Secrets of… safe transport of coffee!!

The secrets… not brown, but was not poured coffee, in an effort to protect the world friends, of the frustration often feel when they see it being poured during transport, reveal……
American scientists,How you can avoid the fatal;

According to researchers at the University of California – Santa Barbara:

• The first thing to do, when it begins with a coffee in hand, to walk slowly and do not accelerate too.
• also, must taking care to leave a certain safety distance between the brown surface and the rim of the cup. This distance should be at least, one eighth of the diameter of the cup or around one hundredth.
• Equally important is, To anyone looking at coffee time carrying him and not… looking towards.

Scientists, They came to these conclusions - secure transport regulations coffee, using the equations of fluid dynamics.

analyzed, so moving the liquid coffee inside the cup in relation to human movement that keeps.Through a complex interaction accelerations, moments and forces, with respect to the shape of the cup and how full is, shows the final result: ie whether the coffee will reach its destination unharmed or spilled.

The researchers put a volunteer in the lab, to come and go with a full cup of coffee in his hand, at different speeds, either looking coffee, or looking away.

A camera continuously recorded the movement of the human and the trajectory of the cup, while a tiny sensor inside the cup watched the coffee movement and when he poured out.

According to scientists, movement back and forth of a liquid in a container having an own natural frequency, which depends on the size of the container.

The researchers found that usually, coffee cups manufactured by the companies, produce natural frequencies motion of fluids (as coffee), which happens to match the frequencies of the leg movements during walking.

This means that when one walks with coffee in hand, makes the liquid inside the cup to swing to and fro.

Even the slightest irregularity in the gait-or some other interference- enhances coffee oscillations into the mug, increasing the likelihood that spill.
