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.

hi! I have theory about somthing interestig of evolution
I like how excited they all are
36km on the moon was very impressive I didn't know they drove as much, do it by bicycle and if not enough by foot and then imagine that on another "planet"
23:19 : But have we enough titanium and Nickel to do all of these ? (But the positive point it that is economize caoutchouc/petrol and other mater, we just need to find the good proportion)
25:20 : "lifetime razor" -> get 100 free blade. weird definition of lifetime.
Reinvented the [tire].
Sometimes science is just sexy. This is one of the most amazing things ever.
So, when can I buy this tires for my bike?
Riding over that bed of nails would have had the same result if you rode across it with tubeless tires and sealant. Still inflated.
…just saying.
First steps to ferro fibrous muscles for mechs! Woooooo BattleTech is real! 😀
I felt HIGHLY suspicious at 12:46 when you spent only the least visible frames proving the weight lifting and rock splitting phenomena. It came across in the moment like salesmanship, like using very selective success to oversell a product. Anyways, I trust your stuff generally so there may be reasonable explanation.
As an Austinite, Austenite really resonated with me.
I’ll see myself out.
Is Henson a ‘woke’ company?
PROSTHETICS PEOPLE!!! Synthetic muscles!
very cool demo!!!
Dude said we need metal mesh airliner tires. How you going to stop aggressively?
the biggest Liars in the Universe.. Nazi NASA
"This replaces all the hydraulics"
You hear that? We got mechanical muscles. You know what mechanic muscles mean? Simple mech legs
IT'S MECHA TIME
So.. elastishity?
This is also used in the Zepto device for difficult cataract surgeries!
23:30 Fact, NASA approves DeWALT tools !
I misread the title as "How NASCAR Reinvented The Wheel". This is good too.
wild.. like Wakandan tech stuff
0:55
To all the so called scientists etc ,,, NASA have NOT reinvented the wheel .. All they have done is alter something that already exists.
I wonder though, did American scientist more familiar with metric or imperial?
how far are we getting things like car tires on a consumer level?? (even bike tires)
Hey Derek Muller, remember when you said Elon Musk was "better" than us? Why have you since shut your stupid mouth about him if that was true? You kept your yap quiet about musk for at least 5 years so whats going on, bro?
my kind of stuff
Why weren't the improved moon rover style wheels used on any of the mars rovers? Nitinol is not that new and Perseverence was rather recent but it still uses the same style of wheels as Spirit.
Just out of curiosity, no pun intended, could fiber glass be a potential candidate for tires while adhering to the stretch parameters needed?
Dang. That's bad when a metal had a better memory than me.
Nasa should cure cancer , not make random metals NGL
Airless basketballs, now airless wheels… what is next airless breathing?
u are donkey time !!! nuclear plasma technology it's here bro!!! KESHE ITS HERE
So when can I get these flat-proof tires for my bike that last a lifetime and can be insured against theft? Because no matter their price they WILL be stolen in 3… 2…. Wait, wheres my bike?!
Holy crap man, thank you so much for this video. The history, the details, the science. Great stuff!
What does he say at 15:39? I hear "That peening is pooning."
I want some shoes!
These would also make the best prosthetic feet!
I do not like your ad for the shaver, because it is a scam. I have a Fusion 5 shaver. That is also in aluminium so it will last for the rest of my life. For my shaver, 8 knives lasts for 2 years. The shaver in the ad needs 100 knives for every 2 years. It says so on their webpage. So the shaver in your ad has bad quality and is bad for the enviroment. My dad has a plastic shaver, it has lasted for 40 years so far. No need for your scam you little scammer.
couldn't this technically be used for robotics? if you could rapidly heat and cool a bunch of these wires you could create a muscle system.
Surely next level has to be 3 concentric wheels around axle for super suspension.
Beat ads on YouTube by muting them, closing your eyes, count to 7, viola 😃
