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!
