Wind Rider

The Walkalong Glider

This little treasure is popularly known as the walkalong glider and was invented by Tyler MacCready a really long time ago,sometime around 1977 I think.It's as simple as it gets--the picture is self explanatory.
(MacCready was 12 when he made this toy !!)

The design is fairly simple and you can make it yourself(this thing is out of the market by the way...so it's a collector's item now).You'll need zepron/depron and balsam.
