Our young testers did not embrace Gliders by Design , probably because it is not as intuitive as folding a sheet of paper and tossing it into the air. Teenagers and even adults who are willing to invest a little time are more likely to find this interesting, and appreciate its value. No problems were encountered using Gliders by Design on our test computers. However, it wasn't obvious exactly which folder should be opened first. Shuffling back and forth between folders and files with helpful design details when trying to construct a glider was awkward.
Motivated teenagers can use it without adult supervision.
Concepts are clearly explained, however many kids may not have the perseverance to get that far. Even younger children could appreciate and understand the variables of flight when presented in this manner. It would be a fantastic science project. But lets face it, even if you only absorb a fraction of the concepts explained, it would be pretty gratifying to build a glider that didn't crash on impact on its maiden flight.
