Vas ist das

A pretty neat-o website, that lists about five ''What is it?'' items of the week, from various crafts and trades (plumbing, basketry, cooking, woodworking, surveying, medical...).  Later, they update the blog entry (at the bottom; scroll down) with the answers.

Good for weekly competitions with co-workers; learning about technological history; or just gaining some ''common knowledge''.

They've been doing it for a while -- so they have a lovely deep archive.  The photo I've posted here is from set #435.
