I've always thought that a bottle of liquid laundry detergent was poorly designed. Sure it has a handle, and a pour spout, and the convenient cap that doubles as a measure for the soap.
All good features.
The problem is the integrated pour spout.
It keeps you from getting that last bit of soap out of the bottle.
I decided to find out how much and I was amazed that it was equal to the amount needed for a typical "large" load of laundry. (As indicated on the back of the bottle)
Hence this instuctable. It shows you how to get every load you paid for.
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: "V" for Victory.
At the base of the spout, on the side opposite from the handle, cut an upside-down "V" in the bottle with a utility knife. The "legs" of the "V" should be about a half-inch long. My example is a little bigger than that, which is fine.
The pointy part should point toward the top of the bottle.
Now pry out the center of the notch you created.
Step 2: Free the Hostage!
Pour the trapped soap into the cap from the spout you just created.
Step 3: Voila, That Last Load!
Now you can poke the plastic notch back into the bottle and recycle it.
With practice, this process only takes a few seconds. I keep a folding utility knife in the laundry room for this.
