This video contains:

👉🏻 Vortex II Coin Bank: interplay between potential energy of gravity and conservation of angular momentum- a simulation of a decaying orbit.
👉🏻 Lithophane Color Einstein Portrait: in celebration of the great physicist and his monumental discoveries this portrait is a modern take on the lithophane technique from the 1820s- but updated via modern 3D printing to produce full color images through selective absorption and transmission of light. Traditional lithophanes produced gray tone images by shining light through a translucent substance, initially porcelain, where thicker regions absorb the light and appear dark gray, and thinner regions look light gray. 3D printing allows a new method for producing this art form with amazing detail, where layers of colored plastic, applied in the right sequences and thicknesses, can produce lifelike and artistic results. Another amazing 3D print by Alex L. Kling!
👉🏻 Locomotion Anamorphic Cup & Saucer
👉🏻 Tornado Spheres: two ball bearings welded together can be made to spin up to 2000+ rpm by the Magnus Effect using a stream of air.
👉🏻 "Ghost of Einstein": laser etched version of the hollow face illusion. 👻 Spooky science - the inverted image mask of Einstein appears animated and seems to always be looking in the direction of the viewer.
👉🏻 CMY Platonic Solids: The five famous convex regular polyhedra with thin film coatings, Cyan, Magenta, and Yellow, that allow filtering of the light that enters or leaves particular facets of each acrylic prism. I was struck by the intricate patterns produced in each object’s shadow by the refracted light- especially as the objects rotate.
👉🏻 Chaotic Pendulum Kinetic Art: the motion of this skateboarder is that of a pendulum influenced by magnets in the skateboard and the mirrored base- chaotic motion (in the technical sense) is the result.
👉🏻 Tritium Gas Lamps: mini-glow sticks that emit light for 12+ years- without recharging by a light source. More nuclear physics fun! A phosphor coating shines due to activation by beta radiation from radioactive tritium gas in the vile. Tritium (Hydrogen with two neutrons accompanying the proton in its nucleus) is unstable with a half life of 12.32 years and only emits beta rays (high speed energetic electrons) which are stopped by the glass and plastic- when these electrons impact the Zinc Sulfite (green phosphorescent pigment) they stimulate the green glow just as UV photos would, making the little vile glow constantly and continually. Other pigments can produce glow in other colors, but green seems the brightest.
👉🏻 The Alchemist: this sculpture is cast from diamagnetic Bismuth and features a neodymium cube magnet that levitates- trapped between the hands of the ancient scholar. Diamagnetic substances only have magnetic fields of their own when placed in an external magnetic field from another source- here the cube shaped magnet supplies the field. Diamagnetic fields are pretty weak though so a cylindrical neodymium magnet hangs above the figure and is adjusted to help lift the cube magnet against gravity. Trapped in equilibrium by these magnetic fields, the slightest air currents can send the cube magnet dancing. Although alchemists never succeeded in transmuting lead to gold, in 1981 physicists used the particle accelerator at Berkeley to shoot Carbon nuclei at thin foils of Bismuth- the resulting collisions did produced a tiny amount of Gold atoms! So modern nuclear physics, applied to the element Bismuth, finally accomplished the aspirations of the alchemists.
