Visible crew/equipment: Just after Robin and Batgirl have dropped down to a ledge beneath the Gotham Observatory in the final fight scene, Bane appears behind them and grabs them by their necks. You can see the light reflected from the camera crews' lights on the icy wall on the right side. (01:43:05)
Revealing mistake: When Batman places the heaters around the telescope to thaw the ice, the frozen floor moves like plastic when he places the second heater. (01:45:00)
Alfred: There is no defeat in death, Master Bruce. Victory comes in defending what we know is right while we still live.
Trivia: After filming "Terminator 2: Judgment Day (1991)," Arnold Schwarzenegger stated that he would never play a villain again, but he did for this film.
More questions & answers from Batman and Robin
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.
