idea!

anonymous on December 30, 2012:

A great lens! Great ideas!!!

anonymous on December 27, 2012:

I think this would be a great rain shelter for my free range chickens. They don't like the rain. Might make a good dog house too.

anonymous on December 14, 2012:

@anonymous: im guessing it was a fridge box or similar, folded out :)

maryseena on December 11, 2012:

A great idea!

StartYourDaycare on November 21, 2012:

Super cool! I can't wait to implement this in my classroom! What a fun reading area. Thanks so much!

Freestuffer LM on November 19, 2012:

Wow nice.

johnsonwarren (author) on November 19, 2012:

@anonymous: The cardboard came from an appliance box which we obtained from a local big box store.

anonymous on November 19, 2012:

@johnsonwarren: where did you get the giant piece of cardboard to put it on?

anonymous on November 13, 2012:

@anonymous: make sure the milk jugs are super clean and dry...i have made several of these for my classroom, and i leave the lids on to keep the smell away.

anonymous on November 09, 2012:

im going to do one for Christmas and put lights in it and put it outside neat idea thanks

anonymous on November 03, 2012:

Pretty cool!! Good job you guys. Wonder how it will work for a hot house...

anonymous on October 22, 2012:

I just collected over 400 jugs and plan to start building the igloo on Monday for my preschool. The hot glue didn't melt the plastic?

johnsonwarren (author) on September 30, 2012:

@anonymous: The radius was about 50 inches, meaning the diameter of the first cirlce was about 8.3 feet. We used a string and a marker to draw this on the cardboard base.

anonymous on September 29, 2012:

What is the diameter of the first circle laid down?

SecondSally on September 27, 2012:

Very cool if you've got the space.

anonymous on September 26, 2012:

@johnsonwarren: Do you have any ideas that this could be a modular igloo? I want to make one, but need to store it from year, to year. Thanks Wendy K

anonymous on September 22, 2012:

It looks so cool, I can't wait to build one, but I won't be doing it until fall 2013, that's when I will be taking over the school library that will be K-8. I would like to build one that will be permanent, that I would need to store. Does anyone have any ideas of how it could be built maybe as a modular igloo? I also would like to string some clear mini Christmas lights to give it an illuminated glow? Thanks Wendy K

anonymous on September 16, 2012:

@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 (author) on August 21, 2012:

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 on August 21, 2012:

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 on July 23, 2012:

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.

steph-naylor on July 23, 2012:

This is a pretty cool lens!

anonymous on June 19, 2012:

Awesome! Thank you for your information. It helped us out a LOT when we made ours. http://beautyinblissfulness.blogspot.com/2012/06/m...

@jimmyworldstar: velcro dots maybe

fullofshoes on May 27, 2012:

Never seen anything like this before and it's wonderfully creative! ~blessed~

KayeSI on April 09, 2012:

What a fun idea for grandparents and grandchildren as well! And so educational! We've been learning about the Inuits - this could make a fun summer project.

anonymous on April 04, 2012:

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 on March 31, 2012:

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 on February 04, 2012:

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

anonymous on January 13, 2012:

@johnsonwarren: Thanks. I'll post a picture when I am done. Kids are so excited.

johnsonwarren (author) on January 13, 2012:

@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 on January 12, 2012:

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?

anonymous on January 07, 2012:

AMAZING!! I love this idea.

johnsonwarren (author) on January 02, 2012:

Many people ask what happened to the milk jug igloo when we were done. We were able to tear it apart, stomp the jugs flat and haul them to the local recycling center. They filled up a minivan, but we got them there.

anonymous on January 01, 2012:

What did you do with the igloo at the end of the year?

Buchamar on December 13, 2011:

This is absolutely adorable!

luckyone924 on November 15, 2011:

i enjoyed your lens! my niece and nefew will love to make one time to start saving milk jugs!

You have a very resourceful lens.

Jack-in-the-Box on November 09, 2011:

What fun! I love it. Thanks

anonymous on November 08, 2011:

A couple of years ago my kindergarten class built an igloo using 1,000 plastic jugs. We were able to fit the whole class of 24 students and the teacher inside the igloo. I am now building an igloo with my first grade class. They are so excited! This is an activity that I am going to do every year.

yayas on October 28, 2011:

This is an amazing milk jug igloo! I can hardly wait to share this idea with the teachers in our school. Thank you for sharing such an outstanding idea.

kingsrookie lm on October 25, 2011:

Great lens! Really innovative

Lee Hansen from Vermont on September 03, 2011:

I love the concept and the lessons in this milk jug class project to create a reading igloo. Like the cone of silence built from recyclables by group effort. Brilliant!

Stephen Carr from Corona, CA on October 10, 2010:

That incorporates a lot of skills, including math and problem solving! Great idea!

Jeanette from Australia on September 10, 2010:

These igloos look truly amazing! But your milk cartons look bigger than the ones we normally get here in Australia (how do they ever fit in your fridge door??). I guess we'd just need more.

KarenTBTEN on February 07, 2010:

That is a great classroom project -- beneficial to students on so many levels!

Evelyn Saenz from Royalton on February 07, 2010:

Great resources for building a milk jug igloo.
