A light bulb is powered in series with a coil of thin copper wire. Initially the coil is at room temperature and, because of its resistance, the bulb is only faintly lit. When the coil is immersed in liquid nitrogen, its resistance is quickly and substantially reduced causing the bulb to glow very brightly.

Use power supply instead of batteries.
