Smash Your Hand

This demonstration involves placing a heavy object, such as a lead block, a steel plate, or a brick, on your hand and then hitting it with a hammer. The principle of inertia is at play here; the heavy object's mass resists acceleration, meaning the force of the hammer blow is absorbed by the object and not transmitted to your hand. This dramatic demonstration helps illustrate Newton's first law of motion, showing how inertia can protect your hand from the impact, and emphasizes the concept of distributed force.
