As a parent of teens I see no harm in trying an experiment using a model and a leaf blower. I think that the lesson in critical thinking and experiment design will prove useful. That said, I believe the device will not live up to claims. This is how we learned there was no such thing as the ether medium in space. I have done some rather counterintuitive things in my life such as roast a marshmallow between my fingers without getting burned and building fairings for mountain bikes immune to side winds.
