Retrieve ball-bearings from the liquid with a magnet outside the jar. This is a messy activity to clear away, especially if many ball bearings are allowed to fall and must then be retrieved.

Get Price2008-10-27u2002·u2002The falling ball viscometer is well-suited for measuring the viscosity of a fluid, and the method has been stated in international standards. 4,5 In the international standards, the method differs from the principle described in Refs. 1–3. The standards describe an inclined-tube method in which the tube for the falling ball was inclined at 10 ...
