Castlefield Gallery Project Space residency. Above perpetual bubble detail - here you can see the tube to balance pressure inside the bubble.

Soap bubbles have a finite existence due to several factors; Firstly the soap film slowly thins and weakens, as this happens the colours change as different wave lengths of light are refracted until finally there are no colours left, Black [transparent] spots develop on the film, at these points the bubble wall is now less that 25 nanometers thickness. This makes the spherical structure unstable and eventually it pops.

If an environment is created free of dust and turbulence, where the moisture levels can be maintained at 100% - theoretically there is no reason why the bubble should not last forever. Additionally air permeates through the bubble wall so, it shrinks. A tube inserted inside the bubble allows balancing the internal pressure of the bubble. A soap bubble in stasis like this, becomes totally colorless, a sad shadow of its former self, to the point that it is almost totally invisible.

Capillary action
Referencing an experiment by CV boys, Liquid creates parabolic curve between glass plates. variations of this are made by using different sized glass plates and adjusting the separation distance.
Glass plates, clamps, small puddle of liquid, food colouring, wooden shelf.
