Turn over the Slanted Ramp Timer and watch the liquid drip down the ramp. It takes two to three minutes (depending on room temperature) to completely empty into the lower portion.
Great prop to keep on a science table for the children to tip, turn and watch as the liquid spirals down. Spiral timer can also be used for teacher or child stress/relaxation, quiet time toy, refocusing prop, anxiety prop, or a timer.
Two different choices: blue base with green and blue liquid OR pink base with pink and blue liquid.
