The essays on cultural equivalence and the Guardian's strange love affair with Islamic extremism are, apparently, going down well. Heap big traffic. But I think we'll have something lighter today. A frivolous interlude. First up, an homage to the jet pack, complete with video (courtesy of Wired Science).
More on rocket belts, aerocycles and other magnificent cold war devices can be found at the U.S. Army Transportation Museum. Readers eager to build their own jet pack can buy detailed blueprints here. The equipment is, we're assured, "fully controllable."
For readers who aren't so sure about meddling with large amounts of high grade gasoline or superheated steam, here's a less hazardous aeronautical project, involving flies, glue and matchsticks.
Research funding always welcome.
