Jelly Jar Soap Dispenser

This morning I decided my little sink side pump bottle needed an upgrade.  

First I marked a canning jar lid to be fitted with a pump cap.  I turned the pump bottle upside down onto the lid where I wanted my hole for use as a template.  With a fine point sharpie I traced the opening of the pump bottle onto the canning lid.  Next I put the canning lid onto the canning jar and tightened the ring down to stabilize the lid while I worked.  Using a screw driver and hammer I tapped the screw driver through the edge of the hole inside of the marker line.  Remove the canning lid and carefully cut away or pry away at the hole until you have a nice uniform hole. You might try a pair of needle nose pliers and a pair of wire cutters.
The jar lid will rust with use, so consider doing something to seal the raw metal in.
Spray painting your lid or maybe a bit of clear nail polish on your raw edges would likely do the trick. 

Next Using a hack saw cut the plastic bottle just above it's shoulder.  Then trim with a pair of kitchen scissors to neaten it up.  Carefully work the canning lid down over the threads of the Bottle neck and screw the neck into the pump cap taking care not to damage the threads.  Trim the straw on the pump if needed and fill your bottle with soap.  

Enjoy!

Update- If you caulk the pump in with silicone calk above and below the canning lid the dispenser will last a lot longer.
