The molecules and atoms vibrate at higher temperatures and begin to push apart from each other. This phenomenon is known as thermal expansion. Simply heat the brass ball for two minutes. This will cause the ball to expand; hence it will not fit through the ring. When the ball cools down, it will once again fit smoothly through the ring. Great for the classroom or the home laboratory!
