The grand plan for my Mysterio costume is to have a backpack worn fog generator using dry ice. (I’m not sure I’ll have time to get the fog generator or the strobe lights working, as I don’t even have the jumpsuit or boot covers finished yet, but I had the PVC parts so I started work on it.)

The Plan: Have warm water in the pipe–possibly with a loop of plastic tubing wrapped around my torso fed by a pump, which would have the dual effects of keeping my special effects water near body temperature, and cooling me off, which is important in Atlanta in the summer. I’ll have a basket of dry ice inside the tube that can be lowered using string, and a fan blowing air down the top of the pipe. The Dry-Ice Fog will billow out the sides of the T pipes and look really cool emerging from under my cloak. (How I wear the fog generator is not yet part of the plan, but I’m imagining something like a backpack, or suspending it from my cowboy collar.) It will be mostly hidden under my cloak, but since I had the emerald green spray paint left over from my color matching paint buying discovery, I decided it should be color coordinated.

Cost saving measures: I bought $5 worth of PVC parts (a 4″ piece of low pressure tube, a “knock-out” cap to seal the bottom, and a 3″ to 1 1/2″ 4-way adapter. By using the $1 knock out instead of a full 4″ PVC cap I saved several dollars and made the bottom of my fog generator “flat” instead of rounded. As it will not be under any pressure other than the weight of the water and dry ice, it should hold fine. [And if it doesn’t, I always have my “Uh oh, I think my water just broke” joke all lined up.]
I also saved money (and bulk) by using a 3″ 4-way adapter, instead of a 4″ one. A 3″ PVC pipe will fit perfectly inside of a 4″ PVC pipe if you rasp off the small protrusions. (The fact that I was informed of this by a “plumber” also shopping in the Home Depot plumbing aisle slightly scares me….but since I’m not actually running pressurized water through it, and it saved me another five dollars, I decided to follow his advice.)
