When Malcolm Harradine used to front LnL, he always mentioned the machine for testing the containers had been invented by his father in law. Surely this is a different machine? Pa in law should have had it patented.
I remember him 'airing' the first silicone baking products - the first time I had ever seen them, and some of his cooking efforts were such a laugh as his fairycakes plopped out of the moulds !
