Kibble balance

Okay kiddo, have you ever played with a seesaw or a balance beam? You know how we can weigh things by putting one heavy thing on one side and lighter things on the other side until they balance out?

Well, scientists have something called a kibble balance that is like a super fancy scale that can measure the weight of things really accurately. It's named after a scientist named Bryan Kibble who came up with the idea.

This special scale is used to measure the weight of really heavy things, like big crates full of stuff used in industries or even huge objects in space. It's important for scientists to know these weights really accurately so they can build things safely and make sure everything works properly.

The kibble balance works by using something called the Planck constant, which is a special number that helps measure weight super accurately. Scientists use lasers and electromagnetic fields to make sure the balance is perfect and can measure the weight of things down to tiny fractions of a gram.

So, the kibble balance is a special scale that helps scientists weigh really heavy things super accurately using lasers and the Planck constant. Cool, huh?
