Trivia: Director Joel Schumacher, feeling he had let down fans somewhat due to the film being so light-hearted and campy, wanted to direct another entry in the franchise that would be darker and more along the lines of the first two Tim Burton films. He expressed interest in pursuing a film following the character Scarecrow, which would also feature a return of Jack Nicholson's Joker from the original film. (In a dream-like role as a representation of Batman's fear due to Scarecrow's fear-toxins.) Schumacher also expressed interest in pursing an adaptation of "Year One" or "The Dark Knight Returns", again so he could give the fans a darker film closer to the comics. Eventually, the series was instead rebooted.
Trivia: Director Joel Schumacher stated that the producers demanded the film be "more toyetic"- a term he had never even heard of. When asked what they meant, he was informed that it meant the film should be able to easily be merchandised and made into toys, games and other tie-in products for children. It has also widely been reported that toy companies were brought in early in production, and given final approval over the designs used in the film, based on what would make for the best and most potentially profitable toys for children, to the dismay of the cast and crew.

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.
