Making Fossils (DRY MIX)



Manufacturer Contact Info


 
"Dig your own fossil"
These kits have been around for ages. It’s always fun to chip away at dirt/clay/rock to find some sort of treasure inside. The trouble with many of these kits, beyond the lame toy at the end, is that they are short-lived. Dig for ten minutes and you’re done. So, make your own bigger and better, of course!

You’ll need:
Dig1Plaster of paris An equal amount of dirt, rock, and sand (for realism, naturally)
A small, shoebox sized plastic storage bin, or foil baking pan.
Plastic dinosaurs, shells, or other diggable treasures
Water
A bucket for mixing
A large stick and garden trowel for stirring
A nice day

Material to water ratio is 2:1. Mix your plaster and dirt together in the bucket and add water a little at a time. Mix with your stick and keep mixing until you get good creamy mud. Pour in a layer of mixture into your mold. Add your "fossils," add a layer of mixture. Repeat in layers until you fill your mold.
