Freezing water

Hydro-Cryokinesis is the ability to freeze water. The best known mermaid who has this power is Emma Gilbert. Emma first discovered this power when Cleo was first demonstrating hers. Cleo created a tower of water but lost focus and was about to fall on Emma and Rikki. Emma put her hand up to protect herself and unintentionally froze it. She then did it again moments later with a jar of water a few feet away. There is a disadvantage to this power because although water can be cooled down and frozen the mermaid with this power has no control of the waters movement. This power can be used to create ice, cool down hot objects or even lower bodily temperature. It can be combined with hydrokinesis, to create a ice ball as seen in "A Twist In The Tail." The hand movement for this power is a stiff "stop" sign similar to the English sign language for the letter "B". This may symbolize that when Emma is doing this she is slowing down and stopping the water molecules. If the mermaid with this power is in the moon pool during the planetary alignment, it is enhanced to Cryokinesis, and the ability to create blizzards.
