how do they kill jaws in jaws 3
Jaws 3-D Hearing the shark has been lured into the pipe, Michael and Kay go down to repair the underwater tunnel, so the technicians can restore air pressure and drain the water. Calvin orders the pump to be shut down to suffocate the shark, but this act instead allows her to break free from the pipe and attack Michael and Kay, but they are saved by the dolphins. They make their way back to the control room, but the shark appears in front of the window and smashes through the glass, flooding the room and killing a technician. Michael notices FitzRoyce's corpse still in the shark's throat with a grenade, and uses a bent pole to pull its pin, triggering the grenade's explosion and killing the shark. In the aftermath, Mike and Kay celebrate with the dolphins, who survived their brush with the shark.
