Thanks to r414 for the following
Regarding the Ajira Origami Instructions, I found a quite helpful YouTube video explaining how to create the paper ball. The steps are in big part similar with the ones shown on the Ajira website, beside this, after creating the ball and reading the GUM word (if an Ajira ticket printed paper was used), "Mr. G", from the video, transforms the ball into a "Jet Engine". :)
Best wishes,
