Wanna keep your milk fresh longer?
I really think everyone should do the experiment that I did.
The container of milk without CS will turn to a gooey solid in about 3 days. The container of milk with CS will still be liquid, and smell. I if you don't believe me, just try it for yourself!!!
Here's an experiment to try: take one of the leaves of silver, with its paper backing, and weigh this. Then take the silver off the paper backing, this time weighing the paper only. Unless you have a scale that measures in some of the very smallest units you'll get the same weight both times, for the fact is that the thickness of silver leaf is perhaps 20 atoms, so thin as to be measureable in the nanometer range, very little material present. (Note that gold is a little more maleable so may be about 10 atoms thick.)
For leaf metal this thin the big surface area one is seeing is decepetive, with respect to the amount of material that is actually present. Another interesting experiment is to put a little square of the silver (or gold) leaf on ones' hand, then rub with a finger. It's interesting to see that it actually disappears, going right into the pores of the skin.
