You could lose hours absorbed in this book! Styled rather like the revision books of school years, this is stuffed with loads of the questions that might have taken moments to answer when you were wearing short trousers or pigtails (or both), but now require a little more effort. Divided up into academic subjects, with a mixture of multiple choice, picture-based & direct from memory answers, this is a sure test for any ex-pupil. You'll probably discover, as we did, the answers section is spied embarrassingly often. Just don't leave this lying around or that know-it-all twelve year old will polish it off in an hour! Fantastic practice for your next pub quiz. ...

It was famously promoted by Rolf Harris at the end of the 60s & went on to sell over three million pieces. This re-launch is very close to the original with volume control, vibrating effects & now the ability to plug in to an MP3 player & play along with the songs. ...

This 11cm crazy mechanical creature zooms along underwater spinning randomly & bouncing off any obstacle it meets. It has to be seen in action to appreciate how amusing it really is.
