While on a mapping mission, the Enterprise receives an outdated transmission from the volcanic star Cepheus. A flash of light from the planet passes through the ship and disables all dilithium crystals. Soon thereafter, the crew begins to shrink. With no cure in sight, it becomes increasingly difficult for the Starfleet officers to handle the ship's controls. Written by

A normal sized human has about the same density as water which is why normal sized humans are are neutrally buoyant in water (more or less). Having shrunk when Nurse Chapel falls into the aquarium she is seen sinking like a stone. This is correct because her size is smaller but her mass has not changed. This would mean she is now much more dense than she had been. She would not have been able to swim back to the surface of the water to call for help. She would have drowned before anyone could have helped her.
The water would not have changed density because water is not organic. See more
Engineering. No casualties, captain, but trouble aplenty with the engines. Every dilithium crystal connection smashed in the warp engine circuitry. We're trying to bypass them now.
Captain James T. Kirk
What about main circuits?
Well you have ta see it to believe it, sir. Those big crystals in there have come apart. Each of them, unpeeling like the rind of an orange.
