Break a stick with inertia
Secure a small stick 18 to 20 cm in length. If no other stick is available a lead pencil will do. Fold a newspaper and place it near the edge of a table. Place the stick under the newspaper on the table and let about half the stick extend over the edge. Strike the stick a sharp blow with another. Inertia should cause the one on the table to break in two parts.
