Factual error: In a number of episodes people are shown eating and drinking in the laboratories. For instance, in "Miss Willows' Regrets" Nick and Greg are seen eating fried chicken in the lab, and in "Overload" Sara eats a sandwich while watching Grissom experiment with her deli pickle. There are other examples. No reputable laboratory (which this is supposed to be) would allow its staff to eat or drink while in the lab. It is basic scientific protocol to prevent contamination of samples or the person picking up toxins on their food.
Revealing mistake: Season 5 Episode 18 "Spark of Life": when they show a closeup of the badly-burned woman during her debridement, it can be seen that even though her eyebrows and hair and, in fact, 90% of her skin has been burned away, she still has long, full eyelashes.Rooster of Doom
Factual error: As has been noted, the problem with pressure differentials will make it impossible to flood someone's room with CO2 from sublimating dry ice anyway, but there is another problem. Dry ice sublimates at -78.5 C. That gas is going to be very, very cold and it will rapidly bring the temperature of the room down to a very uncomfortable level. Before a sleeping person suffocates they would be woken by the freezing cold.
Trivia: For those who don't (or can't) read American Sign Language, at the end of the episode, Grissom says to Dr. Gilbet is that his mother lost her hearing when she was eight years old. He once asked her what is it like to be deaf, and she told Grissom (who loved to swim) that it was like being underwater. She also taught him that being deaf does not make one inferior to others. Dr. Gilbert then replies that she teaches her students the same lesson.Cubs Fan
Question: Sarah asks Grissom to have dinner with her. Moments before, Grissom removes a card from his filofax thing for a 'Dr. Karen Roth'. I'm uncertain, but is this the blonde entomologist he had chemistry with in an earlier episode (they were discussing their mutual love of tarantulas, I think)? If not, who is it?
