Picture of Foam Pump Mason Jar Soap Dispenser
Create your own foam pump mason jar soap dispenser from material that you may already have in your home.

Did you know that the foam soap that you buy at the store contains mostly water and that it is actually the pump itself that creates the majority of the foam?  Save yourself some money by diluting 6 parts water to 1 part of your favorite liquid soap.  

Think about it...only 2 oz of liquid soap will fill your pint sized widemouth mason jar.

Step 1: What you are going to need

Picture of What you are going to need
Use of hardware is required for this instructable and should not be attempted by anyone who is not familiar with the tools used for this project.

* Wide mouth mason jar with lid, band and jar
*  Clean foam pump with the bottle (you can reuse one that you already have, just clean it out)
*  Drill
*  Bi-metal hole saw (most likely 1 1/2 or 1 3/4)
*  A press to hold the lids in place
*  Lubricating oil for saw
*  Epoxy, water sealant, or any other waterproof glue
*  Metal file
*  Junior hacksaw
*  Permanent marker
*  Gloves and goggles

Okay, you ready?
You got this, you can do it :)

Step 2: Measure it

Picture of Measure it
First you will want to measure the circumference of the circle that you will be cutting by comparing it to the bottle you will be using.  Make sure that the hole will pass the threading without going all the way thru the outside bottle

Step 3: Mark it

Mark the center of the lid with your pen.  No need to make it fancy, unless you wanna, just take note of the center.

Step 4: Line it up

Picture of Line it up
We rigged up some boards that stand off the floor to hold the lid in place and keep it from moving. Use a press and make sure that the lid is secure and tight because, when the drill comes down it is going to want to slide out from under you and you need to make sure that it will not slide out from under ya.

Thanks, Flavrt :)

Agreed! The soap that is sold in mainstream retail is full of different types of chemicals, so much that they can no longer be considered "soap" They have labels such as liquids, gels, detergent etc.

Figured out a few years back about the soap industry and how they were trying to one us over by making us think that it was the soap that was causing it to foam so much when in truth, it is just the pump forcing air into the water and soap mix. (Think like what a sponge does when you squeeze it in soapy water)

It's a matter of preference on the dilution rate that you would like to use. Found that anywhere between 1/3 ratio and 1/10 worked with the pump. Just keep in mind that if the mix is too thick it will clog the pump and if it is too thin, it can wear out the lubrication in the spring.  We give the ratio of 1/6 for the soap that we sell.

Very good. You scooped me.

We like foaming hand soap, but it is crazy expensive. And they warn that the dispenser will not work right with ordinary liquid soap. Ha, because it is so diluted. I've been mixing 1 part soap to 3 parts water, which works fine.

Best of luck with OSSC. I hope you find a big market for unscented soap. Who wants to work with vegetables with chemical fragrance permeating their hands?
