Airlift Pump

It gradually lifts water using compressed air. It uses standard 1/4" aquarium tubing and pumps and is small+streamlined enough to fit through a pop bottle neck. It can lift water over five feet, using the cheapest air pump petsmart had... I now use several of these for watering plants on a timer.

Thank you gswatts for the inspiration!
