DescriptionAnt on a rubber rope animation discrete.gif
English: An ant (blue dot) is crawling on a stretchable rope (initially 4 cm long) at a constant speed of 1 cm/s. After each second, the rope instantaneously and uniformly stretches by 2 cm. No matter how long the rope is initially, how frequently it stretches, or by how much at a time, the ant will eventually reach the end.
