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: 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.

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.

 


Tesla's Plasma Mug

This plasma mug was sold in the 1990s but can be found on eBay often:
From eBay: BUY NOW: Plasma Mug

An improved and beautiful version sold here:
From Etsy: BUY NOW: Plasma Mug

Tesla’s Plasma Mug: this double walled glass mug glows orange from the excitation spectrum of neon gas at low pressure. The base contains a high frequency transformer that generates high voltage electric fields (but at very low current) from 8 AA batteries- which excites the neon to glow, and also serves as a coaster. This crazy item was produced by Can You Imagine Toys in the 1990s- perhaps Tesla himself would have served a good beer in this mug! 

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.

Surf's Up!

Kyle Auga-- kinetic sculptures: 
Check out Kyle's art here: 
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.

Click here for more on the PhiTOP and using magnetic induction to spin it up. 

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: 
From impossiblebottle.co.uk: Buy NOW Impossible Bottles by Philip Evans 

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.

Anamophic Cup & Saucer 

Mirror Anamorphic Cup & Saucer: the cylindrical mirror of the silver cup reflects and reveals the distorted scene of a carousel ride with four horses and the buildings of Macau Heritage City. The shape of the mirror allows for a mathematical operation, a type of affine transformation, to map the distorted image on the plate to the restored image reflected on the cup. A nice example of mirror anamorphosis through the medium of ceramics. 

Hydrophobic Water Maze

Wonderfully well crafted and available from this shop :
From Etsy store TheSmallestWorkshop:

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.

Nixie Tube

Nixie Tube Clocks 

Nixie Tube: 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. 


Orbit Spinning Top

Acrylic Wine Bottle Balance

Well Balanced Cabernet: a carefully engineered acrylic version of this famous demonstration- the center of mass of the rack/wine bottle system is directly over the base providing unstable equilibrium for this balancing act. Suspended here is Hypothesis by Roots Run Deep, an excellent Napa cabernet sauvignon. 

The ΦTop

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.
