Spinning Liquid Pen: two immiscible fluids (three if you count the air bubble) are sorted under gravity by density with the densest on the bottom and the lightest on top. When the container is rotated, the boundary between the layers forms a parabola due to the added influence of centripetal acceleration as seen here in 240 fps slow motion. The plastic dolphin has a density between that of the two liquids so it stays at the boundary layer. A rather silly toy- but so much physics to explore here!

Radiometers: three “light mills” from my growing collection of radiometers (now at 23 so far), including a double with two spinning flys in the same partial vacuum volume. Here the initial light is from a LED, and then a halogen incandescent bulb is turned on which activates the motion. This device goes way back, invented in 1873 by the famous chemist Sir William Crookes when he was investigating partial vacuum environments. Light heats up the “vanes” which then heat up the very thin gas left in the partial vacuum within the bulb- the black side of the vane is hotter than the silver side and any gas molecule that comes into contact with it flies off at a faster speed imparting impulse to the rotor.

Mirror Rattleback Pair

The amazing work of Emmanuel Péluchon can be purchased here:

Other rattlebacks variations found here- check them out: physicsfun rattlebacks

Enantiomorphic Rattlebacks: due to mirror reflection construction, one prefers to spin counter clockwise the other prefers clockwise. This behavior is related to an asymmetry in weight along the left/right symmetry axis of these beautifully crafted objects- the dark wood is Apple which has twice the density of the light colored Basswood(Linden). This asymmetry in weight induces an instability, quite like the vibrations that arise from an unbalanced tire, that transfers the rotational energy to the intermediate rocking vibrations. This amazing set was made by Emmanuel Péluchon, fine woodworker and artist. 

Zulu Telephone Wire Bowl

Geometric Weaving: this Zulu telephone wire bowl, made in the traditions of South Africa, features a brilliant spiral pattern. The bright colors come from weaving strands of colored wires- the kind used to connect phones throughout buildings. This particular pattern inspired using a rotating base to display this bowl as kinetic sculpture.

100 Carat Diamond Timer: a classic one minute timer glass but filled with tiny diamonds! Another novel creation that just arrived in my @thecuriositybox — ideal timing for a New Years day post. Actual diamonds but synthetic from a process called chemical vapor deposition, think less gemstone and more industrial- such as those used in diamond tipped saw blades used to cut gemstones. Yellow gold in color due to nitrogen impurities that facilitate the carbon atoms to join into the diamond lattice structure. These tiny crystals seem to be quite elastic and they rebound energetically as they hit glass below.

Cubic Holoscope: a cube of mirrors creates a geometric universe within. A type of kaleidoscope based on truncated Platonic solids by artist Gary Allison @holoscope2000. Through the symmetry of the reflections, these triangles appear as an infinite array of repeating stellated octahedrons. Each holoscope has stained glass on the exterior and front surface mirrors on the inside which create the amazing and seemingly impossible spaces. 

Polariscope and Snowflake Decor

The needed snowflake decoratons and polarizing film are affordably priced here:

Polariscope Holiday Decor: while wearing my polarizing sunglasses I happened to notice psychedelic and fractal like colors appearing within these snowflake decorations, inspiring further exploration and production of this display. What’s going on? Polarized light revealing the hidden rainbows due to internal stresses imposed on polymer materials such as these snowflake ornaments of polystyrene, a technique used to model stress distribution patterns in engineering. Place the polymer samples between two linear polarizer filters and the internal stresses created by the molding process during manufacturing produce colors through birefringence due to photoelasticity.

Tunnelscope: Circular Mirror Kaleidoscope

Tunnelscope kaleidoscopes of many designs available here:

From Etsy: BUY NOW: Tunnelscopes

Tunnelscope Circular Reflection Kaleidoscope: in this novel design a straight length of transparent acrylic rod provides the reflective surface, and two wheels filled with resin and interesting shapes of colored glass can each be turned separately to produce a flow of psychedelic patterns. The physics of refraction and total internal reflection allows for multiple reflections of the images down this light pipe “tunnel”, in essence providing a near perfect circular mirror design. A creation of kaleidoscope innovator and artist Roy Cohen, and made from polished brass, cast acrylic, and colored glass.

Jacob’s Ladder Image Flip: this Curiosity Box Inq the Octopus themed toy flips between two famous aperiodic tilings- Penrose rhombs on one side and the recently discovered einstein hat on the other. The earliest description of the ribbon hinged “Jacob’s Ladder” mechanism that creates this kinetic illusion of cascading blocks dates back to a magazine article from Scientific American magazine in 1889.

Magnetic Equilibrium Pen: a weighty and elegant wooden writing pen dances and stands up on its tip when released, trapped against gravity by magnetic fields. Magnetic viewing film reveals the shape of the field from the strong neodymium magnet in the base, and that of the magnets embedded in the pen. The strength and geometry of these fields allows the pen to stand on its tip even when the base is tilted! Some fantastic physics for the desk top.

Chaotic Triple Pendulum: the intricate dance of chaotic motion from an assembly of three physical pendulums, shown here (partly) in 120 fps slow motion, where the energy imparted to the system moves back and forth between the potential energy of gravity to the kinetic energy of motion until eventually damped out via friction. Chaotic motion is characterized by extreme sensitivity to initial starting conditions, tiny differences in how the system is released leads to dramatically different outcomes each time. A second of many configurations possible with this extraordinary design by Kontax Engineering Ltd.
