The other day Emma, Leela and I were browsing around the new Heath store in San Francisco when Emma spied this 2.5L Weck jar on a shelf. Emma's been steeping and brewing up a storm these days and the jar looked like a perfect size for her projects. She hesitated, we encouraged; she considered the pros and cons, we emphasized the pros; she spoke of frugality; we reminded her it was under $10. In the end, Emma bought the jar. In fact, she left the store with two. Smart girl, our Emma.
