Fun was had with science at Queen Elizabeth Olympic Park as it played host to the Spark Festival.
The two day event saw nearly 3,000 people take part in 20 different activities, all themed around engineering and science.
The event was organised by University College London, who will have a campus in the park from 2019.
Festival coordinator Philippa Richardson said: “It went really well, and the weather on Monday didn’t stop families having fun.
“You could learn about nano technology using Lego or watch a 3D printer print a 3D printer.
“There was even the chance to sit inside a Formula 1 car and change the tyres, which got quite competitive.”
The university’s brass band, Dat Brass, entertained the crowd, while children could have their faces painted.
The event proved to be an inspiration for the young visitors as the festival was run by a number of university students, who were keen to share their passion and knowledge for science.
