Visible crew/equipment: At the very end of the episode, right after he tells Jesse how he used the red phosphorus to kill the gunmen, Walt leans down to vomit. You can see his microphone transmitter under his shirt. (00:54:20)
Visible crew/equipment: When Skyler is rubbing oil on her stomach and preparing herself in the bathroom, a camera and cameraman's hand is visible for about a second from the left side of the mirror. (00:10:30)
Green Light - S3-E4
Continuity mistake: In the scene where Walt is talking to Jesse in Jesse's car, when Jesse pulls out the bag of meth it is in a slide to seal bag. The bag changes between this and a regular ziploc bag from shot to shot. (00:19:30)
Visible crew/equipment: When Walter walks towards Jesse's house when he hasn't shown up for work a camera and boom microphone shadow is shown on his back. (00:40:10)
Continuity mistake: Mike Ehrmantraut takes Jesse to a house in the desert. He pulls up behind a dark blue car, which vanishes in the next shot, and then reappears.
Character mistake: When Walt steals the bottles of "hydrofluoric acid," they are misspelled on the labels as "hydroflouric." This misspelling is corrected when hydrofluoric acid reappears in season 4. This was corrected for some DVD releases but is still visible on some streaming services. (00:11:20)
...and the Bag's in the River - S1-E3
Continuity mistake: When Walt is sitting on the overpass it is clear that his car is parked on the part that straddles the median between the lanes, but when the shot is inside his car the view appears as if he is parked directly over the right lanes of traffic. (00:43:50)
Green Light - S3-E4
Continuity mistake: When Hank is standing between the ATM and the pumps at the gas station, the shadow cast by the roof over the pumps shifts between shots. The shot from away, taken next to the pole with the Indian logo was taken earlier in the day, casting a long shadow. The other shots have a higher sun which has moved by several hours.
4 Days Out - S2-E9
Visible crew/equipment: When Jesse declares he's going to start walking and sits up in the cot, Walt reaches out to him and a boom mic is visible at the top of the screen. (00:34:25)

...and the Bag's in the River - S1-E3
Character mistake: Hank finds the bag of meth in Krazy8's car. He picks it up to show Gomez and examine it. However, he does all of that in his ungloved hand. He then proceeds to place the meth in an evidence bag. (00:43:10)
Continuity mistake: When Walt is talking to Saul near the start, we see him unbalance the scales on the table in front of him then lean back. Camera cuts to Saul for a few seconds then shows Walt from behind Saul. In this angle, the scales are now balanced. (00:16:50)
One Minute - S3-E7
Continuity mistake: During Hank's interview, the tape recorder is constantly disappearing and reappearing on the table. (00:15:20)
Chosen answer: It is part of the ritual for la Santa Muerte. It is a sign of humility and sacrifice.
