Rhombic Blocks Mathematical Puzzle: There are 9 possible ways three rhombuses can be joined together along a common edge, and similar to pentominoes, these 9 tri-rhombs can tile a polyhedron, in this case a hexagon. There are 14 solutions to this puzzle, and one where no same-colored pieces touch. A beautiful math discovery by puzzle master Stuart Coffin.

Logarithmic Spiral Gears: an extreme example of non-circular gear sets. This set is based on the famous Fibonacci spiral and evokes the cross section of nautilus shell with internal chambers. If one gear of this set is turned at constant speed, the other will turn with an varying speed. A laser cut based on 3D prints of Misha Tikh and the research of Balint et al. 

Magnetic Tip Spinning Top

Magnetic Tip Spinning Top: the top stays on the perimeter of the steel plate spiral- but since the top is more massive, the spiral moves with curious motion. This kinetic art toy takes advantage of Newton's 3rd law and rotational kinetic energy.

Kaleidoscope Symmetry Physics: Two adjacent mirrors form the repeating image of a kaleidoscope, but the shape of the image is determined by the angle between the mirrors. This principle is demonstrated with three different symmetrical patterns using this beautiful set of precision teleidoscopes- angles of 36° (blue tube), 30° (green tube), and 22.5° (red tube), creating mandala stars with 5, 6, and 8 points. The angle for any symmetric star pattern of n points is just 180°/n. A teleidoscope is a kaleidoscope but with a lens on the end, such that the kaleidoscopic image is formed by whatever is put in front of it. Here the complex motion of a Gyrobi toy is used as the observation object. 

Impossible Caged Golf Ball 

Some nice versions of this impossible object available here:

Impossible Caged Golf Ball: Here a regular off-the-shelf golf ball is somehow trapped within a cage made from a solid piece of hardwood walnut. Neither the ball nor the wood were cut or glued in the fabrication process. The puzzle aspect is to consider how this object was produced (I have some theories- but I do not know the secrets of this artist).

Widmanstatten Pattern

Widmanstatten Pattern: this slice of Gibeon Meteorite has been etched with mild acid to show these nickel-iron crystalline structures that are only found in meteorites. Widmanstatten patterns from nickel-iron can not be produced in the lab or in any factory- the structure only forms if the metal cools at a rate of 100 degrees per million years! 


Fine Wood Tippe-Top

Handmade flip over tops available here:

Wham-O Magic Window

Fine Wood Tippe-Top: spinning things often have surprising physics! This lathe worked version of the famous flip-over top is made of ebony and wood from the pink ivory tree. Friction with the mirror provides a torque that acts on the existing angular momentum of the top to flip it over. The top will stay flipped until the spin rate slows down enough to where its center of mass pulls it back to the resting position. 

Vortex Marble

A number of artists now offer vortex marble art on Etsy 
From Etsy: BUY NOW Vortex Marbles 

Note: this site contains affiliate links for which I may be compensated

Vortex Marble: glass art intersects with the physics of optics in this lampwork art form invented by Kevin O’Grady circa 1994- and this marble bears his signature mark on the back. The clear glass face on these marbles acts as a convex lens giving the illusion that the spiral goes deeper than the diameter of the marble. Different kinds of dichroic glass (doped with thin layers of metals and oxides) is mixed in to the borosilicate marble to create the intense colors.

A nice version of this tensegrity icosohedron is sold as a toy for tiny tots:

I constructed this version by referring to the images and descriptions of tensegity on Wikipedia 

Tension Integrity Icosohedron: Six brass struts float isolated from each other but held in a stable configuration by a net of 24 connecting cables. I made this sculpture using hollow brass tubes and weaving through them a single strand of fishing line, which is connected after passing through each tube exactly four times. This configuration of three sets of parallel struts forms a Jessen’s icosahedron under tension, and was invented by the famous architect Buckminster Fuller in 1949.


Impossible Trapped 8-Ball

From Etsy: BUY NOW: Trapped 8-Ball

Trapped 8-Ball: one more addition to my “impossible object”collection- a solid wooden frame contains an 8-ball which is too large to fit through any of the holes. The puzzle aspect is to consider how the ball was somehow inserted (as usual I personally have some theories- but I do not know the secrets of this artist). I can tell you with high certainty that the frame was fabricated from a single piece of wood, and once made, never cut or glued in anyway. A creation by artist/maker Troy Hawkins. 

 

 

 

Impossible Bottle with Arrow

Impossible Bottle with Arrow Sculpture Puzzle: a new seemingly impossible object in my collection- Created with clever engineering, this “impossible” syrup bottle contains a wooden arrow that should not fit through its neck. The wood of the arrow is notably one uncut piece, and yet a metal washer is also somehow trapped on the shaft of the arrow. The puzzle aspect is to consider how the bottle was produced (I personally have some theories- but I do not know the secrets of this artist). I can tell you with high certainty that the bottle was never cut or altered in anyway, and it was not somehow formed around the objects. This bottle by Brad Byers is an expertly crated example of the impossible object genre.

Impossible Frame in Bottle: another seemingly impossible object in my collection from craftsman/artist Grant Wicks AKA the Bottleologist. A framed photo complete with all hardware somehow assembled within a Fannys Bay Whisky bottle- a uniquely square bottle. More- the photo is a recursive Droste Effect image of the bottle itself. The puzzle aspect is to consider how the bottle was produced (I personally have some theories- but I do not know the secrets of this artist). I can tell you with high certainty that the bottle was never cut or altered in anyway, and it was not somehow formed around the frame. 


Big Dipper 3D Sculpture

From Etsy: BUY NOW: Big Dipper 3D Sculpture

Asterism in a Box: Swarovski pearls, suspended by nylon lines in a specific spatial orientation, represent seven well known stars in the Northern night sky. The pearls in this sculpture show the actual 3D configuration of the stars that make up the Big Dipper! Only from one particular point of view- that of our sun- do they look like the "dipper", and this sculpture shows what this cluster of stars would look like from other “near by” star systems in our galaxy. Note that large pearl in the bottom right represents the star Dubhe, a blue giant some 326 times brighter than the sun and the farthest of the Dipper stars at 123 lightyears away. The rest of the stars range in distance from 58 to 101 lightyears, as measured from Hipparcos satellite telescope mission data. From artist Caroline Bowen of Hypotenuse Studios.
