The British government has come up with an innovative solution to the problem of school children's waning interest in science: teach them about how bombs are made. More specifically, science teachers are being encouraged to show students how to make the sort of movement-triggered tilt switches that were used on the bombs that killed nearly two hundred people in Bali last month. Other suggestions for sparking student interest include analyzing an actual murder site for blood samples and studying how cars crumple on impact by simulating crashes.
