Submarines are the central theme of the July issue of Popular Mechanics. By studying the report on the secrets of the submarine base carved out of the Crimean Mountains, readers will learn why the era of military submarines is nearing its end and reasons why people take condensed air under water.
This July the world will commemorate 40 years since the “giant leap for mankind" – the first moon landing by U.S. astronauts. The article dedicated to that historic event is accompanied by other material in the same issue describing Soviet projects designed to conquer the moon that were never brought to fruition.
Swords forged specially for PM were finally completed. They demonstrate their prowess in fencing, cutting heads of cabbage and piercing automobile doors. Lovers of weaponry-related themes will also read about vacuum bombs and fishing with bow and arrow.
Among the issue’s other themes: robot matrimonial games, new automatic transmission designs, supermarket shopping carts of the future and aerodynamic tests of automobiles. In the “adrenaline" section, readers will find accounts of swooping, one of the most difficult and dangerous forms of parachuting – as well as material on the round-the-world yachting race for the Jules Verne prize.
