Principle of water gun: In effect, a water pistol works on the same principle as a water pump. When you pull the trigger and the piston pushes it in, it decreases the volume inside the gun, which forces water out through the nozzle.
Principle of the dart gun: The plunger works by sucking air and loading the gun barrel with pressure. When the trigger is pulled, the pressurized air sends a dart into a trajectory and the higher the pressure, the faster and farther the dart shoots.
Principle of the crossbow: A crossbow is a ranged weapon using an elastic launching device consisting of a bow-like assembly called a prod, mounted horizontally on a main frame called a tiller, which is hand-held.
Principle of the taser gun: The Taser fires two small darts, connected to the device with thin wires, up to a distance of approximately 35 feet. The darts can penetrate clothing and, once they make contact with the target, deliver the electric shock, which disrupts the target's nervous system, resulting in temporary incapacitation.
Principle of the gas gun: When the trigger is pulled, a hammer inside the gun will push against the valve in the magazine for a short period of time, causing gas to be released into the top portion of the weapon and propelling the BB out of the chamber.
Principle of the firearms: In firearms the high-pressure gas is generated by combustion, usually of gunpowder. This principle is similar to that of internal combustion engines, except that the bullet leaves the barrel, while the piston transfers its motion to other parts and returns down the cylinder.
Principle of the rail gun: The basic principle behind a railgun is that it uses an electric current to create a magnetic field. This allows the railgun to shoot projectiles made from conductive materials.
Principle of the laser gun: Directed energy weapons (DEWs) are defined as electromagnetic systems capable of converting chemical or electrical energy to radiated energy and focusing it on a target, resulting in physical damage that degrades, neutralizes, defeats, or destroys an adversarial capability.
Principle of the rocket launcher: All jet engines, which are also called gas turbines, work on the same principle. The engine sucks air in at the front with a fan. A compressor raises the pressure of the air. The compressor is made with many blades attached to a shaft.
