🎯 Загружено автоматически через бота: 🛑 Оригинал: 📺 Veritasium — @veritasium 📃 Оригинальное описание: NASA have made a wheel capable of withstanding tough Martian terrain, but just how indestructible is it? Head to 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. ▀▀▀ References: Steel Rod Footage - H.
