David Leigh from the University of Edinburgh and colleagues from Italy and the Netherlands have made a rotaxane - a molecular ring threaded on a bar - and applied a hy-drogen bonding 'brake' to stop the ring spinning round the axle. Adding methanol disrupts the hydrogen bond system and lets the brake off - allowing the wheel to spin
