ISEN-ASTC-L is a service of the Association of Science-Technology Centers
Incorporated, a worldwide network of science museums and related institutions.

When I worked at the Natural History Museum of Los Angeles we developed  
an exhibit called the Tiniest Giants: Discovering Dinosaur Eggs, where  
we used ground up recycled tire rubber as a substitute for sand in our  
dig pit.  It seemed to work well, without all the mess that sand  
creates.
