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.

Nixie Tube Clocks
Nixie Tube Clock V2: long before there were 7 segment LED displays there was the Nixie- cold cathode tubes with a wire mesh and 10 cathodes shaped in the form of numerals 0-9 that illuminate through neon glow discharge. The “Numeric Indicator eXperimental 1” or NIX 1 was introduced in 1955 by Burroughs Corporation and manufactured until the 1990s. This clock uses modern electronics to power Russian versions called the ИH-12A where the numbers are stacked so the front symbols obscure each lighted cathode minimally: from back to front 162750483.

From Etsy: BUY NOW: Kinetic Magnets Illusion Spinner
Kinetic Magnet Illusion Disk: explore amazing phenomena from the physics and psychophysics of vision- give this disk a spin and the imparted angular momentum (along with precision bearings) allows for sustained rotation and a changing visual experience. The spiral design converts rotational motion to radial motion inward and outward, and the dots on the image seem to dance and blur as the flicker fusion frequency threshold of our vision is exceeded. Looks amazing in person, and on video additional effects can be made depending on selected frame rate. One of many designs available from artist Dmity Shytko.
Choose from black, blue, or gold ferrofluid:
Available on Etsy: BUY NOW Nano Tree Ferrofluid Sculpture
Ferrofluid Magnetic Tree Sculpture: the 'Nano Tree' by Concept Zero designs using gold colored ferrofluid which can be manipulated with a handheld magnet. The spiky structure is due to the balance between the forces from the focused magnetic fields (from a neodymium magnet in the base connected to an iron rich bolt) and the forces from liquid surface tension on the colloidal ferromagnetic liquid.

Automata Kinetic Art by Newstead
Pegasus Automaton: Turn a crank and this metal pterippus takes flight using simple mechanisms in what mechanical engineers call a closed kinematic chain. In his elegantly crafted automata, artist Keith Newstead uses a crank connected to linkages with multiple joints to translate rotational motion to choreographed linear and oscillatory motions.
These laser cut hardwood geckos are available here:
From Etsy: BUY NOW Tessellating Geckos
Tessellating Geckos: MC Escher inspired lizard cutouts interlock precisely to tile a surface with no overlaps or gaps. Laser cut from maple, walnut, and cherry wood by maker/artist Craig Caesar and inspired by MC Escher’s “Study of Regular Division of a Plane with Reptiles” 1939. G4G week: Martin Gardner wrote about the art and math of Escher in 1961- which helped create the popularity that his work has experienced ever since.

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. ?Thanks to Leif Colson of Colorado Scopes for this set!

Hybrid Kaleidoscope: the beautiful symmetry of multiple reflections in a unique design- part teleidoscope (image from spherical lens) and part kaleidoscope (image from colorful objects in viewing cell). Invented by the famous Scottish physicist Sir David Brewster (1781-1868), the kaleidoscope is an ultimate physics toy and entire field of artistic endeavor. This vintage find is labeled “C. Bennett Scopes for AKAG 1984”.

Professor Brecher has a limited supply of these "golden" (brass) versions of this top available on Etsy
From Etsy: BUY NOW PhiTOP in Brass
The ΦTop - Golden Version: spinning things have surprising physics! This unique top is made of solid brass in the shape of a prolate elIipsoid- and the name of the top is derived from the following design requirement: the ratio of the semi minor (short) axis to the semi major (long) axis is made equal to the mathematical constant the golden ratio φ (phi). Invented by astrophysicist Kenneth Brecher, this top stands up vertically (when spun with sufficient rotational velocity) due to physics similar to that of the tippe-top. The concave mirror keeps the top from wandering off and the glass surface has minimal friction allowing the top to spin for a long time- this video shows various stages of 8 minutes of total spin time.

Circa 1981, Physicists transmute Bismuth to Gold: Particle accelerators make possible the ancient alchemist’s dream—but at a steep cost
The Alchemist: cast from diamagnetic Bismuth, a neodymium cube magnet 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. ?Another amazing creation by Ernie McElhannon.

BUY NOW Hydrophobic Water Maze
Hydrophobic Water Maze: a superhydrophobic coating allows this dynamic puzzle to use a drop of water as the "pinball", which can split into multiple smaller drops and recombine along the way. The wood surface is treated with silica nano-coating that makes water roll off- a condition sometimes referred to as the Lotus effect because leaves of the Lotus plant have this property.
This puzzle was produced and sold in the 1990s.

A nice basic version of Penrose Tilings is available here:
From Etsy: BUY NOW Penrose Tiles
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.
