This could be a double definition.

'still' is the first definition.

(Other definitions for static that I've seen before include "fixed" , "Steady" , "Crakling or hissing noise caused by electrical interference" , "That's shocking!" , "Not moving - electrical interference" .)

I've seen this clue in The Globe and Mail.
