How a Pendulum watch works?
*What is a pendulum?*
A pendulum is a rod hanging vertically from its top end (or a weight called a bob hanging from a string) that swings from side to side due to the force of gravity. As Italian scientist Galileo Galilei (1564тАУ1642) discovered, the clever thing about a pendulum is that it always takes the same amount of time to make one complete swing.
A pendulum works by converting energy back and forth, a bit like a rollercoaster ride. When the bob is highest (furthest from the ground), it has maximum stored energy (potential energy). … So as the bob swings (oscillates) back and forth, it repeatedly switches its energy back and forth between potential and kinetic.
If there were no friction or drag (air resistance), a pendulum would keep on moving forever. In reality, each swing sees friction and drag steal a bit more energy from the pendulum and it gradually comes to a halt. But even as it slows down, it keeps time. It doesn’t climb as far, but it covers the shorter distance more slowlyтАФso it actually takes exactly the same tiwatc swing. This handy ability (technically called isochronism, which just means “equal amounts of time”) is what makes a pendulum so useful for timekeeping.

Why water is sprinkled around the plate before taking food in Hindu tradition !*
Scientifically It has been done to keep insects away from food while eating. Because in olden days, people use to eat in leafs and by sitting on the ground.

Hibiscus tea can be made by steeping hibiscus flowers in boiling water for five minutes. It can be consumed hot or cold and has a tart taste that is often sweetened with honey or flavored with lime.
Hibiscus tea is an herbal tea thatтАЩs made by steeping parts of the hibiscus plant in boiling water. Hibiscus tea is rich in powerful antioxidants and may therefore help prevent damage and disease caused by the buildup of free radicals.
One of the most impressive and well-known benefits of hibiscus tea is that it may lower blood pressure.
Test-tube studies have found that hibiscus extract reduces the growth and spread of plasma, mouth, prostate and stomach cancer cells.
