Step 1: Supplies
1. small bottle with screw-on cork
2. spray mechanism from perfume bottle
3. krazy glue
3. tape (optional)
1. power drill (I used a 3/8'' drill)
2. bench vise (optional)
Step 2: Drill the hole
The bench vise is used to hold the bottle steady for a neatly drilled hole.
Step 3: Apply glue and fit
I decided to fit the mechanism from below because it looks neater and was easier to seal leak proof even under pressure with say....soda.
