Step 1: Gather materials: A ball of twine, a laser pointer, and a can of tuna (for the discerning feline)
Step 2: Create a Playzone: Clear the living room floor of any breakable objects, including but not limited to: vases, picture frames, and your grandmother's dentures
Step 3: Engage the Pet: Hold the laser pointer at a 45-degree angle and move it in a zig-zag pattern across the floor, while simultaneously shouting 'Who's a good kitty?'
Step 4: Add a Twist: Toss in the can of tuna for an added layer of complexity and existential dread
Step 5: Observe and Learn: Study the intricacies of feline physics, including but not limited to: the trajectory of a thrown ball, the aerodynamics of a swooping cat, and the probability of getting scratched by a cat who's not in the mood
