Solar Sculpture: the paths of 5000 magnetic field lines etched into optical quality glass map the complex flow of plasma in the Sun’s outermost atmosphere replicating how the solar corona appeared on Oct 21, 2000. This sculpture is based on a sophisticated computer model from a group of research scientists at the Lockheed Martin Solar and Astrophysics Laboratory, and the rendering contains 300,000 etched points to create the image. A map of our wonderful and complex star that can be held in the palm of your hand.
Well engineered brass spinning toys by SiriusEnigmas

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!

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.

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.

From Etsy: BUY NOW: Missing Square Puzzle
Matsuyama’s Paradox: dissect a large square in to four equal quadrilaterals, rotate and reassemble- to find a small square is missing! Where did the additional area come from? Fun math involved in the design of this puzzle, which illustrates how the concept of area can often challenge our intuitions. Swipe to compare the two assemblies. A precision crafted puzzle by Jeux Efcé game shop. Wikipedia has good details: Missing square puzzle.

Warped Spiral Kinetic Art: a slight breeze will set this stainless steel sculpture into graceful and mesmerizing action. When spinning the rotation creates translational motion along the vertical- and each helix in this version has a slight asymmetry that adds to the complexity of the perceived motion.

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,

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.

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.

From Etsy: BUY NOW Four Marble Puzzle
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.
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.

From Etsy: BUY NOW: Lissajous Roller Illusion
Lissajous Roller: when viewing this 3D printed object from the side one sees a projection of a 3:2 Lissajous curve, but the object is actually cylindrical in frame and can roll towards or away from the viewer. When in motion a “dual axis illusion” is produced where the object appears to be rotating about a vertical axis. Invented by Bill Gosper and produced by Pyrigan & Co.

Available on Etsy: BUY NOW Motion Ferrofluid Sculpture
Colored Ferrofluid Display Cells: spectacular metallic blue, gold, and black display cells by czferro - colloidal ferromagnetic liquids in a specially prepared water-alcohol suspension. Curious behavior results from the interplay between magnetic force and surface tension. The gold and blue coloring appears to be from a thin coating at the boundary between the ferrofluid and the suspension liquid. Still exploring the details of the coloring and the specific makeup of the clear suspension fluid - both trade secrets it seems.
