If you cannot enjoy your morning coffee leisurely in a seated position, you may want to consider switching to lattes to avoid spillage. Coffees swill easily spill. How many shirts were spoiled and even pants for that matter. They are better enjoyed when sitting down.
If you are always in hurry in taking your morning sip, you might want to shift-sipping your coffee. Lattes will less likely to spill on you compared to other brews.
According to Los Angeles Times, authors of a study published in the journal Physics of Fluid said, the layers of foamy substance in lattes serve to prevent them from spilling over or dripping through the sipping orifice of a travel cup. The idea may have also its uses on the hauling of oil and gas.
“While I was studying for my Ph.D. in the south of France, we were in a pub, and we noticed that when we were carrying a pint of Guinness, which is a very foamy beer, the sloshing almost didn’t happen at all,” study lead author Alban Sauret, who is currently a researcher at the French National Center for Scientific Research (CNRS),said in a press release. “The potential applications are much bigger than just beer.”.
A mechanical engineer at New York University Polytechnic School of Engineering, Emilie Dressaire, who co-authored the research, revealed that it was a drive-through attendant who gave her the idea.The attendant gave her the latte she wanted along with the stopper she requested to prevent the drink from spilling on her, though, from his experience, few customers spilled their drinks.
“That got me thinking, ‘Well, what he means by that?'” she told the Times. “And then I realized what he meant was the foam of the latte was going to prevent spillage while I was driving around.”
If they can apply the principle of their work to gas and oil transportation, they could make the hauling business safer and more efficient.
“When you think about your cup of coffee, you can see that the motion can get pretty violent,” Dressaire said. “Imagine the same thing but at a much larger scale… you’re going to generate forces against the walls of the container that are going to be really high every time the ship hits a wave. So the motion of the liquid inside the ship can lead to structural damage and it can also can disturb the motion of the ship itself.”
