When Dennis Nedry goes to steal the embryos from cold storage, he starts plucking vials out of the storage racks with his bare fingers. Embryos are stored in liquid nitrogen. Shouldn't he have brought along a pair of gloves?
Hang on - you're implying that the embryo tubes themselves were stored in DIRECT CONTACT with liquid nitrogen? At what, -50 degrees? I don't think so.
I agree with the point, though - even cooled indirectly they would have been too cold to handle.
The script-writers should have payed more attention to the book. In the novel, Crichton specifically says: "He [Nedry] pulled on a pair of heavy insulated gloves and opened the walk-in freezer marked CONTENTS VIABLE BIOLOGICAL MAINTAIN -10c MINIMUM."
This is definitely an error.
1. There is also a scene in the book where the T-Rex is shot with a tranquiliser, there's the whole Pterodactyl scene... are you trying to say that the scriptwriters forgot about _them_ when they wrote the script?
2. My freezer cools it's contents to -5 degrees and I can touch them easily enough. Do you really think another 5 degrees lower would matter? If they were only cooled at -10, Nedry would have had no problem touching them, therefore you're invalidating your own point :)
I have worked in labs with freezers that were -70C, which is pretty darn cold. This is where we keep the embryos. You really don't need liquid nitrogen for that but it looks a lot cooler in a movie! Anyway, in the course of working you would normally put on gloves to get in that freezer but I have done it before when I just needed to grab one thing and didn't need to handle a lot of stuff. It's cold but you can do it. If you held it a long time it would burn your skin (frostbite).
I agree that the lack of gloves was a slip up. The freezer says a minimum of -10 degrees, which means that it would be kept much colder, just in case someone was opening it a lot and the temperature started to drop, they would have to have some room for error. Also, even if you grab ice out of the freezer, the moisture on your skin often causes the ice to momentarily freeze to you. If Nedry had grabbed (bare-handed) glass vials kept below -20 it would have been a painful experience indeed.
