Professor Branestawm's Treasure

When it was a case of inventing an unspillable teacup, or a collapsible-cum expandable house, or a liquid carpet to be applied with a brush, or a machine for peeling and pipping grabes, a bomb or a fire alarm, Professor Branestawm was the man for the job. This marvellously funny book is for nine - twelve-year-olds, particularly boys.
