To celebrate 150 years of the tube, the London Transport Museum are hosting a month of family-friendly events. Including 'Steamy Science', demonstrations about how we keep London moving, including the joys of electricity, steam power and man power, and 'Tackling Tunnels', where kids can dig around and build in the sand box, as well as hear stories about the first underground railways in the world. Or craft a little character to ride the mini lifts and escalators created from paper in the 'Down With It' workshop. For ages 3-12.
