What! This bubble has lasted for 465 days

Blowing soap bubbles will never fail to delight one’s inner child, regardless of how quickly they burst.

We have some good news for those who always seem to feel disappointed due to this ephemeral nature of bubbles. According to a new paper published in Physical Review Fluids , French physicists have created “everlasting bubbles” using plastic particles, glycerol, and water.

They even managed to build a bubble that survived for a whopping 465 days.

In contrast to soap bubbles, the new bubbles can last more than a year before they pop, reported the scientists.

Rather than soap and water, the bubbles are made from water, microparticles of plastic, and a viscous, clear liquid called glycerol. The trio of ingredients prevents factors that normally quickly deflate bubbles.

Normally, the liquid in a soap bubble sinks to the bottom and leaves a thin film at the top, which can easily rupture. Furthermore, evaporation saps bubbles’ strength. Plastic particles cling to water in the everlasting bubbles, maintaining the thickness of the film. The glycerol in the air blocks evaporation by absorbing moisture.

We were amazed when the bubble didn’t rupture even after days, says Michael Baudoin of the Université de Lille in France.

In order to gauge how long the bubbles would last, he and his colleagues watched them closely. They waited and waited, and waited. The longest-lived bubble ever created under normal atmospheric conditions lasted 465 days before it burst.

Before it finally burst, that bubble turned slightly green, an indication of what finally caused it to pop. According to the team, microbes took residence in the bubble, weakening its structure.

Leif Ristroph, a professor at New York University who wasn’t involved in the study, says such anti-evaporation technology could be useful in medicine. Speaking to NBC he said, “I’m daydreaming here, but I could imagine it might be useful to ‘armor’ little droplets in aerosols and sprays to make them last longer in air…For example, some sort of medicine that’s administered by spraying and breathing in the aerosol.”

What monkey fled with a bag containing evidence in it: Read full story

The court, generally, considers a person who commit a crime and the one who destroys the evidence, as criminals in the eyes of law. But what if an animal destroys the evidence of a crime committed by a human.

In a peculiar incident in Rajasthan, a monkey fled away with the evidence collected by the police in a murder case. The stolen evidence included the murder weapon (a blood-stained knife).

The incident came to light when the police appeared before the court and they had to provide the evidence in the hearing.

The hearing was about the crime which took place in September 2016, in which a person named Shashikant Sharma died at a primary health center under Chandwaji police station. After the body was found, the deceased’s relatives blocked the Jaipur-Delhi highway, demanding an inquiry into the matter.

Following the investigation, the police had arrested Rahul Kandera and Mohanlal Kandera, residents of Chandwaji in relation to the murder. But, when the time came to produce the evidence related to the case, it was found that the police had no evidence with them because a monkey had stolen it from them.

In the court, the police said that the knife, which was the primary evidence, was also taken by the monkey. The cops informed that the evidence of the case was kept in a bag, which was being taken to the court.

The evidence bag contained the knife and 15 other important evidences. However, due to the lack of space in the malkhana, a bag full of evidence was kept under a tree, which led to the incident.
