We've all tried it.  Adding water to empty shampoo bottle to work up the suds.  Ditto for detergent.  We've all turned the bottles upside down, hoping gravity will do the work. 

And why not? 

What we don't use we waste.  What we waste costs money.  If we get the last drop out we go less often to store to buy replacements.  Manufacturers apparently don't want us to squeeze every drop out; it's almost as if products are designed NOT to release their full volume.

In fact, a study by Consumer Reports investigated how much content was left inside popular items when the packaging design prevented users from extracting all of the product.

  • Toothpaste 1-13%
  • Condiments (ketchup, mustard, etc.) 3-15%
  • Liquid detergent 7-16%
  • Skin lotion 17-25%

So, how do you get the very last drop?  Watch the video and see what happens when a group of local moms show up to The Last Drop Challenge and wrestle with everything from makeup to toothpaste.
