Take a closer look at the world around you. Using revolutionary high speed HD technology that can slow the action down to 100,000 frames per second, this programme reveals the physics and science behind the technology. See how revolutionary high-speed, high-definition video is used to analyse pit crew performances down to fractions of a second for rally car racing, a sport where races are commonly won by tenths of a second. See how explosives researchers use high-speed cameras to capture the fire size of flash grenades. Then, take a look at a beer brewer that uses high-tech video monitoring systems to analyse the high-speed production line in slow motion so it can investigate the source of the last costly shutdown.
