for @physicsfun Instagram followers
I get asked often: "Where did you get all this stuff?" My goal is to share the real magic of science and physics- and to this end I will update here (and in my store) suggestions on where to get some of these toys, kinetic art pieces, and scientific curiosities for yourself. Purchasing items from the links on these pages will help support my IG page of science and wonder.

Specular Hologram on Vinyl

For the price of a vinyl LP you can own the amazing artwork of Tristan Duke. This album by Jack White is damn good as well (I also got the digital download with the vinyl purchase). 

From Amazon: BUY NOW Jack White Lazaretto (Vinyl) 

Specular Hologram on Vinyl: the album Lazaretto by Jack White features this amazing "scratch hologram" of a twirling angel (shown here accompanied by the opening bars from the title track of the album). The hologram was hand etched on the metal master by artist Tristan Duke of Infinity Light Science. The etched grooves reflect a point source of light as sharp glints and the groves are arranged so that each eye sees a slightly different pattern such that, via stereopsis, the shiny points appear to float above or below the surface. This album has a lot of other interesting features including dual grooves that allows for two different intros to one track (depending on where the needled is dropped) and side A plays from the inside out- fun! 

Photicular Dinosaur Book

From Kainen and Wollard: 
From Amazon: BUY NOW Dinosaur: Photicular Book 

Click this link for the other amazing books in the series.

Photicular Dinosaur Book: the latest in the photicular series- this time with scientific reconstructions of ancient beasts! This amazing book of 8 astonishing moving and looping lenticular images is the creation of photographer/artist/inventor Dan Kainen where the moving images use Kainen's patented process where a specially processed image slides under a thin film of lenticular lenses. Kainen has teamed up this time with Kathy Willard who puts each image into context incorporating fun paleontology facts appropriate for kids yet informative to all.  

Pluto Globe by MOVA

Available here: 
From BUY NOW Pluto MOVA Globe 

Wikipedia has a wonderful summary of the 2015 Pluto flyby and the complete mission of the New Horizons space probe. 

Pluto Globe by MOVA: simulate the historic 2015 Pluto flyby of NASA’s New Horizons space probe with this self rotating detailed image of the dwarf planet’s surface. Each MOVA rotating globe is sealed within a clear liquid filled acrylic sphere. The rotation is powered by light that shines through the semi-transparent Pluto globe on to solar cells inside the globe which drive a motor. But what does the motor push against to maintain the rotation? Believe it or not it uses magnets to push against the Earth's magnetic field like a compass needle. Love this clever device. With thanks to @movaglobes for sending me this amazing globe. 

Rattlesnake Eggs

Get a set here! 
From Amazon: BUY NOW Buzzing Magnet Set 

Rattlesnake Eggs: polished barium- strontium ferrite ceramic magnets influence each other when many centimeters apart. Turn sound on--Wait for it! Sold as "buzzers" these magnets come together with multiple bounces creating a characteristic zipper sound. Most shops and online vendors incorrectly label these as hematite- a completely different substance that does not magnetize well. 

Fiber Optic Galaxy Lamp

These lamps can often be found on eBay: 
From eBay: BUY NOW Fiber Optic Lamps

Fiber Optic Galaxy Lamp: a vintage 1970s fiber optic lamp with a chrome “UFO” base. Note the beautiful spherical symmetry of the fiber spray- they don’t make them like this anymore! The fiber bundle is illuminated by a lamp in the base and the color shifting patterns are generated by a rotating color wheel placed between the light source and the fiber optic bundle. Fun physics at a thrift store price.

Light Pipe

Get one here: 
From Amazon: BUY NOW Display Stand Light Pipe 

Very inexpensive LASER pointers available here: 
From eBay: BUY NOW Green Laser Pointer 

Light Pipe: internal reflection constrains most of the laser light to propagate along the bent acrylic rod- the physics of fiber optics. This plastic stand is sold as a hanging ornament display- repurposed here as a great light-pipe demonstration.

Swirl Around Top

Available on eBay (2 current to this post) 
From eBay: BUY NOW Vintage Swirl Around Top 

Fun and inexpensive magnetic tipped tops: 
From Amazon: BUY NOW Magnetic-Tipped Tops 
From eBay: BUY NOW Magnetic-Tipped Top

Swirl Around Top: the magnetic tipped top stays on the perimeter of the steel plate template- but since the top has more mass than the triangular plate, the triangle moves in an interesting way. This kinetic art toy takes advantage of Newton's 3rd law and rotational kinetic energy. Produced by The Toycrafter in the 1990s these tops are out of production but can often be found on eBay. 

TV Rock

Get an inexpensive "true blue" (not UV) laser here: 
From eBay: BUY NOW 445nm blue laser pointer 
Click on this link for sources of inexpensive TV Rocks 

TV Rock: special crystalline form of the mineral gypsum acts as a natural fiber optic image conduit. A laser reveals a couple of interesting properties of these crystals: When directed along the grain of the fibers the laser beam emerges a circle of light (445nm blue used here). In addition, these crystals form with internal cracks, and reflection of laser light off these boundaries reveals the sectioning structure as each domain lights up. Morocco seems to be the main source of this fibrous form, called satin spar gypsum, which exhibits pearl like luster and chatoyancy along two axes and transparency along the direction of the fibers. Not to be confused with ulexite, a mineral of boron with similar TV rock properties. 

The Helicone

Get one here: 
From Amazon: BUY NOW Helicone Interactive Kinetic

This manipulable kinetic art available here: 
From Art of Play: BUY NOW 
The Helicone

The Helicone: an interactive kinetic sculpture designed by @john.edmark and distributed by playableArt. With a bit of practice I finally mastered the transformation in both directions: A snap of the wrist imparts angular momentum to the laser cut wood 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. 

Levitron Revolution

Get the levitating/rotating platform here: 
From Amazon: BUY NOW Levitron Revolution 
From eBay: BUY NOW Levitron Maglev Platform 

Versions of the floating rings illusion can be found at the Exploratorium, at the Carnegie Science Center
and is also famously featured in the 1981 Superman movie: 

Levitron Revolution: well engineered control system uses an adjustable electromagnet and and a Hall effect sensor to levitate an 8cm diameter neodymium magnet platform 5 cm in mid-air. The feedback loop allows fine tuning of the magnetic field to exactly balance the pull of gravity. The platform also rotates, perfect for this floating rings illusion sculpture I constructed. 

Thermocromic Eclipse Postage Stamps

Available from the US Post Office and here: 
From Amazon: BUY NOW Thermochromic Eclipse Stamps 

Thermocromic Eclipse Postage Stamps: In commemoration of the total solar eclipse next Monday the US Post Office has released their first ever stamp featuring thermocromic ink. Thermotropic liquid crystals go from opaque to transparent during a phase change from a crystal to liquid state. Here the warmth of the hand reveals the face of the moon in front of the solar corona. The first physics toy stamp!
