The tubes can be filled with different fluids and by using the magnet bar, steel balls can be dropped at the same time into each fluid filled tube. The clear tubes allow the observer to see which balls fall through the fluid faster and which ones fall slower. The slower the steel ball falls in the fluid, the greater the viscosity of the fluid.
