Many complex costumes start from a simple and widely available material: cardboard. I’m continually impressed by what creative people can do with it, and Replica Prop Forum user Slagmite used it as the base for his Mr. Freeze cosplay. It was his first Bondo and resin suit build, and he invested about 150 hours in this first version of the costume. One of the neat aspects about the outfit is the light up hoses, and it was an easy solution:
The hose is the metal insulation from a length of scrap insulated wire and the lights are just LED rope that I wrapped around it. They are attached to a PVC canister on the back that I fill with hot water and dry ice. The Fog goes through the hoses and out through the entire suit. It only lasts for about 1 minute before I have to replace the hot water and a little more dry ice. Its more so for competitions instead of a regular trick. Works great. The fog is heavy and it’s cold.
