I'd like a way to easily (and cheaply) water my tomatos via a drip system. I built simple waterers using 2 and 3 liter bottles and wire hangers. My total cost outlay for this project was $1.16 for the drill bits.

Watering rates:
3-liter bottle: approx 48 minutes
2-liter bottle: approx 25 minutes

Step 1: Collect your supplies

1. Empty 2 or 3 liter bottles (rinse them before you start or this project gets kind of sticky in the middle)
2. Wire hangers
3. Box cutter or razor blade
4. Scissors sharp enough to cut plastic
5. Wire cutters
6. 1/16" Drill Bit
7. Drill
Put some string in the hole and the water should drip even slower.
