I brought home some empty IV bags and tubing instead of throwing it away at work (I am an RN in the ICU). I rinsed out the bags and refilled with water. I am using them to drip irrigate my overwintered geranium and other houseplants. The roller clamp on the IV tubing lets me adjust the amount of water just right.
I also brought home some containers that hold pre-filled syringes. Great containers for my homemade newspaper pots. My best ones fit directly on the windowsill.
