Guess the Physics: Grug's Caveman Experiments

12 real physics experiments. One caveman. Grug guesses every one, and so do you. Pick A, B, C or D before the timer hits zero, keep score, and post your score in the comments. Grug got 5 out of 12. Can you beat him? Every experiment is a real rigid-body physics simulation built and run in Blender. The slow-motion replays come from the same simulations. No AI-generated video. What's inside: momentum, why close isn't enough, levers, glass and energy, the bell curve (Galton board), why cuts multiply, falling energy, the harmonic brick-stacking trick, toppling towers, bouncing pebbles, granular "liquids", and domino amplification. Want to make sims like these? The Grug Physics Kit for Blender has the scenes, physics toolkit, ASMR sound and render pipeline: https://cavemanbrain.gumroad.com/l/gr...
