NASA have made a wheel capable of withstanding tough Martian terrain, but just how indestructible is it? Head to https://hensonshaving.com/veritasium and enter code 'Veritasium' for 100 free blades with the purchase of a razor. Make sure to add both the razor and the blades to your cart for the code to take effect.

A huge thanks to everyone at NASA Glenn Research Center for having us at the SLOPE Lab, showing their work on this indestructible tire, and helping with the science and animation.
A huge thanks to everyone at Smart Tire Co for showing us around their facility, teaching us about nitinol, and letting us flatten their tires.

That one guy thinks a normal bike tire is at 100psi?!
@originalacousticguitar Says:
So this video is 3 years old. Where are my indestructible tires? Or is it that these are so ridiculously expensive to make it’s not practical.
@Augmented_AI Says:
This will be death of the tire industry 😂. No more expensive tires or tire replacements.

Wow it doig steal u get normal stealth and get it up then u hard it the u clean heat again don’t quench in oils oil a drop or oil will make a crack so clean very well a het up again and then Qunch in water only to get spig steal hard bassklu het up 3 x quench 3times and u make sprig steal shape it before 3 x

I have an idea, you could make cubes or triangular prisms and use them as ammunition, when they are heated by the gunpowder, the form into an aerodynamic shell.

The Four Stages of the Shape Memory Cycle
1. The Austenite Phase (High Temperature)
At high temperatures, the material exists in the Austenite phase. This crystal structure is highly ordered, symmetric, and "rigid." This is the material's "parent" or "memorized" shape. Any configuration set here becomes the baseline the material will always try to return to.
2. Cooling to Twinned Martensite
As the temperature drops below a critical point, the atoms rearrange into the Martensite phase. However, to avoid changing the overall external shape of the object during this transition, the crystals form a "twinned" structure.
Self-Accommodation: The crystals tilt in alternating directions (like a zig-zag pattern) so that they cancel each other out on a macro scale. The piece of metal looks exactly the same to the naked eye, even though its internal structure has changed.
3. Deformation (Detwinning)
When you apply stress to this cool, twinned martensite, it feels "soft" or plastic. Instead of breaking atomic bonds, the stress causes the "twins" to flip and align in a single direction. This is called detwinning.
Macro Result: The material undergoes a large, visible deformation (often up to 8% strain).
Residual Strain: When you let go, the material stays deformed because the detwinned martensite is stable at low temperatures.
4. Heating and Recovery
This is where the "memory" happens. When you heat the material back above the transition temperature:
The detwinned martensite becomes unstable.
The atoms are forced back into the high-symmetry Austenite arrangement.
Because there is only one way for the atoms to fit into the Austenite lattice, the material must physically move back into its original high-temperature shape to accommodate the shift.

Question: How effective are these mesh tyres in extreme muddy conditions? Will they work? How will you remove the mud from the mesh?

Shape memory alloy: somehow first learned about this in 1998 when Solid Snake was conned into activating Metal Gear. How is Kojima always so ahead of his time. Hope other players recognize this immediately… that huge backtracking sequence to heat up and cool down the keycard
@gator1984atcomcast Says:
Forget wheels. Wheels need roads. Use legs or just hopper.

12:31 Holy prediction
@AppliedCryogenics Says:
I know every crazy uncle says stuff like this, but industry will never abide a "forever-tire".
@me.ssiah0 Says:
Ok, so why don't we make car tires with this material while still using a suspension system?
@theadjuticator Says:
Unfortunately metal tire damage road lol
@CharlesIsabirye Says:
I wonder, how does tht bike tyre act up when u push the bike wheel above 40km/h... Will the tensile memory let u down?

why would u need bulletproof bike tires bro like where the hell are u going

And also Jim

FINALLY found ur channel Derek
@friedwartgurfinkel-buchsen6434 Says:
wow finally i can get bulletproof wheels for my bicycle
nearly every week it got shot at least once on my way to work
that a problem of the past now, so glad

is this how memory matresses works lol

why am i seeing footprints on the so called mars
@nmon9402 Says:
The wheel was on shark tank,, they were trying to raise funds for bycicle tire that cost $1200 each

This is what America should be concentrating on not colonising Greenland and stealing Venezuela oil.
@davidjuansaputra31 Says:
But how u make the "original" shape. Like, the real original shape of it is an aloy, but we "bending" it to a spring and other shape. How can a spring being the original shape?
@Julz-cj6zh Says:
Btw this was patented in. 2001 and pat expired 2021 so have fun
