The demonstration kit may include a spray assembly and a control assembly. The spray assembly may include a case having a base and a cover rotatably coupled to the base, a plurality of back wall panels configured to be secured to a sidewall of the base, a boom connected to an interior surface of the case, and one or more nozzles connected to the boom and repositionable along a length of the boom. The control assembly includes at least one pump that when in an operating orientation is fluidly connected to the one or more nozzles and a portable power supply in electrical communication with the at least one pump. ## Claims ### Claim 1 A demonstration kit comprising: a case having a base and a cover connected to the base, the base and the cover moveable relative to one another to define an opened position of the case and a closed position of the case; a boom connected to the case and manipulatable between a collapsed position when the case is in the closed position, and an extended position when the case is in the opened position; one or more nozzles coupled to the boom and repositionable along a length of the boom; a plurality of panels positioned relative to the case and configured to block spray from the one or more nozzles; and at least one pump that when in an operating orientation is fluidly connected to the one or more nozzles. ### Claim 2 (depends on 1) The demonstration kit of claim 1, wherein the plurality of panels comprises a plurality of back wall panels and a plurality of side wall panels, and wherein the plurality of panels are secured or configured to be secured to the case. ### Claim 3 (depends on 1) The demonstration kit of claim 1, further comprising a splash guard configured to be secured to a sidewall of the case. ### Claim 4 (depends on 1) The demonstration kit of claim 1, wherein the boom is rotatably coupled to the case. ### Claim 5 (depends on 1) The demonstration kit of claim 1, wherein the at least one pump is arrangeable outside of the case. ### Claim 6 (depends on 5) The demonstration kit of claim 5, further comprising a control assembly separated from the case and configured to house the at least one pump. ### Claim 7 (depends on 1) The demonstration kit of claim 1, wherein the base is fluidly connectable to an external fluid source. ### Claim 8 (depends on 7) The demonstration kit of claim 7, wherein the base is fluidically connected to the external fluid source in a manner to define a circulation path for the fluid between the boom and the base. ### Claim 9 (depends on 1) The demonstration kit of claim 1, wherein, in the collapsed position, the boom is positioned within a cavity defined by the cover, and in the extended position, the boom is positioned proximate a top edge of the cover. ### Claim 10 (depends on 1) The demonstration kit of claim 1, wherein at least the case, the plurality of panels, the boom, and the one or more nozzles collectively define a portable spray assembly. ### Claim 11 (depends on 1) The demonstration kit of claim 1, further comprising a portable power supply in electrical communication with the at least one pump. ### Claim 12 (depends on 11) The demonstration kit of claim 11, further comprising a control assembly adapted to control the at least one pump using a pulse width modulation signal. ### Claim 13 (depends on 1) The demonstration kit of claim 1, further comprising a dampening assembly configured to dampen fluid flow caused by the at least one pump. ### Claim 14 A method of using a spray demonstration kit, the method comprising: arranging a case having a base and a cover to an open position by moving at least one edge of the base away from the cover; and when the case is in the open position: positioning a plurality of panels relative to the case; moving a boom coupled to the case from a collapsed position to an extended position, the boom coupled with one or more nozzles; and causing at least one pump that is fluidically connected to the one or more nozzles to spray a fluid from the one or more nozzles coupled with the boom. ### Claim 15 (depends on 14) The method of claim 14, further comprising positioning the one or more nozzles on the boom. ### Claim 16 (depends on 14) The method of claim 14, further comprising arranging the case in a closed position by moving the at least one edge of the base toward the cover. ### Claim 17 (depends on 16) The method of claim 16, wherein the boom is positioned with a cavity defined by the cover when the case is in the closed position. ### Claim 18 (depends on 14) The method of claim 14, wherein: the boom is rotatably coupled to the case; and the moving of the boom comprises rotating the boom from the collapsed position to the extended position. ### Claim 19 (depends on 14) The method of claim 14, further comprising receiving the fluid sprayed from the one or more nozzles at the base, and causing the fluid to exit the base. ### Claim 20 (depends on 14) The method of claim 14, wherein: the method further comprises connecting the at least one pump to a control assembly separated from the case; and the causing of the at least one pump to spray the fluid comprises using the control assembly to generate a signal that actuates the at least one pump.
