Tablet hardness testing

Tablet hardness testing is like giving a little squeeze to a piece of candy to see how hard it is.

Tablets are like little candies that have medicine or vitamins inside of them. We need to test how hard they are because if they're too soft, they might break apart too easily and not work right. But if they're too hard, they might not break apart at all and not work right either.

So, we use a machine called a hardness tester to give the tablets a little squeeze and see how much force it takes to break them apart. We record the results to make sure all the tablets are the same hardness and work the way they're supposed to. It's like checking to make sure all the candies in a bag are the same hardness and taste good.
