This video contains:
👉 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
👉 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

one of the best channel I have seen ever Hat's off to you guys💐
-
Muy asombroso todo. Felicitaciones a las personas involucradas en este tipo de videos
-
3:10 It should be on my way
-
I want them all :D mostly the last two ( In bonus) :p
-
LoL! I thought My Headset is Damaged 🤣🤣🤣
-
Damn man .... I love your work and really want to see your face.
-
The Background Music ist wonderful, good for this awesome projects.

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
-
fun fact. magnetic opposites attract. so if your compass points north, its pointing to the south pole. or you could argue the north point of the magnet is actually mislabeled and is actually the south point on the compass pointing north...
-
The Vibrating edges are designed for round move alternately < left and right > side so while vibrating, also produces some round movement of top, causing fan round movement. Plz suggest if my guess is false.
-
The last of us part 2 has 'Crooked still (Ecstacy)' Music you should try in next video
-
Great experiments, I appreciate watching them. For the music - I would avoid the excessively staccato rhythms and use some ambience music, or some soft sinthpop.
-
Vibration at an accurate frequency leads in rotation
-
Vibration. I like ur questions of every week
-
Gotta love any video with a gee-haw whimmydiddle!
-
My guess on today quiz: When the stick rubbing the notches, there will be a vibration appear and make the nail spinning. Because the nail and the propeller were attached, the vibration from the rubbed stick will spread to the nail and tada! The nail was spinning (sorry if my guess are wrong, i'm not good at physics ;^;)
-
that's why because whenever the stick comes down slope by slope it makes some force that vibrates the stick in a fixed way. the fan rotates when we constantly rub the stick bcoz of vibration....
-
For the hyperbolic holes, I remember that if you make a line (the pencil) rotate around a line which is not in the same plane as the other (the vertical axis in this case), you get an hyperbolic hyperboloid. The section of this surface with a plane can be an ellipse (not this case) or an hyperbola (this case). I think that's why the pencil fits trough that hole.

Amazing
