Solution, FAQ and sources

Solution

One germ becomes two after the first minute. From then on, a jar that started with one germ and a jar that started with two look exactly the same — the second is just one minute ahead.

The first jar fills at 60 minutes, so the second fills at **59 minutes**.

About this puzzle

A single germ in a jar splits into two after one minute, and every germ keeps splitting in two each minute. Starting from one germ, the jar is full after exactly an hour. How many minutes would it take if you started with two germs?
