Hang-gliding ... a new teaching/learning aid

So here is my latest toy .... sorry ... I mean teaching aid ... as an old(ish) x-physics teacher I just wanted to check to see if Bernouilli's Principle still worked in Second Life.
Apparently it does but the island could become littered with old hang-gliders ... the creater promised they would clean themselves up which they don't always do ... hope the environment people don't find out about this.
When you visit the island then hang-gliding is available for you to play with ... drat ... I mean 'experiment' with ... it's all about enquiry-based learning.
