Sometimes you just need to give a costume or a prop replica a little extra oomph — that’s where a tiny fog machine comes in handy. Valkyrie Studios came up with a tutorial for crafting the device with parts such as a breakout board, a mini fish tank air pump, a LiPo battery, and a few more items. The above video shows the fog machine as part of a costume, and the video below gives a straightforward look at how the little fog machine works. It’s portable enough to attach to the hilt of a prop weapon or to tuck inside a costume. You’d have to refill the fog juice on a regular basis though.
