What makes an explosion? Of all the worlds’ technologies, few have experienced such a rapid rate of progress as explosives. In just 300 years we have advanced from gunpowder to the atomic bomb. During that time explosive power has increased more than 100,000 times. We travel to the heart of an explosion to understand just what makes an explosive force. We visit top-secret laboratories, and learn how terrorists have usurped the science of explosions to produce crude but deadly home made bombs. And we cast our eye to the future and reveal the reality behind the science-fiction dream of an all-powerful explosion... of antimatter. Around the world there are tens of billions of explosions every second; every time we start an engine or drive a car we rely on them. Without explosives, life as we know it would grind to a shuddering halt.
