Hello 405th! Just finished up my ODST build and somewhere in the thread, the HALO Bio-Foam canister was brought up. This got me thinking and I decided to create my own thread as I go through this trial and error process. The overall idea is to have the ability to carry cold water at a con while keeping the look of the costume intact. Here are the images of what I have worked up so far. There is still quite a bit of finishing work that needs to be done, but so far, so good. I'll post more as the process comes along. Enjoy!
