🏖️ Sandbox Impact Lab: Ball-Drop Craters, Energy Scaling and Ejecta Rays

Drop steel, glass, wood or rubber balls into a bed of sand on Earth, Mars or the Moon: measure the crater and compare it with the energy-scaling law, watch the ejecta fly ballistically, and fire shallow shots to see butterfly-shaped ejecta.
