This Halloween I made a Baymax costume! For those who don’t know, Baymax is the medical robot in the Disney movie Big Hero 6. I built the costume with 2mm thick trash compactor bags from Walmart, clear tape, cardboard, and a powerful computer fan I found on Ebay (the BFB1012VH). The fan runs continuously, and is powered by a lipo battery in my pocket. The mask has some mesh between the eyes for me to see through.
