For example, wire is bent to form a model car complete with wheels and – in the most sophisticated versions – front wheels that can be turned by the stick you push it with. Or an old bicycle wheel or tyre becomes a hoop to push along the path. Or a few polythene bags and some wire can be tightly wrapped to produce a surprisingly springy football so you can play a game in the silt of your flood-washed village.
But perhaps I was most impressed this week by this little chap who with just damp clay from the stream beside his church had built this incredible model of a big 4×4. Eventually it was complete with spare tyre at the rear, luggage rack on the roof, and (made from grass) the giant whip aerial that is a ‘must have’ for the ubiquitous white NGO Land Cruisers that speed past him every day.
