I just finished watching BB for the first time. I watched the whole series in about 2 weeks, and I am enjoying it.

In the season 5 episode "Hazard Pay", Walter and the gang go looking for a new place to cook. One of the places they go to is a small box factory. I was excited at the first sight of it because I have worked in a box shop for years. Walter, having worked in a box factory in his youth, explains how a corrugator works.

Well, his explanation was wrong for 2 reasons.

• He says "it uses steam and salt to crimp kraft paper into cardboard" This is wrong. Starch is used, not salt.

• The machine he claimed was a corrugator, is not a corrugator. Here is a link of a real corrugator for comparison.

If the makers of Breaking Bad can get details like this wrong, what else do they get wrong. I was under the impression they had their science facts correct. It also worries me that if Walter can't tell the difference between salt and starch, maybe the meth he makes isn't so good.

Most of what was said in the scene is true.

• Saul: "If your in here when its up and running this place stinks already, you'll blend right in." -- True, depending on the paper.

• Saul: "It makes a hell of a racket when doing it which is great, right?" -- True, the noise level is close to 100 decibals.

• Walter: "When this thing is running its like a jungle in here." -- True, the paper gets heated to over 300°f and with the steam, it makes for a hot and humid environment.

tl;dr: Walter may know his Meth, but I know my boxes, bitch.
