I wouldn't shake a jar/container of naoh dissolving in water. The reaction releases heat/vapor, and i think its much safer to just stir it while having it sit in a sink. Naoh dissolves pretty fast in water, and simple stirring will suffice, with out the risk of catastrophic accidents that could end very very bad using sealed containers and shaking.
Just a heads up. Everything else looks good though, good luck.

In a society in which nearly everybody is dominated by somebody else's mind or by a disembodied mind, it becomes increasingly difficult to learn the truth about the activities of governments and corporations, about the quality or value of products, or about the health of one's own place and economy.
In such a society, also, our private economies will depend less upon the private ownership of real, usable property, and more upon property that is institutional and abstract, beyond individual control, such as money, insurance policies, certificates of deposit, stocks, etc. And as our private economies become more abstract, the mutual, free helps and pleasures of family and community life will be supplanted by a kind of displaced citizenship and by commerce with impersonal and self-interested suppliers...
