About this video :

👉 Vibration Unthreading: a DIY project to see if just shaking a bolt at the right frequency could make a standard nut rotate and fall off Similar physics to the phase locking propeller toy featured in my last post. Motivated by videos seen on Instagram where a brass bolt is placed in magnetic putty and the nut mysteriously rotates up and off- now convinced that vibration is how that effect is produced. Here a small DC motor spins an offset mass to produce the vibrations.

👉 Spin Bank: a clever spring mechanism launches each coin into rotation along a symmetry axis on to a concave trapping surface. Angular momentum of the spinning quarter keeps it upright even as it bounces upon impact with the platform. Another spin on making saving spare change fun!

👉 Hyperbolic Holes: a straight rod, in this case a pencil, glides through a symmetrical pair of curved holes. The design is based on the hyperboloid, the 3D ruled surface traced by an offset rotating diagonal line. This device is sold as an inexpensive kit to assemble yourself, and includes a motor with geared drive and pre-cut pieces. The pencil is my addition- just the right size to clear the curved openings.

👉 “Top Secret”: this top will stay spinning for more than a week- because it is actually a motor! The top is a dipole magnet (as revealed by Magneview film) and the base has an electromagnet that gives the dipole a push when the top comes near the center. An ingeniously simple circuit consisting of only a battery, a coil, and a transistor, is activated when the spinning magnet nears the coil turning on the electromagnet to give a boost to the spin of the magnetic top.

👉 Pendulum Snake- one of my favorite exhibits at exploratorium: ten swinging spheres, the first has a frequency of 15 swings per 30 seconds, the second has 16 in the same time, the third has 17, up to the tenth with 24 swings per 30 seconds.

👉 Magnetic Pendulum Array by exploratorium: 21 aluminum pendulums, each with a large magnet affixed to the end. The magnets allow kinetic energy to be shared. Note how the energy of the end pendulum is transferred to the rest in two steps- 1) the magnetic fields interact to damp the motion until 2) the end pendulum is captured into synchronized motion with the rest, allowing the energy to propagate to the front pendulum.

👉 Heat Pipe: a device that transfers heat with great efficiency- as demonstrated by this fantastic kit from educational innovations . Here a liquid crystal goes from green (room temp) to black (near freezing) showing the heat transfer to a piece of ice through a heat pipe (top) and a similar sized piece of solid copper rod (bottom).

👉 Toy Car with Magnetic Suspension Wheels: Simple block car with clever wheel design. Small neodymium magnets embedded in the block lock on to steel balls, which raise the vehicle and become free to rotate providing the wheels for this simple toy.

👉 Diamagnetic Levitation: tiny neodymium magnet trapped between two diamagnetic discs of graphite. Diamagnetic substances only have magnetic fields of their own when placed in an external magnetic field. Diamagnetic fields are pretty weak, so the top magnet is adjusted to help lift the tiny magnet against gravity.

👉 Galileo Drop Tubes

👉 Foucault Oscillator: like a swinging pendulum, the motion of a mass on the end of a straight wire spring is constrained to a plane. The container is moved around yet the orientation of the oscillating mass points in the same direction. Similar to the physics behind the famous Foucault Pendulum that keeps its orientation as the Earth moves underneath.

👉 South Pointing Spoon

    Use sleepwalking from the chain gang of 1974 and don’t come close by yeasear for background music

  2. bey ninjas on November 23, 2019 at 12:45 am

    Vibration

  3. Kingcraft0529 on November 23, 2019 at 12:46 am

    You could use ‘Howling’ by Lupus Nocte

  4. SURAJ LAKHERE on November 23, 2019 at 12:47 am

    Du to vibration

  5. prisha gulati on November 23, 2019 at 12:48 am

    This is due to the vibration produced when we rub the stick on the toy

  6. Kronky Bonky123 on November 23, 2019 at 12:52 am

    The solution of the challenge is that the vibrations cause it to spin

  7. Chaudhary 3779 on November 23, 2019 at 12:53 am

    Due to vibration

  8. Evelyn Scott on November 23, 2019 at 12:53 am

    Vibration

  9. Nameless 1 on November 23, 2019 at 12:54 am

    Where did the screw (in the first gadget) disappear to???

  10. Ashish jagwani on November 23, 2019 at 12:55 am

    Vibration

  11. Glenda Nonsol on November 23, 2019 at 12:58 am

    i know the answer look in 10 s in second clip

  12. Beena Beena on November 23, 2019 at 12:58 am

    Vibration

  13. Tyler Brink on November 23, 2019 at 1:03 am

    My answer for the quiz

    Vibrations cause the stick with notches to shake, which moves the propeller

  14. DeGamedemoon on November 23, 2019 at 1:03 am

    Vibraton

  15. Fireboss 05 on November 23, 2019 at 1:04 am

    Quiz: vibration make it turn faster

  16. Paul Hernandez on November 23, 2019 at 1:04 am

    I have to take a dump so bad

  17. Gaviola Ernanie on November 23, 2019 at 1:05 am

    Vibration

  18. buttery chesse on November 23, 2019 at 1:06 am

    vibration same as 0:06

  19. CJ Cubing on November 23, 2019 at 1:06 am

    The vibrations of the stick viberate at the right frequency to turn the propeller

  20. Rayyan thariq arsyandi on November 23, 2019 at 1:07 am

    vibration makes the fan spin

  21. Kamal Bhatiwal on November 23, 2019 at 1:08 am

    It is due to resonance frequency

  22. The Phoenix Kid43 on November 23, 2019 at 1:09 am

    Background music: Orns battle theme

  23. tecsonics on November 23, 2019 at 1:10 am

    Depends where the pointing finger is. Over the ridge, clockwise, this side of the ridge, anti.

  24. Xavier Valliere on November 23, 2019 at 1:11 am

    Megalovainia

  25. elnobby 22 on November 23, 2019 at 1:11 am

    Because of the vibrations

  26. Mili Shailendra on November 23, 2019 at 1:13 am

    Actually it is a Japanese toy

  27. Manigandan Sp on November 23, 2019 at 1:14 am

    Same screw and nut theory

  28. Christian Paul Manuyag on November 23, 2019 at 1:17 am

    Just like the first clip, the large stick with groves resembles the bolt and the propeller resembles the nut, as you shake the stick at the right speed (in this case, running a dowel on the groves vibrates the stick) makes the propeller spin

  29. Pramod Vishwakarma on November 23, 2019 at 1:18 am

    Ans:because of the vibration

  30. James Tomlin on November 23, 2019 at 1:18 am

    Background music suggestion:opinions (my friend wont tell me who its by)

  31. Frederic Heinrich on November 23, 2019 at 1:18 am

    The Background Music ist wonderful, good for this awesome projects.

  32. Saad Abbas on November 23, 2019 at 1:19 am

    Maybe it is like the bolt and the motor

  33. sander øyhus Pihl on November 23, 2019 at 1:19 am

    Vibrasjon

  34. Syed Mohd Adil on November 23, 2019 at 1:20 am

    The nail was moving due to the frequency created when the stick was rubbed on the notches, similar to when the frequency can make a standard nut rotate and fall off.
    For ex- If we set our phone in vibration mode, and if the frequency is very powerful than it will make the phone shake and sometimes it will also make it fall from the table.!!

  35. Zeus _ on November 23, 2019 at 1:20 am

    Solution needs EXPLAINING

  36. Ariyan Bhattacharjee on November 23, 2019 at 1:22 am

    Faded

  37. Jayalakshmi manimaran on November 23, 2019 at 1:25 am

  38. Krishna Gupta on November 23, 2019 at 1:26 am

    Love ur toys bro

  39. James Laurente on November 23, 2019 at 1:26 am

    It spins by vibration

  40. Astitva_official on November 23, 2019 at 1:26 am

    The propeller rotates because of Resonance because ut is attached to the center creating a Simple Harmonic Motion. This effect is known with different names i.e. if electrical called mutual induction, if wireless calked doppler’s effect.

  41. Art By Mahboob Akhtar on November 23, 2019 at 1:27 am

    I created my own music

  42. Lakshmi Sony on November 23, 2019 at 1:29 am

    This is due to vibrant

  43. Raki Palivela on November 23, 2019 at 1:30 am

    Background music…..interstellar theme music …it will be super

  44. Yowzon Alex on November 23, 2019 at 1:32 am

    Because of the vibration

  45. Sarita Srivastava on November 23, 2019 at 1:32 am

    Welcome to the party deadpool 2

  46. Marko Macík on November 23, 2019 at 1:33 am

    Challenge and bonuses: vibrations

  47. Prajwalshetty Shetty on November 23, 2019 at 1:33 am

    It’s because the linear motion is converted to centrifugal force same happens with the crankshaft in car

  48. Ariyan Bhattacharjee on November 23, 2019 at 1:34 am

    Awsome toy who gave you these toys your school teachers.

  49. Gaviola Ernanie on November 23, 2019 at 1:36 am
