I am not meaning freeze by ice, I mean freeze by stopping something and making it unable to move. as far as levitation concentrate on something and picture it lifting into the air, it is best if you point at is that way you can focus you concentration and direct it.
Stop something? *smiles* You said I already did that with those pillows!
*takes a small stone and puts it down in front of her*
*points at it and concentrates*
Yes I know you did, but it dropped from the air immediately, I want you to be able to stop something and leaving it where it is at.
*watches kex and the stone*
*pauses and thinks about that* Oh - okay! Wait - I stopped these shards from falling down on the cats! *smiles*
I'll try to make it lift more slowly this time!
*concentrates again*
*the stone slowly lifts up into the air, higher and higher*
