Bubble lift hydroponics

This is an old project from 2000, so please excuse the low res pictures. This is a hydro setup similar to my recirculating hydroponics with the exception that it uses an air pump instead of a water pump.

Step 1 Parts

You'll need
a pair of buckets, check you local grocer's bakery, they'll often have them for free or a buck.
a lid
an air pump
window screening
a piece of pex tube 3/8ths
aquarium tubing
1/4 inch irrigation connector
perlite

optional
grommet
barbed hose elbow
clear tubing.

So.. You push air into this PEX tube that's in the water, and then water gets pushed up several inches? How does that work?
