Bottles, reusing old bottles is fine but make sure they are cleaned.

Place the bottle cap level on the top of the bottle.
	
Place the metal part of the Knock-on capper over the bottle cap, make sure the cap remains level once you have done this.
	
Hammer the centre of the metal part strongly but not with excessive force.
	
If you feel the need hammer around the edge of the capper.
	
 Remove the knock-on capper, it may feel stuck on so gently move it around and it will come off.
	
Your bottle is now capped!
