  PLEASE DO NOT BREAK THE OUTER GLASS!

  You  will end up with lot of shortwave UV AKA UV-C. Photoresists are
  sensitive  (peak)  arround  340  nm  AKA UV-A. Also with outer shell
  removed,  you  will  generate  lot  of  ozone (O3) which reacts with
  haemoglobine  in  your  red  blood  cells  and other cells that need
  oxygen can not use in 'cause it's not O2.

  UV-C  can produce severe skin damage and is 'tethal' to your retina.
  Irreversible sight damage.
