MT - If at first . . .

. . . you do this week’s MonoMonday photo last week, then you really have to repeat it this week!!
 
I think that you can see that this bottle is ABSOLUTELY EMPTY.  Just to keep in the spirit of the challenge I have thrown some light onto the problem; or should that be into??
 
Many thanks to 60plus for hosting this month’s MonoMonday challenge.
 
(This looks better in large)


ps - I have been asked how it was done - see Clive1079 below for answer . . .
