Custom Torpedo Launcher
I disassembled a super squirter water gun and used the air pump and one-way valve for this. The hoses and trigger valves I had to order separate and hook together. A very simple design.
In reality, the torpedoes launched from a carrier don't go very far. It's just enough to clear the ship, and then the torpedo has its own guidance and propulsion units remotely controlled.
