THOUSANDS of people flocked to Bradford's National Media Museum for fiendish family fun this weekend, as the Horrible Science festival, running throughout half-term, opened its doors to the public.

The best-selling series of children's books and resources is celebrating its 20th anniversary this year, and 2016 marks the first time the activities have come to the museum.

Events on offer include the Microscopic Monsters, where children use microscopes to investigate creatures invisible to the naked eye, Spectacular Specs, where visitors create their own 3-D glasses to explore the world in fantastic colour, and Eerie Eyeball Dissection, where guests get up close and personal as scientists dissect a real sheep's eyeball to explain the incredible science behind the eye.

Elaine Richmond, explainer team leader for the events, said: "The week is very family-orientated, with activities to suit both children and adults.

"All the activities have proved very popular so far, and we had around 1,600 people take part on Saturday alone, which made a very strong start to the week.

"We will also have the Horrible Science illustrator Tony De Saulles here, who will be bringing science to life with his live drawing workshops."
