Celery - How to have some more leaves after cutting all

A couple of weeks ago I bought celery to make some soup. I cut all the leaves and I was eager to try an experiment that I have seen before a couple of times. 

It is basically a type of propagation without having roots again. You just have to sink the stem (with no leaves) in some water (not too much) and wait 2-3 days to see the first leaves coming to life.

It worked for me perfectly, so I encourage you too to try and see the progress.

Have fun!
