This video contains:
00:01 Rolling Uphill Illusion: the ball bearings seemingly roll uphill as if attracted by magnets of some kind. What’s going on?

00:32 Micro Racer in a Glass: (a favorite demo) This tiny battery powered car overcomes gravity through centripetal acceleration and slight friction with the glass surface.

01:21 Dipole Magnet and Iron Filings: visualizing the invisible- the magnetic field lines around a dipole magnet.

01:46 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.

02:18 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 get pretty hot 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.

03:40 Levitating Inq Lamp: Inq (the curious orange octopus) hangs illuminated and suspended by magnetic forces.

04:04 Impossible Bottle Sculpture Puzzle

04:36 Tensegrity for the Desk

05:09 Hyperboloid Spinner: the HypnoGizmo toy consists of a set of slanted straight nylon lines arranged to form the outline of a hyperboliod- the quadratic surface related to the revolution of hyperbola around its axis of symmetry. As the device rotates the beads slide along in succession on one of the straight paths leading to the complex visual display. So much fun math in this toy!
