When the first marble hits the other marbles going at a slow rate the rest of the marbles go at a fast rate, because oppostie magnets do not stick together so when the the first marble hits the other three marbles lined up they arn't made to go together so they push off of each with a great force pushinjg the other marbles and ultimately causing a chain reaction to happen causing the rest of the marbles to go faster than the first marble that we pushed.
