Onions and Celery

I have been missing out all these years.  Did you know that you can re-grow your vegetables...the ones that are getting really gross in your refrigerator?  I saw several posts about this...re-grow your green onions, re-grow your celery.  So on Sunday, when I was doing the twice yearly refrigerator purge and clean...I decided to give it a try..old celery AND old green onions at the bottom or the hydrator (do people still call it that?)

I trimmed off the really gross stuff and put them in water.  And five days later this is what I have...who knew?

We used the onion tops tonight...I'm not sure about the celery yet...maybe I need to plant it...in dirt?  Anybody have any ideas?    But I love that I can actually recycle/reuse my rotten vegetables :).
