Adding on to what Oscar said. If the crossair is a sprite, then you could probably spcol the crossair and the bottle then type:
SPCOL 0 'Whatever management number your crossair sprite is
SPCOL 1 'Whatever management number your bottle sprite is
IF SPHITSP(0,1) THEN
IF BUTTON() AND #B THEN SPHIDE 1
ENDIF
