Balloon helicopter by Hotoy: Flight and Newtonian forces demo.
incl. GST
Classic party favor that can be used in the science classroom. Good for discussion on Bernoulli or for Newton's Laws. Air is pushed through a channel to the wingtip itself to create the thrust. You might also hear that as the vibrations increase the pitch increases as well (all about frequency... increase the vibrations you the pitch always increases).

Choking hazard: Not suitable for children 3 years and under.
