It may be used during science shows, as part of student projects and to<br \/>\nillustrate the parametric resonance in mechanics or even quantum physics, during lectures or<br \/>\nclasses. The parametrically driven LEGO pendulum gains energy in a spectacular way, increasing its<br \/>\namplitude from 10\u00b0 to about 100\u00b0 within a few tens of seconds.
