Want to know about the first text message ever sent?
These are just some of the fascinating facts chosen by a group of teachers to inspire youngsters to pick a career in science and engineering.
They are launching a “guerilla science” campaign, posting up a range of amazing and amusing facts in parks, chippies and skate parks.
The project has been organised with The Big Bang UK Young Scientists and Engineers Fair to be held at Birmingham NEC on March 13-16 next year.
Vasu Krishnaswamy from London’s Stanmore College has been involved and says: “This is a fun and different way to remind pupils that science and engineering are part of our lives – from the games they play on their iPhone, to the bus they get on each day.
“We hope to capture young people’s imaginations – the first step to really engaging in and enjoying a subject.”
