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
Vibration
You could use ‘Howling’ by Lupus Nocte
Du to vibration
This is due to the vibration produced when we rub the stick on the toy
The solution of the challenge is that the vibrations cause it to spin
Due to vibration
Vibration
Where did the screw (in the first gadget) disappear to???
Vibration
i know the answer look in 10 s in second clip
Vibration
My answer for the quiz
Vibrations cause the stick with notches to shake, which moves the propeller
Vibraton
Quiz: vibration make it turn faster
I have to take a dump so bad
Vibration
vibration same as 0:06
The vibrations of the stick viberate at the right frequency to turn the propeller
vibration makes the fan spin
It is due to resonance frequency
Background music: Orns battle theme
Depends where the pointing finger is. Over the ridge, clockwise, this side of the ridge, anti.
Megalovainia
Because of the vibrations
Actually it is a Japanese toy
Same screw and nut theory
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
Ans:because of the vibration
Background music suggestion:opinions (my friend wont tell me who its by)
The Background Music ist wonderful, good for this awesome projects.
Maybe it is like the bolt and the motor
Vibrasjon
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.!!
Solution needs EXPLAINING
Faded

Love ur toys bro
It spins by vibration
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.
I created my own music
This is due to vibrant
Background music…..interstellar theme music …it will be super
Because of the vibration
Welcome to the party deadpool 2
Challenge and bonuses: vibrations
It’s because the linear motion is converted to centrifugal force same happens with the crankshaft in car
Awsome toy who gave you these toys your school teachers.
Vibration
Marshmallow alone
