Prepare the buoy by attaching a small ball of plasticine to the end of a drinking straw. Press the underside of the ball on the table to make it flat. 
2. Take one or a few short video clips/photos of you/your group releasing the buoy into the measuring cylinder containing water. The video clips need not illustrate perfect execution of the experimental steps. 😊
