Step 3 

Use a hammer and nail to tap a hole in the lid. Take the nail out when there is a small hole all the way through.

Step 4 

Thread your cotton through the hold in the lid. You many use a threading needle to help if needed.
Tie a loop or knot inside of the bottle lid, to stop the string from coming through.

Screw the lid back on and turn the bottle upside down and place on top of the base.
Fill the base with water (not higher than the bottle cap).
