Watch the liquid drain from a container as time runs out.
The Liquid Timer displays a glass container filled with blue liquid that drains smoothly as the countdown runs. The water surface ripples gently and tiny bubbles float upward, creating a mesmerising, calming effect. Measurement lines on the side give an extra visual reference, and the percentage display at the top shows exactly how much time remains.
