Revive Wilted Celery

How many of us have bought celery on sale and stashed it in the refrigerator only to reach for it later and find it wilted and sad looking?
I figured how to revive celery by thinking of it as cut flowers, it's thirsty and needed water!
Trim off a bit of the root end of the celery stalks and immerse them into a tall glass of cold water. In an hour or so, the stalk will be crisp and standing tall again ready for use!
