Fidget Toys - Should YOU buy one?

[@physicsfun]

Hello Everyone! I bet many of you can’t answer these 👉🏻 03:51 👉🏻 07:42 Let see how many get this right! Where are you all from 🌍?

[@JameisonAus_YouTube]

happy new year from australia!

[@rajulvalsan5020]

The angle between blue and orange arrows was 90 degrees. How did it become 180 degrees.

[@physicsfun]

Happy 2023 🎉

[@puspamadak]

The laser light propagates by the phenomenon of "Total internal reflection" At 03:51 - When the animal is at the opposite end of the table, the string have enough force in the horizontal direction to pull the animal. But when the animal reach to the edge, the string pulls vertically downwards, hence no horizontal component of force acts on it. That's why the animal stops.

[@puspamadak]

@@rajulvalsan5020 The angle between blue & orange arrows stay 90°. At last, the card itself was flipped. Before flipping the blue was pointing at 45°. On flipping, blue became 135° (behind). Orange is now towards 225°. So, angle between them is 90°.

Total internal reflection.

[@bluecat2991]

3:51 This one is actually pretty fun! Gravity, thanks to the weight dangling off the end of the string, produces tension which pulls the elephant forward. A rocking motion, induced by the hand, releases one pair of legs before swinging back to engage the other set. Because the string is fixed to the elephant and not to a wind-up mechanism it stops at the edge because the tension itself is not enough to lever the elephant up and off the edge due to its direction of pull, namely straight down.

[@stoopidbastid6420]

its because the force is downward nor forward. You probably should not try to answer any more questions.

[@baptistek1917]

Gravity does not exist. Buoyancy and density sort everything out.

[@ShubhamKumar_neet]

TIR(Total Internal Reflection) another example of this phenomenon i.e. "optical fibre". I ❤ PHYSICS+FUN

[@purplealice]

Reflection. The light waves travel by bouncing back and forth from one side of the fiber to the other - the surface between fiber and air acts like a pretty good mirror.

[@goodiesohhi]

It's more specific than that, it's TIR

[@Yjn75]

Whenever the guy says "wait for it" he does really mean just wait for it to finish. It's not like something surprising is going to happen in the end.

[@radagastaddams3703]

i got one of those magnetic cubes that unfolds into 2 or 3 million different geometric shape &....... it stresses me out because once it's unfolded it takes ages to work out how to get it back into a cube again. so it just sits there on the table, quietly mocking me with it's geometric smugness

[@wafiuddinakbar9150]

That's like fiber optic (refraction). Where data sent by fiber and if at the middle was broken, it wont be sent to the end.

[@krishnak6591]

7:43 I think it's due to internal reflection. I'm right?
