champions_sharron Impact cratering videos:

      High cal ones:
      1. Simulated Asteroid Strike | 0:52: On sand and ice. Looks good. Short enough for the classroom.
      2. Impact Movie: Copper sphere in fine particles. There is a full caption. Short enough for the classroom.
      3. Slow motion : "Meteor Crater" | 0:18: Airsolf pellet shot into sugar. But only 50 m/s, which is way too slow for a real simulation of impact cratering. Short enough for the classroom.
      Low cal ones:
      1. Nuclear Bomb Test Subsidence Crater Formation | 0:08 : This is from underground nuclear bomb test. Not much like impact cratering, but impressive. Short enough for the classroom.
