Here's yet another number cruncher for meteors. This would be a good calculator to run before a test drop, then compare the results! I love this idea. What fun. You'll notice, if you run the calculator that the bowling ball would make a bigger crater than Patrick would (just kidding). Maybe we could get a panel of material scientists together to do a little commentary. Just don't do anything for two weeks until I have free time and can come watch!! <A HREF="http://www.lpl.arizona.edu/tekton/crater.html">Click here: Crater</A> from the U of Arizona Tucson Bob St. Marie
