About This Product
The apparatus is filled with water and a cut shoot is sealed into the stopper on the end tube, while the open end of the capillary dips into a beaker of water. As the shoot takes up water, an air bubble moves along the capillary, and opening the stopcock lets water in from the reservoir to reset the bubble. Conditions around the shoot can be varied to compare rates.
