Abstract: Described herein is an explosive casing, cartridge or housing, as well as a method of making same, for a small explosive or firecracker such that when fully assembled results in a tetrahedron or pyramidal, 3-D structure that provides an enhanced explosive sound and bursting strength.

Abstract: A collapsible and portable fireplace apparatus is described herein that includes a housing that is expanded and opens to create an open space for forming a fire, the housing being supported by a lightweight base wire frame assembly that also maintains the housing in an expanded state while in use. Once the base wire frame assembly is removed, the fireplace easily folds or collapses at a number of pivot points for ease of storage and transport along with the wire frame assembly. For improved operability a shelf grate is provided within the open space of the housing to support the fuel above a base panel to allow air to circulate under the burning fuel.
