Infinity Mirror Tea-light Candle: parallel partially mirrored panes of glass create the illusion of multiple candle flames through the physics of reflection and refraction. Featuring candles from my collection this month as the winter solstice approaches.

Spinning Chimes Candle Holder in Brass
Scandinavian Chimes*: a simple heat engine- sound and motion from the resulting convection of candle flame. Another in this series of physics with candles- in celebration of the solstice! All parts stamped out of thin metal with assembly required =) *made in China
Many versions of this type of convection candle are available:

Spinning Snowflakes Convection Candle: a simple heat engine- rotational motion resulting from the convection of hot air due to the candle flame of a tea light. All moving parts of thin stainless steel with some assembly required. Energy transfer: chemical bonds to heat to kinetic energy of the rising air to rotational kinetic energy of the turbine and snowflakes.
Holiday Pyramid: a simple heat engine- rotational motion resulting from the convection of hot air due to the candle flames of two tea lights. These holiday decorations come from a German Christmas tradition, Weihnachtspyramide, that dates back more than 200 years! Energy transfer: chemical bonds to heat to kinetic energy of the rising air to rotational kinetic energy of the turbine and reindeer.

From Amazon: BUY NOW: Heart Hologram Specs
I ❤️ Holograms: put on these specs and every source of light gets a holographic image of a heart overlaid- in this case a candle flame and a dot from a red laser. Usually these kind of images need a point source of light, whereas these glasses put a heart image on every light- but they also make everything else a bit blurry! The "lenses" in these glasses are actually transmission holograms with the image located at the farthest point in the depth of field.
Tea Candle Steam Engine: a functional piston steam engine complete with boiler and flywheel. Takes about 2 minutes to get going after the candle is lit. The invention that powered the industrial revolution on a desktop! Made by Wilesco.
Diffraction Spectrum Candle: a thin plastic diffraction grating surrounds the flame in this rainbow producing design. The rainbow spectrum is produced not by refraction like that of a prism, but instead by diffraction, where light waves deconstructively and constuctively interfere.

From glasperlenstern.de: BUY NOW: Glass Bead Star Tea Light
Dresden Glass Bead Star: concentric designs of spherical glass beads produce geometric symmetries of shadow and refracted light from a tea light candle which serves as a point source of illumination. This “Glasperlen Stern” candle holder is one of many configurations offered from Dresden artist Andreas Schildhauer, each with glass set into porcelain from Freiberg.

From Grand Illusions Ltd.: BUY NOW Floating Steam Engine
Engines of similar design are used in pop-pop boats
Tea-Light Floating Engine: a candle powered super simple steam engine. The engine is just a coil of copper tubing filled with water. Steam builds up pushing water out with an explosive jet- which then results in a vacuum in the coil which pulls more water in to repeat the process. The water expulsion is in the form of jet directed out the end of the tube whereas the refill comes back in to the tube from a larger range of angles- so on balance the engine moves opposite to the direction of the jets.
This DIY project is pretty easy to build. One half of one of these inexpensive magnetic necklace clasps will work well for the heated magnet.

A full engine is available from my friends at Grand Illusions Ltd:
From GI LTD: BUY NOW: Curie Engine
Curie Point Heat Engine: when the magnet on the end of the wire heats up to a particular temperature (the Curie point) its magnetic field is temporarily lost until it cools. This engine design uses a second magnet to pull the swinging magnet back into the heat source once the magnetic field is reestablished. Repetition of this process creates mechanical motion as long as the heat source is fueled.

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!
