Abstract: An assembly for producing an artificial snowfall in a Christmas tree display arrangement is stored as a pack having a base 10 with a carrying handle 16 and a lid 18 adapted to fit over the base 10. Within the latter is an air blower unit comprising an electric motor and fan located below a cover 44, moving air from externally to a fan outlet 40 and thereafter into an air transporting tube assembly provided with a venturi, through an aperture 64 in the cover 44. A Christmas tree can locate through a central aperture 62 in the cover 44 onto a stand within the base 10. Artificial snow in the form of plastics beads is available on the cover 44 and can be moved through the venturi to the top of the tree, from where the beads fall by gravity through the tree to be collected by the cover 44 and its petal sections 52.
