Fun fact: the second one is called pykrete, and the MythBusters did an episode on it where they made a working boat out of it.

Not even animating it could make the last one look like it's not slipping.

I knew the last one was fake because of veritasium, the animation also made it pretty obvious

The first video is actually really cool. Basically what you’re doing with the strong magnet is aligning magnetic domains in the iron (which are normally scattered around) in one direction so that they act like their own permanent magnet. Imagine it’s like combing magnetic hairs, and when they’re all combed, they become a magnet. You can do this with almost anything made of steel.

Whenever you have something rolling around something else, it will make an extra rotation. To clarify, when you look at the two coins from an outside perspective you will see the coin rotate twice, but if you set a camera on the rotating coin, it will look like the coin only rotates once. The same thing happens with Earth going around the Sun. We experience 365 24-hour-long days in one year, but someone looking at the Earth from somewhere outside the solar system would see the Earth having 366 23-hour-and-56-minute-long days in one year. Since the Earth is moving while it's rotating, it actually needs to turn more than 360 degrees to point back at the sun again, and it takes 4 minutes to turn this extra distance. Also, this is the reason the constellations change and move across the sky, since they have this outside perspective. So if one night you go out at 10pm exactly and point your telescope at Rigel, then leave it that way until the next night, you will be able to see Rigel in the same spot at 9:56pm but by 10pm it will have moved a bit.

Fun fact: there was a proposal to build an aircraft carrier out of ice mixed with wood shavings, as its actually quite resistant to melting, and it's quite durable, buoyant, and cost effective.
the 2nd clip is somewhat reminescent of that

For those who are wondering about the second one, when through paper isn't particularly strong, it is certainly impact resistant and doesn't exactly tend to shatter. By placing trips of it into somthing brittle, I creates a form of armor that is almost impenetrable to everything. The example shown is a simple one you can do at home, however this concept can be taken Thurbher by mixing titanium and carbon nano-tubes, even in lower percentages like 0.3% to create an aloy which can only be destroyed by melting it.

Physics and veritasium do be always helping me in life 👍

The towel ice cube is a decent demonstration of how fiber composite materials work (fiberglass, CF nylon, etc.).
The random arrangement of fibers can give a composite better mechanical properties than the base material by allowing it to take more stress in different directions. This is also what allows pykrete to work (although it uses wood pulp and is more like a particulate-reinforced composite).

1: thats how everyone made water glass compasses in grade school
2: pykrete

Clearly the only one with an animated solution that would be the easiest to actually show!

Fun fact, if you wanna be lazy with it you can just leave the screwdriver on the magnetic over night. I accidentally did this to my sewing scissors with a magnet pin cushion

I’m a nerd for math and the famous incorrect SAT question sort of gave this away 😂

bro rlly hit that 2nd ice cube like it was a turboflex product 💀

Ooooo, this one is good! Unfortunately I realized the last one must be nonsense since the coin is sliding around it, basically the same letters remain in contact the entire time

This channel reminds me of quirkology. All you need now is a catchy jingle 😅

At this point it’s more about thinking how it can be faked over guessing which ones are real

the second one is called pykrete, and in WW2 they tried to make boats out of them...

I’ve watched a few of these and haven’t missed one yet. And yes, I’m patting myself on the back.

When he cut to an animation instead of live footage I knew that was the fake 😂
