Bubble Water Pump
thingiverse
This device takes an air hose input and creates a trickle of air and water up the output hose. Connect your tubes by pressing them into the holes and then submerge in water. I've found it takes about 7 inches of water for adequate pressure to function. I'm using this with an aquarium air bubbler to lift water up 7 feet to feed my hydroponic system.
