Abstract: An apparatus for securing a collapsible water dam is an end-cap with a semi-cylindrical housing. The end-cap further includes a side flange coupled to each side of the housing at the bottom periphery of the outside wall of housing. The end-cap further includes a barrier wall inside the housing that creates a secure chamber for housing a collapsible water dam. The end-cap further includes a wall flange at the distal end of the housing. The wall flange couples to and joins both side flanges in a configuration that provides a tight fit with the end wall of a shower.

Abstract: A delivery device coupled to a drone can be used to distribute dry powdered materials to a target area. The powdered materials can be stored in a hopper having an auger at the lower end of the hopper. An auger motor can be actuated to transport the powdered material to an aeration chamber where the powdered material is mixed with turbulent air. The aerated powdered materials can then be emitted from the delivery device from a slinger disc onto a target area.
