Here are various demonstrations and uses for net launchers and liquid launchers. These non-lethal weapons can be used to slow down or subdue criminals. When used together or used with other non-lethal weapons (such as the 2-pronged weapons called a "riot forks"), they can be very powerful tools for law enforcement, security, and individuals.Reminiscent to something you would find in a live-action superhero television show, the net launcher is a handheld device that shoots out a net projectile. The launcher is reloadable and has two different net cartridges. One type of cartridge just fires out a net. The other type of cartridge fires out a net with a line that can be pulled. The launcher has a built-in alarm to alert others that the device has been fired. The net can be fired from 2 to 3 meters from the intended target. The launcher has obvious limitations and will only work properly when the intended target is in the open and can be fully wrapped up by the net. The device could potentially allow a victim to escape from an approaching attacker. When two or more nets are used together, the criminal will be completely engulfed in netting and will have a very difficult time trying to escape.The liquid launcher is a handheld device that rapidly shoots out liquid from two tiny canister cartridges. The liquid launcher can hit targets up to 5 meters away. There are two different types of cartridges. One cartridge contains a liquid similar to pepper spray, and it can be used to slow down or stop a criminal. The other cartridge contains a bright marking liquid that will glow under ultraviolet light, and it can be used to mark a criminal (or attacker) or the vehicle the criminal is attempting to escape in. Depending on the application of the weapon, the two different types of cartridges can be used separately or can be used simultaneously.
