Description: Watching this video can release the pressure of life and work! Use a shredder to test the hardness of the tortoise shell! A few very interesting shredder experiments! Do not imitate! Non-professional operation may be unsafe! My friend, I didn't kill the tortoise, I just bought a tortoise shell of the same size to test the hardness!
