### Clue: Where ladies go – a place for explosive stuff (6,4)
### Answer: POWDER ROOM 
 ### Explanation: Definition: Where ladies go
  Whimsical expression for a room,*place* where gunpowder and other *explosive stuff* are stored.  Properly called a gunpowder room.
Defn:  Euphemism for the *ladies'* loo, where they go to supposedly powder their noses.  Nice surface with the "powder" bit.
