Precision Tippe Top

Get a flip over tippe-top here:   

From Amazon: BUY NOW Tippe-Tops 

Precision Tippe-Top: spinning things often have surprising physics! This aluminum version of the famous flip-over top works better than any I’ve seen. Friction with the desk surface provides a torque that acts on the existing angular momentum of the top to flip it over. The top will stay flipped until the spin rate slows down enough to where its center of mass pulls it back to the resting position.

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. 

Hero's Engine

This live steam engine is available here:

From EngineDIY: BUY NOW: Hero's Engine

Hero’s Engine: the very first steam engine ever devised, the Aeolipile is a radial steam jet reaction turbine, an a invention attributed to Hero of Alexandria in the year 1 AD. Water within the spherical container is heated to produce steam which exits through nozzles directed at right angles to the radial direction, and by Newton’s third law these jets produce a torque about the rotation axis. There is no historical record of this engine being put to practical use in ancient times- except perhaps as the world’s first physics toy!


Well Balanced Cabernet

From Amazon: BUY NOW Balance Wine Racks 

Well Balanced Cabernet: the center of mass of the rack/wine-bottle system is directly over the base providing unstable equilibrium for this balancing act. A fine wine rack for one bottle except during a 5+ earthquake, or if you own a cat. The oak wood for this wine rack was repurposed from the stave of a used wine barrel.

The color change employs leuco dyes, thermochromic chemicals that have two reversible forms, one colorless when wqrmed above a theshold temperature.

Strandbeest Mini

Get one here! Make sure to get the Jr. Scientist version of this kit for best results. 
From Amazon: BUY NOW Strandbeest Model Kit 

Read about Theo Jansen and his novel leg linkage mechanism for the Strandbeests via these Wiki pages. 

Strandbeest Mini: A fully working model of artist Theo Jansen's Strandbeest kinetic sculpture which features Jansen's linkage- a unique leg mechanism which converts rotary motion of a crackshaft into smooth walking motion. Jansen's creations are usually a couple meters high and walk the beaches of the Netherlands powered by the wind. This version comes as a model kit that snaps together with no glue- a really fun project!


The Lollipopter

Many styles/colors to choose from: 
From Amazon: BUY NOW: Lollipopter Kinetic Art 

The Lollipopter (The Helicone): one of my favorite interactive kinetic sculpture designs. With a bit of practice one can master the transformation in both directions: A snap of the wrist imparts angular momentum to the "petals" which then rotate until an internal mechanism stops their motion with predetermined spacing- a helix transforms to an abstract pine cone. A second snap of the wrist in the opposite direction returns the helix. A creation by artist John Edmark.

Advanced Gyro Hybrid Spinning Top

From PhysicsHack: BUY NOW: Advanced Gyro
Made with extraordinary craftsmanship and high quality materials, and sold at a very reasonable price! 

See also this other device by Mr. Fowler: Vortex Dome

Hybrid Gyroscope Top: the Advanced Gyro is a new design by @physicshack which exhibits a interesting vertical stability phenomenon when placed on this unique stand with three ball bearings that serve to minimize friction and keep the gyro centered. The top defies gravity, due in part to its angular momentum, and its spin axis slowly rises to a stable vertical position from subtle rolling friction interactions with the ball bearings. No pull cord needed, this unique design spins up via friction with a working surface (thin cardboard works well) and applying a circular motion to bring the rotor up to 1000s of RPM. Machined from solid stainless steel this top weighs in at about half a kilo, providing inertia that produces long spin times. Thanks to inventor/designer David Fowler for sending me this fantastic gyro. 

Tesla Coil

For the price, this is the best one on the market I think and beautiful to look at in copper- the music function does not do much, but it is a great little Tesla coil and it comes with three accessories for the top. Please be sure to employ all appropriate safety precautions when utilizing any electrical circuity! 

From engineDIY: BUY NOW: Mini Tesla Coil

Tesla Coil: miniature low current version of the famous air core double-tuned resonate transformer invented by Nikola Tesla in 1891. The thick copper of the primary coil is set into three windings around the many windings of the tall secondary coil. This one uses a modern transistor circuit to excite the radio frequency oscillations that produce a voltage in excess of 50kV in the form of pulses that cycle about 100k times a second. This version is fed by a 24V DC power supply and is fairly safe due to a low current (mA)- but the circuitry does get hot and demands a huge heat sink with fan (the metal base can burn skin when operating). The coils comes with attachments- the spike produces a purple corona discharge as the voltage exceeds the breakdown voltage of air with current flowing into the air or arcing over to a grounded piece of metal. The corona discharge imparts momenta, and here the ends of a bent wire are set into rotation from the slight push of the escaping electrons. Swipe to see the ejected electron stream propel the end of a thin wire into a final state circular orbit. The more interesting behavior occurs during the initial transient orbits which seem to be hypotrochoid type curves beautifully captured here using the Slow Shutter app. 


Plasma Arc Lighter Physics

Get one here- but like any source of flame- use with caution!  
From Amazon: BUY NOW Plasma Arc Lighter 

Plasma Arc Lighter Physics: dual arcs of plasma exceed 1100 C (2000 F) on this flameless lighter. The breakdown voltage of air is about 3000 Volts per mm. Thus the circuit in the lighter must provide about 12,000 volts to produce this 4mm arc. The circuit is a simple one made possible by a transformer with very fine wire windings, a transistor, and a powerful lithium-ion battery (USB rechargeable). The circuit produces high frequency current oscillations in the coils that in turn produce the needed high voltage. Like having a Tesla coil in your pocket!

The capsule is constructed of high quality glass on a heavy stainless steel base which glides upon an included bearing set for long spin times. 


Bismuth Maglev Rod

From Etsy: BUY NOW: 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.

Anamorphic Locomotion Cup & Saucer

Animated Horse set available here:
From Amazon: BUY NOW: Luycho Locomotion Horse Cup & Saucer 

CAUTION: There are poorly made counterfeit versions on Amazon as well. Only these origial Luycho products produce a clean animation and image.  

Locomotion Anamorphic Cup & Saucer: an amazing combination of barrier grid animation and anamorphic projection rendered on elegant porcelain. The warped image on the saucer is reconstructed by reflection off the surface of the cup, however the gold mirroring is comprised of parallel lines that only reflect part of the image pattern. Turing the cup (or the saucer and cup together) reveals a flying bird or running horse! Another expertly crafted product from Luycho.
