This is one of my favorite garden accessories and gives the kids some responsibility in the garden. It is called a "watering can" and was a design prototype that came to fruition by Nicolas Le Moigne. It screws onto most bottles and intention was to repurpose PET plastic bottles. Since I don't buy plastic I reused one of my glass S. Pellegrino water bottles and works great. I bought this one at the Garden Gate down on the Arcata Plaza.
