Version 1.02 of the air-lift pump.
Due to the overwhelming reaction to the first instructable, here comes model II.
it has even fewer parts, it is easy & super cheap to build.
Can be used to lift gasoline, but please be careful for fire hasard.

List of parts;
A 3/8 inch or 10mm hose
a 4mm air hose( this hose should be longer than the 3/8" or 10mm hose)
an aquarium air pump for short hose (6foot)
or compressor ( far away)

Step 1: Slip the small into the big hose

Slip the small into the big hose, but not till the end.
Stop about 5 cm or 2 inches before reaching the end of the big hose.
