Grow your own Green Onions!

So, you went to the store... Bought some green onion...chopped it up and had a stub. Toss it? Or.. Grow again on your kitchen counter?
Takes a couple days but you can "recycle" your green onion as long as you want just remember to change the water every day or two! I know it's cheap but its convenient? Cool? Fun for kids?

Needed:
Green onion stalk, preferably with roots.
Small cup or glass.
Water.

Whenever I need I just take my scissors and cut a piece :)

Enjoy!
