Continuity mistake: In the first shot that shows a high view of Mr. Freeze standing on the stairs, his ice gun is pointed up. But, when it shows him again, the gun is resting in his hands. The next shot shows him bringing the gun into his hands again. (00:03:50)
Continuity mistake: The first confrontation with Mr. Freeze and his henchman involves them skating around a large ice covered area. The henchman are not using ice skates, but rollerblades. In the same scene we see ice skating blades pop out of Batman and Robin's boots, but when we actually see them skating, they are on rollerblades as well. (00:06:45)
Continuity mistake: In Dr. Woodrue's lab, two thugs carry Antonio Diego over to an experiment table and chain him to it. The thug on Diego's left has a cowboy hat on. However, just as that thug is pulling Diego's mask over Diego's head a few shots later, the thug's cowboy hat is gone. This same thug also disappears from the aerial shots of the lab as Dr. Woodrue is exclaiming over his genius of turning Diego into Bane, a super soldier, with Venom. Later, when Bane breaks free of his restraints, the thug just shows up out of nowhere to try to hold Bane down. (00:16:00)
Continuity mistake: When Dr. Freeze bends down to kiss his wife right before his accident, there is a tube of some sort behind her (in the distance), then as he kisses her the tube is gone. (00:20:15)
Continuity mistake: When Pamela Isley is reborn as Poison Ivy, she is covered in vines. One vine runs across her chest. After she kisses (and kills) Dr. Woodrue, the vine across her chest is gone. (00:23:45)
Continuity mistake: In the car on the way to the observatory, Pamela Eisley puts on a perfectly straight-haired and slightly red/pink colored wig. But when she is at the observatory, her wig is brown, has numerous fly-aways and has long bits on the sides. (00:32:50 - 00:34:40)
Continuity mistake: When Dr. Pamela Isley and Bane first arrive in Gotham City and are driving to the Gotham Observatory in their (stolen) red car, Dr. Isley is putting on a wig. When she grabs the wig out of the box and puts it on her head, you can see that she has black gloves on, but the gloves are missing when she is looking in the mirror and says to Bane "Gotham Observatory, Bane. And step on it." (00:34:05)
Continuity mistake: During the press conference, Julie's hand swaps from being lowered to brushing her hair between shots. (00:35:57)
Continuity mistake: At the observatory, when Bruce gives Dr. Isley's (Poison Ivy) proposal back. She grabs it with the printed part toward her, but in the next shot, she's holding the paper with the painted part facing away from her. (00:37:10)
Continuity mistake: Ivy extends the threefold invitation to the Botanical Garden event, but a shot later, it's folded and held against her chest. (00:38:00)
Continuity mistake: When Mr. Freeze crashes the costume ball, and shortly after he yells "Get the gun", Batman totally missed his first kick against the skating goon. It's painfully obvious even without slow motion. (00:44:10)
Continuity mistake: In one of the scenes when Freeze is going to take the diamonds from Ivy's neck, you can clearly see that he has no make-up in his neck (and it isnĀ“t an effect of the lights, he has really no make-up). (00:45:00)
Continuity mistake: When Poison Ivy first enters the Turkish Bath she is wearing a green top, tights and boots but as she is redecorating just after ejecting the gang members she now has brown tights and high heels. (00:59:10)
Continuity mistake: When Ivy blows her pheromone dust at the cop, her right hand is either holding the powder container or not, depending on the shot. (01:27:11)
Continuity mistake: When Robin steps foot into Poison Ivy's lair she is laid out on her flower bed. If you look at the sleeves of her costume, the ends of the sleeves are fringed in a simple leaf like design. Robin spurns Poison Ivy's affections, and an enfuriated Ivy pushes him into the lily pad pool. She is then confronted by Batman, and a soon to arrive Batgirl. Now - look at the huge, obvious, black rubber "thorn" bracelets that suddenly appear on each of her wrists. (01:37:25)
Continuity mistake: When Poison Ivy is talking to herself when she is leaving the observatory, you can notice that the policemen she pushed away have vanished in the background.
Continuity mistake: As Batman, Robin and Batgirl are heading to the Gotham Observatory to confront Mr. Freeze in their new Bat-Vehicles, a Frostbite piloting Mr. Freeze's Freezemobile meets them, crashing into two cars blocking the Freezemobile's way. The two cars the Freezemobile crashed into are gone in a later aerial shot of the Freezemobile having its freeze ray reflected back at it by Batman's shield.
Continuity mistake: Batman & Co arrive at Victor Fries' lair, and drive underneath it out of sight of the observatory on top, yet in the next scene, Victor is able to track Batman & Co's travel with the magnifying glass, which is impossible as they are already underneath he lair.
Continuity mistake: When Bat Girl and Poison Ivy are fighting by the lily pad pond nowhere can you see Robin who is still supposedly fighting the vines underneath it.
Continuity mistake: When Bruce and Julie go to the party in the observatory and are swamped by people, in the overhead shot at the start of the scene we can see that Gossip Gerty is trying to get to Bruce and Julie and that there is a man between Gerty and Julie. However, in the next shot (a tighter shot of the couple and onlookers), Gerty is suddenly right next to Julie, in the place where the man had been, with no time for him to move.
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.
