Although the bi-cone rolls toward the higher end, its center of mass descends due to the geometry of the rails. This curious construction was first published in 1694 by the noted surveyor William Leybourn to promote “recreation of diverse kinds” towards the “sublime sciences”. Physics fun from three centuries ago!

The clock unit is also quite heavy, weighing in at 2.7kg (6lbs). After some research I believe this clock was produced in China about 50 years ago. Bismuth Diamagnetic Levitation: Element 83 (bismuth) is the most diamagnetic of the elements*. Here a small neodymium magnet is made to float between two 99% pure bismuth 10mm cubes which are held in precise configuration by friction with the parallel walls of the acrylic assembly I made. Diamagnetic substances only have magnetic fields of their own when placed in an external magnetic field from another source- here the tiny cube magnet supplies the field. Diamagnetic fields are pretty weak though so a powerful cylindrical neodymium magnet sits above the cubes and is adjusted to help lift the tiny cube magnet against gravity. *except for a special form of carbon known as pyrolytic graphite. (neodymium, magneticfield, levitation) Ferromagnetic Elements (ferromagnetic, magnets, periodictable) OSM: kinetic art toy- six identical pieces interlock to form this mathematical and mechanical curiosity. Mini-Drinking Bird Heat Engine: this hummingbird sized heat engine is the latest species added to my drinking bird collection. This little guy comes with the traditional top hat and his own plastic goblet- which is the perfect height for a standard drinking bird to share. Cooling by evaporation at the head leads to lower pressure in the top bulb, the pressure in the bottom bulb pushes the dichloromethane fluid up the neck making the bird top heavy and the bird tips over dipping its beak and letting the fluid return to the bottom bulb. The process repeats, and as long as the top stays wet and cooler than the bottom this heat engine will continue to cycle. (thermodynamics, drinkingbird, dippybird, dunkingbird, simpleengine) Jacob's Ladder: high voltage arc rises due to the heat of the plasma created by the current ionizing the air. Here a 7500 volt neon sign transformer produces the high voltage needed to exceed the breakdown voltage of approximately 20kV/cm for air. A must for mad scientists in movies new and old!❗️Please don't attempt this demonstration unless you are fully trained in the safe handling of high voltage. Horizontal Hand Boiler: Amontons’s Law in action as heat from the hand raises the temperature of the dichloromethane vapor the pressure increases in one bulb pushing the red (dyed) liquid through the glass pipe to the other bulb. The process can repeat by switching the hand to the other side, but as both sides heat up the transfer is less vigorous. An inexpensive toy demonstrating gas laws under constant volume and other thermodynamic physics. The d120 Superposition of Spins: an interesting top from Japan that spins around two axes simultaneously. Note the fourfold symmetric pattern made by the graphics- one spin frequency is 4 times faster than the other. 240fps slow motion reveals how the two spins collude to position the heart images.
