When Hodgins prepares the shotgun to fire the test shot, he racks the shotgun twice.
Hodgins explains that the screwdriver made from beryllium has a melting point of 865 Celsius. This is the melting point for beryllium copper alloy. Additionally, he states that yellow brass has a melting point of 905 Celsius. This is incorrect, as yellow brass melts between 905 and 932 degrees Fahrenheit. This factual error is furthered by the images presented which show a melted screwdriver but an intact shell casing. It takes approximately twice as much heat to melt beryllium copper alloy than it does yellow brass.
When hodgins sets the booby trap and cam opens the door you can see the actor who plays booth close his eyes before he is covered in jelly showing he knew about it before it happened.
Right after hodgins test the homemade shell there is a scene with a red truck and the crew and camera are reflected on the bumber.
When the FBI interviews Carlene Blayney, a Marine, she says that she and Deanna met at "basic training". She also refers to Deanna as a "soldier". Marines refer to their initial training as boot camp or recruit training; "basic training" is a term common in the US Army. Additionally, no Marine would ever refer to themselves as a soldier.
Bones and Saroyan both refer to benzodiazepine in the singular, and include an actual bottle labeled Benzodiazepine as evidence. Benzodiazepine is not an individual drug, however; the term refers to the entire class of psychoactive drugs (which includes such brand names s Valium, Klonopin and Ativan). It would be correct to say "a benzodiazepine," as in any one drug in this group.
