Ans-: The magician sometimes combines two immiscible solution in a beaker (in a chemical magic show) and draws out a seemingly endless rope of nylon. This "nylon rope trick" is based on the likelihood that reactive molecules in two immiscible layers will come together at the interface, where the product will appear. When the product is a nylon polymer (which forms strong fibers), it can be pulled from the interface like a rope. If the rope is slowly drawn out, the nylon that is removed is continually replenished at the interface until one of the reactants is used up.
