Tube speed of the bubble, 30 per case, A bubble in each tube rises at a constant speed that depends on the type of fluid, the angle at which the tube is inclined, and to some extent, the temperature.This set provides students with practice setting up experiments and graphing data.
Racing Rings consists of three rods one each of copper, aluminum and PVC, Ring magnet is dropped down the PVC rod, it falls unobstructed, Two metal rods create an induced magnetic field to that adds resistance to the rings travel, metals are different, they fall at different rates
