Wolverine, Marvel‘s most popular character, has retractable bone claws plated in adamantium, a fictional metal that is supposedly indestructible. The Hydraulic Press Channel tried to crush this unique material.
They first tried with a small ball of adamantium. The ball ended up embed into the block of steel, but nothing happened to it.
After that, they invited Wolverine himself to put his own claws under the press. The result was outstanding.
Of course, the video is faked. In fact, it’s an original publicity for the movie Logan.
