This is not really an instructable. It is more of what I did to create this costume and hopefully you can use some of the ideas from it. I didn't take as many pictures as could have been so you might have a few questions.
This costume was made for a Halloween contest (unfortunately the contest was canceled at the last minute due to poor ticket sales). The only way I could get to the contest was by city bus so I phoned the bus company and found out the dimensions of their doors. This costume stands about 7 feet high, 3 feet wide at the shoulders, and is about 2.5 feet front to back.
Oh, and there are no pictures of me in the finished costume. I couldn't get it in my door to take pictures in the mirror!
Here is the material list:
For the paper mache; (Did I mention the costume is made out of cardboard and paper mache?)
-old pair of pants
-red plastic from a plastic file folder
-strips of rubber for feet
-pieces of wood
-cloth for padding
Camo, words, and symbols;
-red latex paint
-black spray paint
-white spray paint
-yellow craft paint
-white craft paint
-red craft paint
-green craft paint
-plastic flower pots
-lights that clip on to a hat
-2 6v gel cells
-large sewing needle
-heat gun (to speed up the drying process for the paper mache)
There are miscellaneous items like screws and stuff. The back bottles are from a water cooler I found.
I'm not going to describe how I made the smoke bombs for the smoke generator nor the ignitors for them. Also the gun on the left (left side of the picture) fired special confetti shells I created. They sounded like a shotgun going off and spewed confetti everywhere! But I made sure that it was absolutely safe by doing extensive testing with the shells and gun before putting it anywhere near my body. So I'm sorry but I can't tell you how I did that. It is very dangerous if you don't do it right.
As for the price, I think this costume cost me about $50 in materials. Most of the materials were found so they were free.
