AMAZING MAGICAL SCIENCE TOYS TO MAKE YOU SAY WOW!6

New Video 👉🏻

Hi Everyone :)
Welcome back!

I get asked often: "Where did you get all this stuff?" My goal is to share the real magic of science and physics- and to this end I will update here (and in my store) suggestions on where to get some of these toys, kinetic art pieces, and scientific curiosities for yourself.
Purchasing items from the links on these pages will help support my IG page of science and wonder.

This video contains and involves phenomena in each clips :

00:00 Mirror Anamorphosis: this famous print by artist István Orosz has a hidden anamorphic image revealed by placing a mirrored cylinder over the depiction of the moon in the image.

00:23 Magneto Top: a top that generates electricity and lights LEDs when spun. This top contains a strong dipole magnet which becomes the rotor in this alternator set up. A 1000 turn coil in the base can be adjusted so that the rapidly changing magnetic field of the top will induce an AC current in accordance with Faraday's law.

00:58 Reflective Wind Spinner: this one translates rotating motion into a repeating expanding (or shrinking) circle.

01:26 Lenticular Invisibility: this thin acrylic sheet is comprised of tiny cylindrical lenses which can allow images to be “out of focus” along one dimension which blurs thin images and hides them. This 70 lens per inch sheet is part of a lenticular optics kit that came as part of my thecuriositybox subscription.

01:49 Perspective Puzzle: twelve flat images, when ordered and spaced correctly, combine to produce this 3D illusion of structure and depth.

02:23 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.

02:50 Bimetal Seesaw Engine: candle powered heat engine- with bears!

03:40 Nitinol Paperclip: nitinol is a special alloy of nickel and titanium that can be trained to a specific shape at high temperature- in this case the shape of a paperclip.

04:05 Steam Engine with Generator: celebrate the Industrial Revolution on your desk top with this working model which includes a horizontal piston steam engine complete with boiler, whistle and a flywheel which itself is connected via belt and pulleys to a generator that powers a street lamp replica.

05:29 Magnetic Repulsion Fidget: a strong dipole magnet is suspended between two more dipole magnets, one fixed to each end.

I have a reflective spinner that's over 20 years old. Lost its Shine years ago but still spins. I've thought about stripping it bare and having it chrome plated. My Wife bought it on our Honeymoon and our Silver Anniversary is coming soon, so I thought it would be nice to celebrate it by giving it its Shine back in a better way. 👍

Gadget 4. How can the foil show the orange crayon without interruption. The green one is lying on top. How does the foil know that the orange is below and continues below the green one. 😮

[mikebritton]

That fidget toy would become a habit. I couldn't put it down.

7:42 i used my spatial thinking and memory to answer this question quite easily. here we have a blue arrow. rotation showed an orange arrow that points left. if i think what behinds those blue arrow after this context, it is orange arrow pointing to the right. when they rotated it, I can't exactly describe, but can describe approximately specifically at first with exact path, i answered "75% right and 25% left", indicating the orange arrow slightly points down while its mostly right. all before i saw an angle.

About the lenticular visibility
I know it is possible to see only lines that in a specific direction
But it is impossible to see them if they are behind or covered with something
So how do the four orange pencils look complete and normal when there is a pencil on top of them

Is the magneto top available anywhere at a reasonable price?

Newton's 3rd Law of Equal & opposing forces: If the centripetal force is real, then so is the centrifugal force. One just needs to keep track of one's reference points.

My answer for the quiz is 135, but just a guess from what I'm seeing! That seemed too easy to me, so might be wrong.

[martinwest]

The orange arrow points 90 degrees tilted from the blue one, and on the back side it points to the right from the camera/viewer. if you then turn the blue arrow 45 degrees to the right, the orange follows, pointing on the backside at 135* Since no one has told the plate would be flipped to view the orange arrow, it surely points to 135* on the backside in the picture in the video. Thus this would be the right answer. However, if we then - against directives - turn the orange side against the camera, it will point in the opposite direction, that is 225 degrees.

Edit: On closer inspection there surely was - for three seconds in the end - the text "when flipped". This particular information should have been visible straight from the beginning, as it is crucial to lead to the answer you sought for. The answer to your initial question "which way will the orange arrow point after right rotation of the blue arrow?" is - as so many commentators correctly stated - 135 degrees.

[gaijininja]

225°. It is facing the 135° position when the blue arrow is facing us and pointing at the 45° position.

[DonnyHootieHoot]

What? On Amazon these "toys" are THOUSANDS of dollars! What?

[nenel]

The arrow would be pointing down. I would be interested in getting this venticular invisibility.. for my window I've been watching your program since 2075.

The first image is like the cover of Rick Wakeman album, No Earthly Conection tha ca.e with a piece of mirrored mylar to make a cylinder out of and view the cover of the album.

How the hell does one escape from this

👍👌👏 Oh WOW, simply fantastic. Thanks a lot for making explaining recording editing uploading and sharing.
Best regards luck and health in particular.
