You know how you pin tens or hundreds of those "clever/need to do this/didn't know this/why didn't I know this" kinds of ideas on Pinterest? Ever try them out? Did they actually work?
Here's one less one to wonder about. I put this Pin to the test: After slicing up your green onions, save the white ends, submerge them in water, place in a sunny window, and watch them replenish themselves.
This picture was taken one week after I dunked those little white nasties in water. And look what happened! I felt like I was in my own little mini-mythbusters episode.
