In this demonstration, learners observe as a bottle is placed on a table with wooden hoop balanced on top and a pencil balanced on top of the hoop. The demonstrator will quickly grab the wooden hoop in an angle downwards so that the pencil lands in the bottle. After demonstrating the trick, learners can try it themselves. Use this activity to demonstrate gravity and inertia. [Activity is publicly available through a web crawler capture on Archive.org.]
