I've always loved the B-movie classic "Robot Monster". Not only was the acting sub-par, but the titular monster was just a guy in a cheap gorilla suit wearing a space helmet. Since I already had a cheap gorilla suit, I figured I'd make a helmet to go with it.
Step 1: Step 1-Get a Globe
I got mine at a local thrift shop for $5. I thought it would be made of plastic, but, lo and behold, it was made of cardboard.
Step 2: Step 2-Start Cutting
I cut two holes in the globe using a hefty pair of tin shears. I had the equator of the globe running from my shoulders around the top of my head, so I used the Arctic Circle as a guide for the "face hole". The hole for my neck I just eyeballed.
Step 3: Step 3-Stick Some Wooden Dowels on the Globe
I cut two wooden dowels about 6 inches long and screwed them onto the glove just a little bit in front of the equator at 10 and 2 o'clock. These are the bases for the antennae.
Step 4: Step 4-get a Bucket
I found an old 5-gallon plastic bucket in the desert near my house. It was pretty cruddy, but I scraped it and cleaned it out the best I could. I took the wire handle off to make it easier to cut.
Step 5: Step 5-cut the Bucket
I cut a whole in the bottom big enough for my head to fit through. Then I cut rouned shapes on either side to fit over my shoulders.
Step 6: Step 6-attach the Globe to the Bucket
I used PVC sealant, the kind you use to seal bathrooms to attach the two parts.
Step 7: Step 7-add Some Prop Pieces and Paint It.
The antennae are made of silver coat hangers with little metal balls glued on the ends. The wire is some old stereo wire I had laying around. I just glued the wire to the dowels and stuck the ends through a hole drilled in the back of the helmet. The "microphone" in the front is a pill bottle cap with some holes punched in it. The knob in the fron is another pill bottle cap glued on. The screen to hide my face is a sheer piece of black nylon, like from a nylon stocking. I painted the whole thing battleship gray, which is pretty much what the bucket was anyway.
Step 8: Step 8-Wear It Proudly
I wore my Robot Monster costume in front of my house while the trick-or-treaters were coming around. Not one person knew about the movie. I made up little movie posters on my computer to hand out, but most of the trick-or-treaters just ignored me. Obviously, they were more interested in getting the candy than finding out about some obscure B-movie from 1953. But I had fun.
