Portable Flower Pots

In a few weeks we plan on doing an activity about self-reliance and gardening.  We've instructed the girls to come up with a 2 liter pop bottle and bring it to the activity so we can do something similar to this.  (More to come about this after this activity is complete!)
 
And this morning when I saw Pioneer Woman's Blast from the Past post, I thought this would make a treat to serve at the end!

You could also do dirt and worms if you don't want to get too fancy.
