When the glitter lamp is plugged in, the light bulb heats up the interior glitter filled liquid, causing it to swirl around the cylinder. What's more, the liquid is a bright pink colour, adding even more to the groovy retro effect. This is a classic lamp that's been popular for decades, and is sure to be so in the years to come.
