Challenge your students' critical thinking skills with this intriguing demonstration that investigates the concepts of free-fall, inertia, and velocity. Drop two rods of unequal mass from the same height and show how they reach the ground at the same time. Then, ask students to predict the next outcome before launching the same rods downward to the ground simultaneously using a projectile launcher. Includes a launcher with rods of different masses and an instruction guide.
