The Patchwork Bike

When you live at the edge of the no-go desert, you need to make your own fun. That’s when you and your brothers get inventive and build a bike from scratch, using everyday items like an old milk pot (maybe Mum is using it, maybe not), a bent bucket seat, and bashed tin-can handles. The end result is a spectacular bike, perfect for going bumpetty bump over the sand hills, past your fed-up mum, and right through your mud-for-walls home.

The Better Tree Fort

Let’s build a tree fort,” Russell says to his dad when they move into a house with a big maple tree in the backyard. His dad doesn’t know much about building, but he gamely follows Russell’s plan. Several trips to the lumber store later, the tree fort is done. There is no slide, balcony or skylight like Russell imagined, but it is perfect ― right up until he notices another tree fort going up three houses over.

Earth-Friendly Buildings, Bridges and More

This dynamic title takes the form of Corry’s scrapbook. It’s a dazzling collection of postcards, brochures and other memorabilia documenting Corry’s research into green design. Kid-friendly language explains the engineering behind some of the planet’s most cutting edge towers, bridges, tunnels, domes, dams, dikes, locks and levees. These structures include the Vizcaya Bridge in Spain, where gondolas transport cars over the Nervion River, and the Channel tunnel, where trains speed between England and France in just 35 minutes.
