I have just got back from running a wonderful Tinkering workshop at Calke Abbey. We had a 'back to the future' machine made, a sound collector, planes and who can build the highest free standing tower. 7ft won the first days record. Bring it on for tomorrow.
Build a tower to be smashed down by the....
medieval pulley system and wrecking ball.
Last but not least the wonderfully random sound magnifier, with quality buttons for all sorts of effects.
