Simulated Meteor impact in slow motion

We where contacted by an educator at the UT McDonald Observatory that wanted to use a clip in a lecture to demonstrate meteor impacts so we also added this clip too for them.We dropped a glass ball from 12 feet and recorded the impact @ 5000 FPS. This is their description: This slow motion impact video is a good model for how craters are formed on the surface of the moon. When we observe real lunar craters, we see all the below described impact features, but there are a few limitations in this model. This is ok, because you've made a scientific model - all scientific models have limitations, and when we identify those limitations, we have an even better understanding of what is being represented. The lunar surface is represented by the flour, and darker cocoa on the surface. The white flour and dark cocoa help to distinguish between material at the surface, and displaced material below the surface. The impactor is represented by a glass sphere. At impact a great deal of material is displaced forming interior "crater walls". After impact, an uplifted "crater rim" is seen surrounding the edge of the crater (particularly in the right hand movie). The displaced material from below the surface spreads outward from the impact site. On the moon, we see prominent crater walls, rims and "ejecta", the sub-surface material ejected 1000's of kilometers from the site. Ejected material form "rays" which are bright streaks extending away from the crater. The limitations of this model ...
