More of this artform here: Vortex Marbles

Vortex Pendant Marble: A radiant spiraling illusion as a necklace by artist Karmen Trebolo- where glass art intersects with the physics of optics such that the clear glass face on these spheres acts as a convex lens giving the illusion that the spiral goes deeper than the diameter of the glass. Different kinds of dichroic glass (doped with thin layers of metals and oxides) is mixed in to the borosilicate sphere to create the intense colors. The vortex illusion lampwork art form was invented by Kevin O’Grady circa 1994- swipe to see one of his marbles that bears his signature mark on the back.

 

Tensegrity for the Desk

From Etsy: BUY NOW: Tensegrity Sculpture

Tensegrity for the Desk: an elegant, and stackable, desk toy version of this popular tensegrity configuration by maker/designer Micah Murdoch. Constructed from poplar wood, the design assembles easily with clever ball and socket connectors at the ends of the nylon support lines (3 long, 1 short). Stacking them seems to only increase the illusion of floating with the subtle way these structures defy gravity. Another fun configuration of tensegrity concept, invented by Kenneth Snelson and made famous by the architect Buckminster Fuller in 1949.


Impossible Nail

Nice versions are curretnly available from Etsy:

From Etsy: BUY NOW: Impossible Nail

Impossible Nail: An eighteen-penny nail driven through the inner notches of a solid piece of wood. The wood was notched and the nail added- no glue used or cuts made, and the nail is solid and in one piece. Not impossible, but creating this does depend on the use of some amazing physical properties of wood. I won’t reveal the method here but a quick search on YouTube produces a few how-to videos showing the process. 

Chil Balance Sculpture

This elegant design comes ready to assemble in your choice of four colors:

From Etsy: BUY NOW: Chil Balance Bird

Chil Balance Sculpture: the mass and orientation of the wings creates a center of mass below this sleek bird's beak- making a system that will rotate and oscillate about a stable equilibrium. No magnets! An elegant sculpture by artist Bin Xu of BinDesign that comes ready to assemble complete with stand,

Bismuth Maglev Rod

Click here to see other diamagnetic toys and scuptures 

Bismuth Maglev Rod: Small magnets are trapped, suspended and floating, within the notch of a rod cast from the diamagnetic metal bismuth. Diamagnetic substances only have magnetic fields of their own when placed in an external magnetic field from another source- here the small floating magnet supplies the external field. Diamagnetic fields are pretty weak though, so a powerful neodymium magnet sits above the gap on the top of the rod, and its height is adjusted to help lift the small magnet against gravity. Another amazing creation by Ernie McElhannon of Element83.


Moon Globe with Raised Relief

Get this incredible globe here:

From Etsy: BUY NOW: Terrainian Space Globes

Moon Globe with Raised Relief: explore our Moon in your own hands with this incredibly detailed lunar globe where all surface features have been rendered in 3D topographic relief- where the mountains and craters actually cast shadows. Note how the selenography of the far side is radically different from the familiar near side- with no flat maria plains- and craters stacked upon more craters. Humanity has only known what the far side looks like since 1959 when the Soviet spacecraft Luna 3 took the first photos, and the Moon’s full map was completed via NASA’s Clementine orbiter in 1995- the data upon which this globe was made. Shown also are the six Apollo landing sites where humans have left footprints in the lunar regolith. This globe is made by Jeff Hobbs of Terrainian Space Globes by a process of precision CNC machining and cold casting techniques, complete with space-age look base stand.

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.


The PiTOP

Well engineered brass spinning toys by SiriusEnigmas

From Etsy: BUY NOW: The PiTOP

From Etsy: BUY NOW: The PhiTOP 

The PiTOP: this beautiful brass cylinder has a radius of 1 inch, a height of 1/π inches, and displays the first 109 digits of π on its face. Spin this disk (best with sound on) and it will demonstrate some very interesting physics involving energy transfer and conservation of angular momentum. The edges of the cylinder are rounded and engineered to exhibit an optimum motion of a “spolling” coin, a motion that combines spinning and rolling (closeup shown in 240fps). As the disk’s angle of inclination decreases the speed of the rolling increases dramatically until the contact point with the mirror is moving in excess of 200mph. From the mind of physicist Ken Brecher, inventor of the PhiTOP (swipe for video). Note also that with the specified height, that the volume of this cylinder is exactly 1 cubic inch! 

Impossible Bolt

Only available from these aritist/craftsmen: 

From Etsy: BUY NOW: Impossible Bolt & Nuts

Impossible Bolt: one nut threads on clockwise as normal- the other threads on counterclockwise on the same bolt! Not impossible- but carefully engineered and machined. Swipe for partial hint on mechanism. This puzzling curiosity was inverted by Scott Eliott and machined in solid brass by puzzle crafters Steve Nicholls and Ali Morris of TwoBrassMonkeys.

Sphere Sticks Geometric Puzzle

Get this affordable and amazing puzzle here:

From Etsy: BUY NOW: Sphere Sticks

Sphere Sticks Puzzle: 30 identical wood pieces, each with two notches as shown, can create 12 interlocking pentagons in a perfect symmetry- look carefully and you can see that each rod is in an identical configuration with the 4 others that connect with it. Precision cut notches on the rods allow them to interlock with elastic tension such that vector sum of the 4 forces sum to zero in this tensegrity type equilibrium. The dodecahedron, with its 30 edges and 12 sides, is the basis of this puzzle sculpture.

From Etsy: BUY NOW: The PhiTOP

From Etsy: BUY NOW: The eTOP

From Etsy: BUY NOW: The PiTOP

The iTOP: inverting spinning disk- the equilibrium state for a spinning thing is often different from that of the same object when stationary. When spun, the iTOP almost instantly inverts to raise its center of mass (shown in slow motion because it happens so fast). However, when the rotation speed decreases to a certain rate the system becomes unstable (shown again in slow motion) and flips again before going into a rolling/spinning motion like a coin. This top completes the set of four spin tops by astrophysicist Kenneth Brecher, all made of polished brass and themed on a mathematical constant. Swipe to see a demonstration of each: iTOP (square-root of -1), PhiTOP (golden ratio, φ), eTOP (base of the natural log), and the PiTOP (C/D of a circle, π).

Another wonderful design by artist Bin Xu.

Butterfly Mendocino Motor

Get this elegant motor here:

From Etsy: BUY NOW: Butterfly Medocino Motor

Butterfly Mendocino Motor: the simplest (and very elegant) version of this motor with only two photovoltaic cells mounted with care to ensure precision balance. This motor will spin quietly to high RPMs on any sunlit windowsill. In this model made by Semyon Nazarov of SolarWindRU, each of the two photovoltaic solar cells is connected to a coil of copper wire under the opposing solar cell. When the rotor is lit from above the top solar cell provides electric current to the coil in the bottom position which becomes a temporary electromagnet that pushes against the permanent magnet in the base propelling the rotor to rotate. As the rotor turns, the coil that moves into the bottom position is likewise energized by the solar cell currently at the top- one can say the light commutates this motor. 2D magnetic levitation is provided by permanent magnets where an acrylic plate constrains the third dimension, and makes for a nice bearing surface for minimal friction. Invented in the 1960s by Daryl Chapin of Bell Labs and popularized by Larry Springs of Mendocino CA

Neon Plasma Glassware

Sold individually, or as a set, here:

From Etsy: BUY NOW: Plasma Glassware and Excitation Base

Neon Plasma Glassware: serve up a platter of plasma! These double walled glass mugs glow orange and blue from the excitation spectrum of neon gas at low pressure. The base contains a high frequency transformer (Tesla coil) that generates high voltage electric fields (but at very low current) which excites the neon to glow, and also serves as a display platter. The inner volume of each glass varies in thickness which leads to variations in heat and pressure which in turn produces different excitations (orange and blue) of the neon gas in patterns that dance and dazzle the eye. An upcoming video will show these filled with beverages. Stunningly beautiful kinetic art and tech by creator Zerg Dragonymous.
