Boomerang: Carved from a 1" sheet of styrofoam. Paper mache'd over it 4-5 layers, then sanded, covered in 3 layers of mod podge, sanded some more, primed, painted yellow, and clearcoated with a layer of mod podge. Silver parts are 6mm craft foam, sealed with podge and painted silver. Red jewel is a red mancala bead, haha.
Picto Box: 2" pvc pipes and caps, cardstock, foamboard, a 4"pvc coupler for the lens, a 1/4" pvc coupler for the button, some silver thumbtacks for the rivets, and a chromed drain cover for the flash. A dead flashlight bulb sits in the flash.
Bomb: 10" styrofoam ball that was paper mache'd, sanded, mod podged, sanded some more, and primed/painted/clearcoated. The white part is a 4" pvc cap. The rope is a 1" tan synthetic rope, cut to length and the end painted with black acrylic to simulate a burnt fuse.
