Turn over the Ramp/Drip Timer and watch the liquid slide and drip down. 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.
Ramp & Drip Timer can also be used for teacher or child stress/relaxation, quiet time toy, refocusing prop, anxiety prop, or a timer.
The blue liquid does drip slower than the red liquid, so they do not complete the cycle at the same time.
