Go with the flow

Yesterday we learnt about flow rate and viscosity.  In order to demonstrate the flow rate of a variety of fluids without making a huge mess you can just do this quick demo.  Place a marble inside a test tube and fill it with a fluid and cap it off with a cork and tape it down.  Repeat for a variety of fluids.  Then race them!  It took months for the marble in the molasses to get to the bottom!
