CSI: Miami

Goof: Towards the middle of the episode, a lab tech makes the comment, "since oil is heavier than water." However, oil is in fact lighter than water.

Goof: In the early analysis of the crash, Horatio goes through the sequence of events leading to the crash with a model airplane in his hand. He incorrectly states that after the valve is detonated, releasing the chemicals, the center of gravity shifts aft (towards the back of the aircraft), causing the plane to pitch up, stall, and then crash. In fact, it is quite the opposite. Since the cargo was loaded in bladders in the aft end of the airplane, the center of gravity would already be aft, compared to an "empty" plane with just the pilot. With the cargo gone, the center of gravity shifts forward, causing a pitch down. This effect would have been compounded by the fact that the airplane would have had some nose-down trim added to counteract the aft center of gravity. The real result would have been a nose dive to the ground – not a stall – with the angle depending on the nose-down trim setting.

Goof: The equation on the pillows for the fuel cell, even if fictitious, does not add up. On the top right corner it has "2H2O+O2 => 2H2O," when on the bottom left of the pillow (and more correctly) it states the net is "2H2+O2 => 2H2O."

Goof: Horatio points out that a suspect has a drop of potassium permanganate on his shoe. Potassium permanganate is a purple solid, and even in low concentrations, the solution is rather purplish. Yet the liquid shown was clear.
