00:00If you fired a tank round at a row of phone books, they would be instantly shredded into confetti.
00:06Even with 10 rows of phone books, the round would still tear through them without a problem,
00:12traveling around 5,000 feet per second when it came out the other side.
00:17You would actually need a wall of over 1,700 phone books,
00:21stacked almost 300 feet thick, just to stop a single shot.
00:26But even then, the whole thing would probably go up in flames.
