This video illustrates how a simple child’s toy can defy everything we think we know about gravity. Discover how spinning the wheel of the gyroscope enables it to stand up on its own, balance on a piece of string, and generally appear to levitate – all due to the effects of angular momentum. This video also refers to the advanced application of gyroscopes for stability and navigation on the Mars Rover, aeroplanes, helicopters, ships, and robots. There’s also an article on gyroscopes coming up in issue three so don’t miss it.
