Freezing Celery

My Mom taught me what to do when your celery gets rubbery. I used to just toss it, but if you put it in a jar or vase (I use a ceramic pitcher) full of water it looks brand new again. Sometimes I leave the celery standing up like that in the fridge (just cut off the bottom so it is easier to stand), or put it on the counter in water for 30 minutes or so before you use it for the same effect. Today I decided I wanted to freeze celery, but I didn't know if it was possible. I found it it was possible on thriftyfun.com Once frozen, you won't want to eat it raw but it will be ready for cooked dishes.
