The revelation that galaxies are apparently distributed on two dimensional surfaces that enclose bubble-like voids (de Lapparent et al. 1986, Fairall et al. 1985) has raised considerable interest. We have started an ongoing program to identify and confirm the existence of such structures - as extracted from our redshift database and others. We are concerned to measure how close to sphericity the bubbles fall and, in particular, to see how well their centres can be located.
