Editors Notes

Horrible Science fully embrace the icky side of science. Rather than it all being about boring facts and figures, they prefer to present kids with gory and highly fascinating details that are a bit unusual and not often found in stuffy text books. They attempt to emphasise the drama, excitement and wonder of science to fully engage kids and get them passionate about the subject.

They have sold over 4 million books in the UK alone, with them being available in 24 different countries.
