A water intake system for a boat spray gun, including a system utilizing a port through a transom of a boat, the port positioned proximate to the bottom portion of the boat; a spray gun system; and a water intake system, comprising: a first water inlet tube having a proximal end connectable to a pump of the spray gun system and a distal end connectable to a swivel; a second water inlet tube having a proximal end and a distal end, the proximal end connectable to the swivel; a port connector connectable to the distal end of the second water inlet tube, the port connector having external threads threadingly engaging the port of the boat; and a water inlet conduit having a proximal end engageable with the port connector and a distal end positioned under the bottom portion of the boat.

Provided herein are fluid jet enhancement adapters for use with a propellant driven disrupter. The adapter may comprise: a first end operably connected to a muzzle end of a propellant driven disrupter barrel and a second end, wherein a longitudinal region extends between the first end and the second end. The longitudinal region has: a longitudinal region inner surface that defines a longitudinal region lumen; a longitudinal region outer surface opposably facing the longitudinal region inner surface, with a longitudinal region wall having a wall thickness that separates the longitudinal region inner surface from the longitudinal region outer surface. The longitudinal region lumen has a first end inner diameter that is substantially equivalent to a muzzle inner diameter. The longitudinal region wall forms a continuous surface that radially isolates the longitudinal region lumen from a surrounding environment.

A liquid jet ejection device is provided. The liquid jet ejection device has a flexible lumen having an intake end positioned to be in fluid communication with a liquid source, and an output end distal from the intake end. A pump is coupled to the flexible lumen, the pump being actuatable to eject a liquid from the liquid source via the output end. A body structure extends from a handle and supports the output end of the flexible lumen, the body structure having a base form in which the output end of the flexible lumen is supported in a base pose relative to the handle, the body structure being deformable from the base form via contact with an object, the body structure returning to the base form upon withdrawal of contact.

A drone for deterring intruders within a monitored area includes a multirotor aerial vehicle with an electric drive apparatus and a power supply configured to provide electrical energy. A controller is configured to control the multirotor aerial vehicle. A first sensor is in electrical communication with the controller, the sensor configured to provide navigation information to the controller. A wireless communication circuit is in electrical communication with the controller, and in wireless communication with an external wireless transceiver. A deterrence effector bay is in electrical communication with the controller. The deterrence effector bay includes a non-lethal deterrence effector and an actuator. Activation of the actuator causes the delivery of the non-lethal deterrence effector to a target. The drone may be used in conjunction with an alarm system as a deterrent against intrusion.

Provided herein are fluid jet enhancement adapters for use with a propellant driven disrupter, and more particularly muzzle blast suppresser. The fluid jet enhancement muzzle blast suppresser may comprise a suppresser bore extending between the proximal end and the distal end with an inner suppresser surface that defines the suppresser bore. An outer suppresser surface opposably faces the inner suppresser surface, with a suppresser chamber positioned between the inner and outer suppresser surfaces. A plurality of passages connect the suppresser bore with the suppresser chamber, wherein the plurality of passages are sized to allow gas to move from the suppresser bore to the suppresser chamber and minimize liquid movement from the suppresser bore to the suppresser chamber.

The invention relates to a toy for discharging a liquid. The toy comprises a discharging chamber adapted to receive a liquid from a liquid storage tank; an outlet arranged at the discharging chamber adapted to discharge at least some of the liquid received in the discharging chamber, the outlet being controllable by a covering mechanism movable between a closed position and an open position to thereby close and open the outlet, respectively; a movable member operably connected with the covering mechanism; wherein, in response to a triggering action of the toy, the movable member is movable from a first position to a second position thereby actuating the covering mechanism to move from the closed position to the open position, and at the same time, triggering discharge of the at least some of the liquid from the discharging chamber via the outlet.

A toy may include a target having a target magnet and a first color configured to become a second color when the target is activated. The toy also may include a backing having a backing magnet configured to be mounted to an interior of a garment. The backing may be magnetically attracted to the target magnet through the garment when the target is on an exterior of the garment. The target may be configured to be retained on the garment only via magnetic force between the target magnet and the backing magnet. The target and the backing may be configured to be readily removed from the garment and have numerous re-uses for future play.

Apparatus includes one or more fillable containers (35) in fluid communication with a primary channel (32), which is in fluid communication with a fluid entrance opening (31) which is attachable to a fluid source. The fillable containers (35) are made of a material that ruptures upon propelling the fillable containers (35) against a target. Each of the fillable containers (35) includes a one-way valve (33) that allows fluid to flow through the primary channel (32) into a corresponding one of the containers (35) and to seal each of the containers (35) with the fluid therein.

Provided herein are shaped charges for focusing a fluid mass and related methods of using the shaped charges for disruption of an explosive target with a spherical projectile. The shaped charge comprises a plastic shell having a special geometric shape configured to support a shape-conforming explosive. A cylindrical plastic body has an interior volume for containing a fluid and the plastic shell. The plastic body closed distal end has a geometric shape that is substantially matched to the shape of the plastic shell. Metal spherical projectiles having an outer layer of metal selected to have an effective density matched to the fluid provide advantageous target disruption capabilities.
