Ring of periods

Imagine you have a magic ring that can tell you how many times something happens. This ring is called the "Ring of Periods."

Let's say you want to know how many times a bird flaps its wings in a minute. You would set the ring to one minute, and every time the bird flaps its wings, you would press a button on the ring. At the end of the minute, the ring would tell you how many times the bird flapped its wings.

But the Ring of Periods can be used for other things too. You can use it to count how many times a clock ticks in an hour, how many times a person blinks in a minute, or even how many times a car engine cycles in a second.

Overall, the Ring of Periods is a tool that helps you count how often things happen over a certain amount of time.
