Roll Up, Roll Up...see the Amazing Steam-Driven Marble Machine
With its brass flywheels and belt-drive, theres something of the Victorian fairground about this Marble Machine. Irresistibly fascinating, it features a cascade of 8 marbles that go spiralling down the tornado loop before being mechanically lifted back to the top again.
Its powered by a fully-functioning external combustion engine. Named after its inventor, the Stirling engine uses an external heat source to cause the inert air in the cylinder to expand and thus drive the piston. Side-lined for most of the 19th century - despite its power and efficiency - the Stirling is now enjoying something of a revival and is simply mesmerising to watch. Buy the pair ready-built or as an engrossing kit comprising 156 precision-engineered stainless steel and brass components.
