(PhysOrg.com) -- A team of scientists from France have worked out why teapots dribble at low flow rates, and how to stop them. The effect is called the "teapot effect", and solving it could finally put an end to tea stains ...
For 15 years, scientists have been baffled by the mysterious way water flows through the tiny passages of carbon nanotubes—pipes with walls that can be just one atom thick. The streams have confounded all theories of fluid ...
