salt of the earth

or salt of the sea, as this is. Biggest was given the task of growing salt crystals. She did it as her teacher told her. It didn't work. Then I grew some too and it did work. I, of course, used a method that is known to work rather than a method that one can politely term "dubious". Mind you, maybe their homework was to fail at growing salt crystals, in which case, she should get 10/10.

As you can tell by the above, I have been watching too much Big Bang Theory again and am living out my inner Sheldon.
