When I was kid I was fascinated with the future, I could not get enough of it. I remember thinking that I would be living on a moonbase by the time I was thirty (according to the television show SPACE:1999). I was always ordering things out of the back of comic books; magic tricks, jokes, and plans.
One of my few mail order successes was from a company called “Wijit Works” in California. I had ordered he plans for building 4 complete “space crafts” for $3.95. These were the plans for making hovercrafts out of vacuum cleaner motors. I still have the plans to this day, along with two broken vacuums waiting to transformed into personal space crafts.
