Rover owners: DIY easy bleed

After getting to the stages of bleeding clutch slave cylinder after the long rebuild of my tf I found that no matter how much I was pumping pedal the fluid was going nowhere, so not having a easy bleed kit to hand I took the trigger from a household cleaning bottle pushed the tube into bleed tube opened bleed nipple and vacuum the system worked a treat. this may have been mentioned before but if it has not then cheap and simple solution.
