Penrose Tiling Puzzle: a challenging puzzle with pieces that come in only two shapes. The physicist and mathematician, Sir Roger Penrose, famous for his contributions to General Relativity, also discovered tessellations (tilings) that are aperiodic even though the two tile types are regularly shaped polygons. If one tries to shift a part of a Penrose tiling, the shifted part will not align or match up with any other part of the same tiling- all the way out to infinity! This puzzle, entitled “Perplexing Poultry”, uses polygons modified into crazy looking birds such that the tiles can only connect in specific ways to ensure the non-repetitive nature of the Penrose tiling structure. Shown here is one way these two tile types will fill the plane.

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.

Four Marble Puzzle: physics brain teaser- move all four marbles to their corner locations simultaneously. Each slot slopes down towards the center such that the marbles tend to stay at the center- so, how would one get them to roll outward at the same time? The solution to this puzzle (like others featured here) relies on some fun basic physics principles. Answer below and swipe to reveal solution. A beautiful and well-made puzzle from Creative Crafthouse.

Aquarius Fountain Lamp

Aquarius Fountain Lamp: an oscillating stream of water is illuminated by strobe lights to reveal underlying structures and forms typically hidden from our vision. With the help of programmable micro-controllers, strips of addressable RBG LEDs are made to flash in sequences that make the water stream appear to move upwards, change colors, and split into multiple braided streams. Art meets physics and clever technology in this wonderful creation by computer engineer Stephen Co. With sincere appreciation to Stephen @northerncircuits for sending me one of his hand crafted high tech fountains.

From Etsy: BUY NOW Diamagnetic Levitation Sculptures 

Eclipse: A diamagnetic levitation sculpture by Element83. Cast from diamagnetic Bismuth, a golden spherical neodymium magnet levitates trapped in a tunnel within the metal. Diamagnetic substances only have magnetic fields of their own when placed in an external magnetic field from another source- here the sphere magnet supplies the field. Diamagnetic fields are pretty weak though so a powerful cube neodymium magnet sits above the tunnel and is adjusted to help lift the sphere magnet against gravity. Trapped in equilibrium by these fields, any other magnet brought near will change the balance. ?Another amazing creation by Ernie McElhannon.

Gyrobi Kinetic Toy 

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.

From Etsy: BUY NOW Double Chaotic Pendulum 

Mini Double Pendulum: the intricate dance of chaotic motion from a simple assembly of two physical pendulums (one attached to the end of the other) with the energy of the system moving frenetically back and forth between the potential energy of gravity to the kinetic energy of motion. Chaotic motion (shown here in 240 fps slow 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. This well made precision bearing double pendulum is made by Doug Cvelbar.

Tesla’s Egg of Columbus: a copper ellipsoid egg (PhiTOP) mysteriously spins and stands upright in this modern version of Tesla’s famous demonstration from the 1893 World’s Fair in Chicago that first showcased the principles behind wireless power transfer and his AC induction motor. Rotating magnetic fields from under the wooden platform induce electric eddy currents to flow in the copper PhiTOP- these currents then create their own magnetic field which oppose the initial fields underneath and pushes the PhiTOP to spin. This version differs from Tesla’s in that the rotating magnetic fields are created by, well, a pair of rotating neodymium magnets (revealed by lifting the top platform in this model). Credit to astrophysicist Kenneth Brecher, the creator of the PhiTOP, and this unique means of using a common lab magnetic stirrer to create the induced currents. Finally, the ellipsoid top stands up vertically (when spun with sufficient rotational velocity) due to physics similar to that of the tippe-top. 

Impossible Bottle Sculpture Puzzle

Mr. Evans makes a variety of amazing impossible bottle sculptures:

Nice Impossible bottles are often available on Etsy: 
From Etsy: BUY NOW Impossible Bottles

Impossible Bottle Sculpture Puzzle: seemingly impossible, but created with clever engineering, this “impossible” bottle contains a padlock and full deck of cards still in the wrapper (a cut out in the side of the box reveals that all the cards are inside). 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 Phil Evans is one of the best I’ve seen.
