Man Makes Emergency Lamp Using Water Bottle, Milk & Smartphone After Super Typhoon Hits Japan

As we reported yesterday, Japan was hit by Typhoon Hagibis, which is the worst typhoon to mow over the country in the past 60 years. The typhoon made landfall at about 7 pm local time yesterday (12 October).

Just like the previous storm that hit Japan last month, which caused almost a million people to lose power, many faced power outages after the passing of Typhoon Hagibis.

The power outage has prompted a Japanese Twitter user to share a cheap and easy solution to create an emergency light source in the house. All that is required include a water bottle, some milk and a smartphone.

At first, he only used a bottle that contained plain water, and the brightness was not strong enough.

However, after adding a bit of milk, the light from the bottle became stronger and brighter. He said,

“If you mix a little milk into the water, the brightness will be different. Try this if there is a power failure after the typhoon.”

The phenomenon behind this is called the Tyndall Effect. According to ThoughtCo, it is the scattering light as it passes through a colloid. Individual particles scatter and reflect the light, making it more visible.

最近よく見るペットボトルライト、中身に水だけじゃなくて牛乳をちょっと混ぜてあげると明るさが段違いになるんだよね。（1枚目は水だけ、2枚目は水と牛乳）

This is a great idea to be used by anyone, especially Malaysians, as some of us tend to face power outages regularly throughout the year. It is true what they say; necessity is the mother of innovation.
