As impressive as some of the backyard rollercoasters are, I don’t think I’d want one for myself. Due to inherent limitations of physics rollercoasters are one type of ride that just doesn’t scale down very well. A small rollercoaster will always mean a short ride time, unlike, for example, a miniature steam train or merry-go-round. This one lasts maybe
8 seconds, so I think my kids and I would get bored of it pretty quickly. But I’m still glad that somebody is out there building these things, because the YouTube videos are always fun.
