Other mistake: This one is hard to describe. At the start of the movie, when Freeze and his gang are robbing the museum, Freeze looses his gun and it flies up to land on some sort of higher surface. However, it looks REALLY fake when it lands, perching right on the edge, which would be impossible for such a large weapon to do if thrown at that speed and from that angle. (00:05:25)
Other mistake: When Batman and Robin are falling after Freeze after they have jumped out of the rocket, Batman lands on Freeze and the diamond slips out of his grasp. However, you can plainly see that Arnold Schwarzenegger simply throws the diamond behind him. (00:11:55)
Other mistake: When Antonio Diego is being pumped up with Venom in Dr. Woodrue's lab, the tubes attached to the prisoner's head keep disappearing. It's in the shot where the camera pans from the foot of the exam table to Diego's (Bane's) right side. (00:16:50)
Other mistake: When Mr. Freeze threatens to freeze all of Gotham City, he has a big snowglobe in his hand. He freezes the snowglobe, then shatters it in is hand. When he crushes it open with his hand, the inside of the snowglobe is empty. There is no water, frozen or unfrozen, that comes out of the snowglobe when it breaks. (01:23:50)
Other mistake: While fighting Mr. Freeze (and Bane) at the Gotham Observatory, Batman, Robin & Batgirl all have batsuits on, with silver bat (or robin) symbols on their chest. But while they are giving Alfred the cure to Stage 1 of McGregor's Syndrome, for some reason they have changed clothes before giving him the cure. Because now (other than the fact that they have all taken off their masks) Robin has on his original robin suit (with the red robin symbol across his chest) and Batgirl has on a gray t-shirt. (01:55:25 - 01:56:15)
Other mistake: During the end credits when the listing for the vehicles go by, it shows "BATMOBILE, FREEZEMOBILE REDBIRD, BATHAMMER, BATSKIFF, and BATCYCLE BY TFX." There should be a comma between Freezemobile and Redbird. (02:02:05)
Other mistake: Apparently, guessing Alfred's password also turns computer monitors into projectors. Before Barbara guesses the password, none of the light/information on the monitor reflects off her, but afterwards, she might as well be a projector screen.
Other mistake: The two scientists that are frozen in the observatory stay frozen for more than eleven minutes, but when Batman heats them they are in perfect state.
Other mistake: Watch carefully during Freeze's opening heist: two of his goons accidentally check each other and nearly fall down. This can be seen on the left-hand side of the screen in the overhead shot (one skates next to Freeze, another skates around an ice spike) just as the camera passes a column. And where's that spotlight that follows Freeze coming from?
Answer: Maybe she drained the cryo-tube first? Maybe she did get wet but had dried off by the time we see her again? Maybe Bane did it for her? Pick whatever answer works best for you. It's a really small, insignificant detail in the film with plenty of potential answers.

Thanks though keep in mind she wouldn't have a clue as to how it works since she's a botanist not a scientist in cyro genetics.

She pulled the plug on the thing so Nora died and the tank drained (either automatically or Ivy did it). She just took the necklace off the body.
