Following the success of the Cracking Contraptions Manual, Wallace has pulled the dust sheets off a further 20 of his ingenious inventions, from the Mind Manipulation-O-Matic and Bun Vac 6000 (Curse of the Were Rabbit) to the Jumbo Generator and Steam Chair (World of Inventions). Cracking Contraptions 2 again features superbly detailed cutaway drawings by Graham Bleathman, informative technical descriptions and color photographs throughout. This time, as well as reprising his role as editor, Wallace plans to take control of the entire print production process.
