The lid of the Junior Dynamite Blaster proudly boasts "Selected by Science and Mechanics Magazine as one of the Ten Best Toys of 1958." Using a detonator, the demolitionist pumps air into the blaster assembly which has been topped by plastic rocks or any light-weight substance that remains harmless in flight. The manufacturer lists suitable materials for blasting in addition to the styrofoam "rocks" it supplies: empty cereal boxes, empty cigarette packs, clothespins, plastic building blocks, empty milk cartons, tape and thread spools, and plastic dishes and boxes. As Kilgore prints on its instruction sheet for the Junior Blaster, "Blasting is fun!" Few kids (or adults) could resist the appeal of this toy.
