Prime Sieve

This world demonstrates the Sieve of Eratosthenes, which is a method for finding prime numbers.

Here's how it works: Each time you click on the "Click Me" button, a new arrow will be created. The first arrow will cross out every second number (except for the number 2). The next arrow will cross out every third number (except for the number 3). After you have clicked on the arrow many times, the only numbers left are numbers that are not divisible by 2, 3, 4, 5, etc. That is, they are prime numbers.
