Cool Inspector Gadget Costume
Ran into the trench coat at a second hand store and got the idea instantly. The hat was made out of 1″ PVC tubing, bolt, nuts and washers, cardboard painted red for the propellors, and duct tape and electrical tape for strength and design. The propellors were glued onto a washer so they could spin on top of the hat. Extra padding was added inside the hat to make it more stable while wearing. Everyone loved it at the party I went to and I won best male costume at the party.
