I worked at the Academy of Natural Science in Philadelphia about 10
years ago and install the dig there. I'd have to check my files for the
formula, but I'm sure they have refined the mix since then. It's still
going after 10 years! You might want to try them...

Dear Colleagues-

We would like to experiment with a substrate of wax, sand, sawdust, and
petroleum jelly in our dinosaur dig, but don't know the correct
proportions of the ingredients for creating the mixture.  Do any of you
have a recipe you'd be willing to share?  We'd also appreciate any tips
on maintaining the substrate as well as tools for visitors to use in
their excavations.

Thanks for your help!

Lisa
