Petrol Powered Machines | Szydlo's At Home Science

Andrew shows how many of the tools that make our life easier are powered by engines, often internal combustion engines. Starting with a demonstration of a manual sewing machine, and the latest in fashionable North London face-wear, we are shown the workings of both a petrol lawnmower and chainsaw.
