A Home Lab/Shop For Kids?

sharp-bang writes "When I was growing up, my Dad let my brother and I have the run of his wood shop, and kept up a steady stream of Lego kits, Estes model rockets, chemistry sets, Heathkit projects, and other fun science stuff from the Edmund Scientific catalog, and the rest was history. I'd like to give my kids that kind of experience. If your kids were interested in science, computers, robots, and building stuff, how would you build and outfit a lab/shop for them (and you) to play in?"
