A plan has been launched to win £50m of National Lottery cash for the Swindon branch of the Science Museum to turn it into a centre of excellence.
The Inspired plan is to build a huge centre, showcasing many items that cannot find room at the major branch of the museum in South Kensington.
The Swindon branch already has more than 18,000 objects.
These include space rockets, fire engines, bicycles, scientific equipment and aircraft at the Wiltshire museum.
Director Martin Earwicker said: "Inspired will not only provide a brand new type of museum with access to previously unseen inventions and innovations, it will also inspire future generations of scientists to step up to the challenges of our world."
The Inspired project had been designed with three aims, he added - to deliver serious fun on a spectacular scale, to inspire ordinary people to do extraordinary things and to unleash the genius in everyone.
