If you are planning on dressing up as a devil, a demon or even Poseidon, the Greek god, your costume will not be complete without a trident. However, purchasing costumes and costume accessories can get expensive very quickly. Luckily, with a visit to your local craft and hobby store and the use of a few household items, you can make your own trident for a fraction of the price.
Things You'll Need
Hot glue gun
1 craft foam cut to an 8-inch by 2-inch rectangle
3 craft foam cones
Use the hot glue gun to glue the craft foam rectangle to the end of the broomstick. This will serve as the base for the trident spikes.
Cut your cones to size if necessary, and glue the first cone in the center of the foam rectangle.
Glue another cone on each side of the center cone. You should now recognize the skeleton of your trident.
Wrap duct tape around the foam area entirely to reinforce it as well as give the paint something more substantial to stick to than foam.
Use spray paint to paint your trident. If you are matching it with a Poseidon costume, spray paint the entire trident gold. If you are matching it with a devil or demon costume, you could spray paint the entire trident black or red, or do a combination of the two colors.
