build your own boats
Science & Technology
There’s nothing nicer than messing about in boats – and these eight mini models of real-size craft (and the odd fish!) just add to the fun. And they only use easily available bits and pieces, plus things you usually recycle. Simple step-by-step instructions and clear photographs show you how to make a catamaran from two cans and a propeller, a jet-boat from a plastic bottle and a fizzy mix, a quirky pond skater, a deep-diving submarine, and more.
• Incredible facts explaining how the these vehicles are built and work.
• Easy-to-follow guides to make a whole range of working models.
• Great resource for school projects using simple household items.
