I'm assuming you don't want an actual ice igloo but something that would resemble an igloo. you could use marshmallows ( the big ones) or white foam cut into chunks. then just glue or piece together using toothpicks
Well you can just go to michaels and by a styrafome hemisphere and a styrafome rectangle shape it dry paint it, and maybe use some cotton balls and put it as some impact snow ... HOPE THIS HELPED ♥ SORRY IF I SPELLED anything wrong I'm olny 11 years old... BYEEEEE
I used washed out gallon milk jugs, donated by parents etc... Then stack them and attach them layer by layer with lots and lots of hot glue, slowly tilting in as you get higher up. I used it as a reading area in my classroom. It will be somewhat fragile, so people need to be very careful around it.
Well I could think of several things like paper mache, plaster of paris, marshmallows, sugar cubes, Lego blocks is all I can think of... en.wikipedia.org
Given below are the instructions on how to build a real igloo. To make a model, all you need to do is replace certain materials like snow, with alternatives or readily available substitutes and simply scale the size down so that it can be used for a project. It is wiser to actually study the design of an actual igloo and construct a model based on it.
Firstly, pack down an area in the shape of a circle as firmly as you can. Then mark out a circle close by and start digging down to make the bottom half as well an entry tunnel. Make use of a hand held saw to cut out brick shaped structures from the packed circle. Position the snow bricks surrounding the circumference of the igloo base.
I suggest you use appropriate materials and try to mimic the above process, although not exactly, but you get my drift.
I did the simplest thing, just typed it in the google search bar, "how to make an igloo" and there it was. Funny, I live in Alaska, and never made one, lol.
Dominos sugar cubes. I use to use them to build roman temples and stuff. Use elmers glue. They're great. You can get jacked while building your project cause they're really good to eat.
