I knew of the “Evil Mad Scientist Laboratories” website because I saw the “How to make the simplest electric motor” link on Reddit (which, by the way, is a very effective, very entertaining time sinker guaranteed to suck years from your life.)

If you like the Evil Mad Scientist site, you might also find Science Toys and The Science Toy Maker interesting also. I think these websites will be very handy when Titus and Tatia start on their apprenticeship in mastering space and time. After all, inventors of warp drives need to start somewhere.
