The Jet Spray Firefighter gun is the newest arm against fire.
You’re at a fire, but your water pressure is too low, so the water stream can’t reach the target. This is where the Jet Spray comes to rescue. In the water gun is a gas canister that shoots out the nozzle and reels the hose out to the target. Once the nozzle reaches the target, it blasts water around and puts out the fire more efficiently than a regular hose could.
This gun would even be cool to have if you’re not a firefighter.
