Researchers decided to use a high-speed camera to capture what occurs while opening a swing-top bottle of beer. They found that the sound emitted by opening a pressurized bottle with a swing-top lid ...

For the first time, physicists have captured direct images of 'second sound,' the movement of heat sloshing back and forth within a superfluid. The results will expand scientists' understanding of ...

In most materials, heat prefers to scatter. If left alone, a hotspot will gradually fade as it warms its surroundings. But in rare states of matter, heat can behave as a wave, moving back and forth ...

DEAR CAR TALK: We're having a problem with our 2008 Honda Fit. The car runs OK, but there is a sloshing noise when we drive. It sounds like some liquid is moving back and forth up front somewhere. Any ...

The motion of the bottle also causes the liquid to slosh, and the group's high-speed recordings captured this wave within the bottleneck. Additionally, they noticed that the momentum transfer of the ...
