Toilets and other great inventions

Adam Hart-Davis is passionate about toilets, and about all sorts of other inventions, from early clocks to Pringle guns and speaking machines. This event will be packed with demonstrations, many of them to do with time, and may include falling tomatoes, whirling tea cups, and bursting balloons.
