Children learned how long Crossrail tunnels are during a Who Wants to be a Millionaire style quiz.
Project manager for the Thames Tunnel Gus Scott popped into Drew School in North Woolwich to oversee the competition as part of visits by Crossrail to local schools.
Apart from finding out that the Thames Tunnel drive is 2.6km long the children also learned that the main material boring machines are tunneling through is challk.
Assistant Headteacher Yolanda Musinguzi said: “Pupils found the session informative as well as inspiring. They have always wondered how tunnels were made under the water. Now they know. It has made them ask more questions about the field of engineering and many didn’t realise that engineering involved such a wide range of skills.”
