Video: Big boys' toys on show at Alexandra Palace model exhibition For swathes of today's society, entertainment tends to come in the form of an app or a box set. However, you may be reassurred to know there is still a dedicated band of leisure-seekers for whom there is no substitute for making something with your own hands. The London Model Engineering Exhibition, being held at Alexandra Palace in North London, is the place where such people, overwhelmingly male and middle-aged, come to find inspiration and show off their toys. Fully functioning model aircraft are the star turns, but first time flyers beware - contact your local model club for advice on how to avoid a pile of broken parts. The exhibition is open from 10 am to 5pm until Sunday 20th January.
