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.
From Etsy: BUY NOW Ferrofluid Lava Lamp
Ferrofluid Interactive Lava Lamp: special ferrofluid infused wax allows manipulation of the blobs of “lava” with a weak magnet, adding an interactive element to the already mesmerizing physics of convective heat flow, Archimedes principle, and immiscible liquids. Love the atomic rocket theme on this updated version of the 1960s classic physics toy.

Nixie Tube Clocks
Nixie Tube Clock: 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-19A where the numbers are stacked so the front symbols obscure each lighted cathode minimally: from back to front 1320984756.

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: 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.
A nice version is curretnly available from this Etsy craft store:
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.

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.
Another wonderful desing by BinDesign- get one here in black or natural wood:
From Etsy: BUY NOW: Bin Design Balancer Puzzle
Balance Stacking Sculpture: a series of torques in unstable equilibrium complete this Calder-esque structure. As each component is added its weighted end balances all the others before it, with the initial small piece weighing about a gram or so. Remove the end piece and the whole structure comes down. Another wonderful design by artist Bin Xu.

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.
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,

From Etsy: BUY NOW Kyle's Kinetics
Surf's Up!: Another gravity defying creation by Kyle Auga, this time a well-balanced stainless steel surfer that carves waves in the air for over 10 minutes on one push! The surfer has the curious motion of a 3D physical pendulum- a complex motion which can be broken down into oscillations along two dimensions and rotation about the point of contact. The stick figure plus counterweights and bar structure is designed such that its center of mass is few centimeters below the contact point when at rest. When the sculpture is tipped the center of mass swings under the pivot point in this stable equilibrium condition- no magnets needed to create this physics magic.

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.
