THE organisers of a festival of engineering are announcing a line-up change after the man due to front the event was forced to pull out.

Steve Mould, television science presenter, founder of ‘Festival of the Spoken Nerd’ and of the Guerrilla Science Outreach Group, will now host Riveting Stuff.

The event, which celebrates the region’s engineering heritage, takes place at Tees Barrage near Stockton's over the weekend.

Mr Mould will replace the previously advertised appearance of Jem Stansfield who is unavailable due to unforeseen circumstances.

Tomorrow (Saturday), between 10am and 5pm, and on Sunday, between 11am and 5pm, a number of exhibitions and demonstrations will be held where visitors can take part in a raft or bridge-building challenge.

There is also a chance to watch a new documentary on the history of local firm Head Wrightson, lift and move weights, enjoy a display of images, models and vehicles celebrating the engineering past, build a boat and race it in the International White Water Course.
