Sand powered acrobat automaton mechanism

Michael Start from The House of Automata sent along this nice video of a sand-powered acrobat automaton.

From the video description:

Made for a National Museum. The Acrobat is a copy of a Victorian example but strongly made and with a Perspex back to allow the public to operate it and inspect the mechanism. Note the use of a suspended glass bearing as per the original.

[ Thanks Michael! ]
