Oxford Electric Bell....

Good night to all...!

Today we are going to read about the Oxford electric bell...

Okay....what's the different with it..??? it's a bell only, isn't it??

Yes...ofcourse it is just a bell but the thing which made it to stand out is that there is a battery which powers it for 177+ years and still the battery has not drained out….!!!

Can you believe it??

But it’s true…!

Nobody knows what the mystery the battery is made of. So let me call this bell as experiment here…

The experiment is currently kept at the University of Oxford's Clarendon Library.

The experiment consists of two brass bells, each positioned beneath a dry pile (an early form of battery). A metal ball approximately 4 mm in diameter suspended between the piles, which rings the bells alternately due to electrostatic force.

As the ball touches one bell, it is charged by one pile, and then electromagnetically repelled, being attracted to the other bell. On hitting the other bell, the process repeats.

Oops…confusing…it is being hard for us to even understand the concept of it’s working but those people made it to work….

The bell is ringing at 2 Hz; it means you can hear 2 rings each second.

For last 177 years, it's made a whopping 10,911,456,000+ strikes against those bells, and still showing no chances of dying out anytime soon.

It was built by Watkin and Hill in 1825, an instrument-making firm in London, and purchased by Robert Walker, a professor at Oxford.

In 1840, he set it ringing. Today the bell is still ringing…

Hard to believe….isn’t it?

Watkin and Hill left no record of what the piles (battery) were made of. Scientists are eager to find out just how long the mystery battery can go, and then open it up and find out what it's made of, but the whole thing is a bit of a waiting game.

Whatever Watkin and Hill used to make the batteries, the device has extraordinary stamina….!!!!

Guinness Book of World Records called the bell's dry piles the "world's most durable battery"…!!
