!972.  9th grade, and just finished assembling an HW-101 and HP-23 power 
supply.  I wired the filter 'lytics in backwards and after about ten 
seconds, the caps split, and white borax dust was everywhere.  This was 
before the use of scored aluminum safety valves as is now common on many 
'lytics.  Not sure if that would have helped or made the dust situation even 
worse.
