As Halloween approaches, we’re going to post some costumes and spooky goodies to make – Here’s a fun costume based on the game “Operation”. Felxis writes “Basic supplies – this is what I started with. Wire, a battery, doorbell, Krazy glue, velcro, some markers, Scotch and electrical tape. The metallic items are outlet covers, which I got from Home Depot. Really, any sort of metal will do; I just happened to like the box shape of these guys, and they make grabbing the candy a little harder”. Link. I like how it’s wired up to a doorbell buzzer.
