Light Up Robot Costume

My 6 year old son wanted to be a robot - so we went with the classic box robot look. I cut and attached to boxes and then painted an decorated them. We used lots of colored tape, bottle caps, gage print-outs, etc. We also added battery string lights poking them through from the inside. We also used push lights for eyes and a fiber optic light for hair. We added the tubing on the arms and legs...but that made it kind of hard to walk! We cut big openings at the mouth and ears for safety, and added black netting to cover it.
