London with Kids - The Best TOURS & THINGS TO DO
"A futuristic museum that is spread across seven floors of interactive and entertaining exhibits and explores everything from space travel to the Industrial Revolution. There’s something here for kids of all ages, including toddlers. Highlights include the giant telescope in the Exploring Space section, flying machines in the Flight Gallery – from hot air balloons to vintage planes, and the IMAX cinema shows on deep space and the underwater world."
