ALL fluids creep. but it's not magic.
All things respond to gravity. But what we for get is that while solids are effected by gross gravitation and only react to things like planetary gravity. fluids and glasses respond to everything.
The most obvious example is the tides. Even though the oceans are on earth the bulge out following the moon enough to raise and lower levels by several feet.
WELL with H you have something so light and small that it's close enough to the container that the containers gravity pull the H more powerfully then the gravity well of the planet.
In effect a super fluid is something small and light enough to consider all solids a flat plain. At least while in immediate contact to the solid.

A very good thread and message which shows that
Triodit is excellent in reasoning.
I would propose a simple test to see is it true that super liquids really go up the container beyond the adhesion force as in capillary action.
Just repeat the experiment with another container of same material and same inner diameter but with a thinner wall.
The gravitational attraction will thus be reduced while adhesion and other condition remain the same.
Will the critical weight of the super liquid found out to be reduced (the heaviest weight still able to climb up and leave the bottom completely)?

And I appreciate the shouts of
Triodit.
Really, just comment that You are right and I am wrong is useless and incomplete.
A responsible critic should TELL ME WHY I CAN"T BE RIGHT!!!
