A crank operates the leg and a counterweight ensures that the ball returns in time for the next kick.

A triangular cam controls a push rod which makes the jaw go up and down (and grin). The same rod operates 2 levers making the hands clap together.

Funky Joe hammers out a high speed rhythm whilst the cymbals crash and the bass drum pounds once every sixth beat. Hand crank model with four cams, three followers and numerous moving parts.

At home, on the sea, or at Henley, Steve gallantly skulls through the choppy waters, putting his back into it, whilst maintaining his calm and a regular stroke pattern. Hand crank operated using a pivot and three eccentric cams to create poetry in motion.

Effective way of showing that metal objects expand when heated and contract when cooled. A brass ball which will just fit through a brass ring at room temperature is heated and it expands. At its new larger size it cannot fit through. It is then placed on top of the ring and as it cools its diameter decreases until it drops through the hoop.
