A water balloon cannon including a barrel with a bore diameter designed to receive a water balloon. The barrel extends between a muzzle and a rear portion, where the rear portion defines a compressed air port and a water port. The water balloon cannon further includes a water valve for introducing a volume of water through the water port into the rear portion of the bore diameter, and an air valve for introducing a flow of compressed air through the compressed air port into the rear portion of the bore diameter. The volume of water is designed to act as a buffer between the flow of compressed air and the water balloon positioned within the bore diameter.

A loader and drive system are provided. The loader is preferably configured to house a quantity of projectiles (such as paintballs) in a chamber and supply the quantity of projectiles from the chamber to an attached pneumatic gun when in operation. The loader preferably includes an outlet configured to supply projectiles from the chamber to the pneumatic gun when the loader is operatively connected to the pneumatic gun. A drive system may be arranged in the loader and include a non-rotating center member arranged above the outlet with an entrance. A way may be arranged to direct projectiles into the outlet from the chamber through the entrance. An arm may be provided and attached to the center member to direct projectiles into the entrance. A driving member may surround the non-rotating center member and rotate around the non-rotating member. The driving member preferably urges projectiles from the chamber into the way and toward the outlet during operation of the loader.

The trigger position detection system in replica firearms comprising a sensor built from at least one light source D1 (5) and at least one receiver Q1 (6) converting the light signal into an electrical signal, wherein the light source D1 (5) and the light receiver Q1 (6) are located on a printed circuit board (7) in a way that they are deviated from the vertical axes running perpendicularly to the upper surface of the cylinder edge by an angle from the range of 0?-90?, and their active surfaces are directed towards the replica trigger (1).

A method of detecting the position of the trigger in replica firearms comprising controlling the light source D1 (5) in such a manner that at fixed regular time intervals, each time it emits light for the same period of time, while directing the beam reflected from the surface of the replica trigger (1) towards the receiver Q1 (6), which converts alternately the intensity of reflected light into an electric current and the intensity of the light reaching the receiver Q1 (6) from the environment of the replica or the intensity of only the light reaching the receiver Q1 (6) from the environment of the replica, the electric current flows through the resistor R2, generating voltage drop at its terminals, while in the analog-to-digital converter the resistor R2 voltage is converted into a digital signal and its value is stored in the buffer storing the last five results.

A variable velocity pneumatic launcher including at least one chamber filled with a projectile. The launcher includes a ballast chamber filled with pressurized air selectively released to propel a projectile from the launcher's barrel. The launcher includes a firing chamber filled with ambient air and a ballast chamber filled with pressurized air. A piston rod extends between the chambers and attaches to a firing piston and a ballast piston located inside the firing chamber and ballast chamber, respectively. The rod is connected to an adjustable velocity valve which controls the amount of longitudinal movement of the rod. When the trigger is activated, a portion of the pressurized air from the ballast chamber is delivered to the firing chamber. Because the surface area of the firing piston is greater than the ballast piston's surface area, the force exerted on the firing piston is sufficient to shift or displace the ballast piston and allow pressurize air to be released into the upper chamber containing the projectile.
