Bouillant de Franklin Collection: my collection of vintage hand boilers, physics toys of blown glass that feature a reversible liquid-gas phase transition and demonstrates the relationship between temperature and pressure in an enclosed volume. The dyed fluid within each is typically dichloromethane which is in both liquid and vapor states. Heat from a hand, or from this catering warming tray, increases pressure in the bottom bulb pushing the liquid to the top bulb. Originally made famous by Benjamin Franklin, the first to describe the physics of its operation.

Mesmoid Kinetic Object: an elegant physical pendulum for the desk top demonstrates curious periodic motion. The pendulum, precision machined out of weighty polished brass, is a cylinder with an eccentric circle cut out. When set in to motion on the supplied smooth black marble slab, the Mesmoid will rock back and forth for three minutes or so until friction slowly dissipates the kinetic energy and the system comes to rest. The latest in a series of amazing kinetic objects created and designed by physicist and artist Kenneth Brecher.

Jansen’s Linkage Walker: a mesmerizing motorized sculpture that features Jansen’s linkage- a unique leg mechanism which converts rotary motion of a crackshaft into smooth walking motion. The linkage used here was invented by artist Theo Jansen for his “strandbeest” creations which are usually a couple meters high and walk the beaches of the Netherlands powered by the wind. This kinetic sculpture is powered by two AAA batteries and comes with complete with display stand.

Sonic Photonic Visualizer: a laser reflects from a small mirror mounted on a stretched rubber membrane which allows the projection of complex curves produced by the deformation of the membrane from sound waves. Yet another amazing kit from the VSauce team at @thecuriositybox which uses a balloon as the membrane for the top of the “drum”. The membrane is most sensitive to sound waves in the bass and midrange frequencies and I got the best reaction with my Bluetooth speaker playing Moon Flower by Tahüm- a snippet of which is featured here.


Kinetic Wonder Rings

Assorted colors to choose from:

From Sling True: BUY NOW: Kinetic Wonder Rings

Note: this site contains affiliate links for which I may be compensated

Kinetic Wonder Rings: a skill toy that features small rings that “roll” down a thicker steel ring while producing a distinctive ringing chatter sound as they go. Swiping the small rings gets them spinning and gives them angular momentum. Centripetal acceleration then keeps the inside of the small rings in contact with the steel ring so that they roll around as they descend (seen here in 240fps slow motion). The challenge is to rotate the large ring fast enough to keep the small rings in motion. A new take on the “Jitter Gyro Ring” 1990s skill toy craze, produced by Sling True toys.

Phenakistiscope Spinner Set

From Etsy: BUY NOW: Animation Spinners

Phénakisticope Spinner Set: two spinners- one a laser cut and printed acrylic with a set of images similar to the animation design of a flip book (but in a repeating cycle)- and the second a black disk with thin slit openings. Spin them in opposite directions and then look through the black disk at the first to reveal an animated image, in this case a running stick person. The effect looks better in person in that the frame rate of the video capture process adds some artifacts. Using the second black disk like this turns the spinners into a phenakistiscope, the 1833 invention that started moving media animation that lead to the development of movies and video. Under very bright light the animation can also be seen using a smartphone camera in video mode, but the black disk allows one to see the animation without such technology.

Specular Hologram Knot: this complex 3D image is created by etched grooves that reflect a point source of light as glints, and each eye sees a slightly different pattern such that, via stereopsis, the shiny points appear to float above or below the surface. Complex mathematical equations must be solved to compute the shape of the thousands curves that are scratched into the surface of the metal plate. The artwork featured here is a creation of Matt Brand of Zintaglio Arts. 

 

 

Maxwell's Top

From Grand Illusions: BUY NOW Maxwell's Top with Spiral 

Note: this site contains affiliate links for which I may be compensated

Maxwell’s Top: a new miniature version of one of my favorite demonstrations of the strange properties of rotating bodies- based on a famous experiment by the great physicist James Clerk Maxwell. When this bell shaped brass top is spinning an interesting stability can occur- push on the stem with an object and the top will push back, forcing the stem against that object, and friction will cause the stem to roll along and trace the edge of the object. In this design the stem will trace along the edge of a metal spiral, clinging to it like a magnet- but magnets are NOT involved here. The key to this design is to make the contact point/tip of the top at its own center of mass, then any frictional force in contact with the stem will produce a torque about the contact point at right angle to the direction of friction that creates the stabilizing force (students of physics may recognize application of the right hand rule here). An extreme physics toy- beautifully designed and crafted by Kontax Engineering Ltd

Galton Boards: Small and Large

Available here: 
From Amazon: BUY NOW: Desk Galton Board 
From Amazon: BUY NOW: Display Galton Board (comes with an wonderful fact filled booklet). 

Note: this site contains affiliate links for which I may be compensated

Galton Boards Large & Small: 6000 steel balls vs. 3000 in the compact version. Each ball has a 50/50 chance of going left or right at each branch such that the balls are distributed at the bottom by the mathematical binomial distribution (12 layers for the desk version, 14 layers for the deluxe). In addition the number of balls in each bin can be predicted by Pascal’s triangle, where the number on each hexagonal branch point represents the number of possible paths to reach that point from the top. Two extraordinary designs by Philip Poissant and the best version of the Galton Board since its invention by Sir Francis Galton(1894). An amazing demonstration of the Central Limit Theorem for the home or classroom!
