If you’ve ever wanted your own HOVERCRAFT, this guy has the plans from the ones he’s built. What I love about this is that this guy I’ve linked to is purportedly a teenager and he says that it only cost him $400 to build his craft, and just the other day I was at a site where this retired aeronautic engineer was making these really COMPLEX (and expensive) hover-type craft that didn’t QUITE work right – LOL. *grin* (Thanks for the link Metafilter.)
