Solution

Now, when you're going on a hike, and you need some soap to do your dishes, but you don't want to bring the whole 1L bottle of 'Yes'. What do you do?

This is my ingenious solution - you pour it onto your emtpy 'Mary Kay Night Solution' bottle. It has a pump, and a protective cap (so the pump isn't pumping uncontrollably in your bag while hiking). I'm rather proud of my solution to the problem. I wonder what I'll do with my next Night Solution bottle when it is empty in 4-6 months - and what a nice night solution it is!
