Vernon Bright and the End of the World

Puffin ISBN 0141305878

When Mister Hardman (the PE teacher who was thrown out of the Royal Marines for excessive cruelty) challenges Bright to a weight lifting contest, brawn against brain, he has no idea what he's started.
Because if Bright can't make himself stronger, he'll have to make the weights lighter and to do that, he has to invent a machine that will defy the force of gravity.
And when the machine goes out of control, well, it's not the end of the world. It's worse than that!

The 2Steves say... "In The First Men In The Moon by HG Wells ( Pub.1901), an inventor called Cavor invents a substance (which he modestly calls 'Cavorite').
With his partner Bedford, he builds a capsule out of Cavorite and goes to the moon. The reason Wells was able to get away with this hare-brained idea is that back then, nobody knew exactly what gravity was.
The nice thing is, they still don't, which is why we were able to get away with this story."

Other people say... "Some great one-liners! This book is an entertaining romp with an educational edge and bags of boy-appeal."
