A fascinating and incredibly unique time-keeping device, this piece features an elegantly shaped hourglass sand timer suspended in a glass cylinder filled with blue liquid. When you turn the timer to start the countdown, the hourglass will rise to the top amidst a buoyant bed of bubbles, as the sand begins its descent from the upper tier of the hourglass to the lower. The mulitple layers of glass and the shifting sand create interesting reflections and visual distortions within the timer - watching time pass has never been this entertaining! The timer will go for a full five-minutes; just flip it back over to start anew! Makes an excellent gift for anyone with unique taste, and makes an excellent office desk centerpiece or conversation starter.
