Building a shaduf

Since we read chapter 1 of SOTW, we've been talking a lot about ancient farming techniques, so today Elf and I built a miniature shaduf in the backyard, from odds and ends we had laying around. Best of all, it worked, so both kids got a really good idea of this simple farm machine.
