On a recent trip home I found one of my early creations!  This is a centrifuge I built on or around 1993, though its hard to be sure.  I still remember the original design.  It had wire cages to hold the glass tubes.  Mechanical failure resulted in an arc of milk and glass embedded in the kitchen wall.  After that I replaced the wire frame with a block of wood which proved much “safer” until I tired of centrifugal separation.
