Using hydrodynamical flows, we extract lipidic tethers from giant
unilamellar vesicles attached by one point to the tip of a
micro-rod. When a vesicle is submitted to a flow of constant
velocity U above a threshold velocity, a tube starts to grow
until it reaches a stationary length 
. The tube length,
L, and are measured as a function of time and U,
respectively. Simple theoretical laws fit our experimental data
reasonably well.
