A tweet by @ChocoLinkage (https://twitter.com/ChocoLinkage/status/1174513390514921473) showed a teardrop shape being drawn by a mechanical linkage. I've tried to recreate it in Lego. Only one half works because it is difficult to avoid parts having to pass through each other.

An embodiment of "Sarrus linkage 1". Two planes of two planar slider-crank mechanisms are not necessary to be perpendicular to each other. It is enough that they are not parallel.

The physically more accurate problem of damped harmonic motion.
From playlist Differential Equations
In this video i demonstrate Underdamped, Critically Damped, and Overdamped. I use ruler magnets and aluminum (pendulum). Magnet moves near aluminum and Foucault currents stop smooth the pendulum.

AWESOME SUPERCONDUCTOR LEVITATION!!!
A quantum levitator it's a circular track of magnets above which a razor-thin disc magically levitates, seeming to defy the laws of physics. The key to the levitator is the disc, which is made of superconducting material sandwiched between layers of gold and sapphire crystal. A piece of fo
