Materials:

• 1 cup of used coffee grounds
• 1/2 cup of cold coffee
• 1 cup of flour
• 1/2 cup of salt
• Waxed paper
• Mixing bowl
• Some small objects to make impressions in the dough such as shells
• Empty can or a butter knife
• Toothpicks, optional
• String to hang fossil, optional

Directions:

1. Stir together the coffee grounds, cold coffee, flour, and salt until well mixed.
2. Knead the dough together and then flatten it out onto the waxed paper.
3. Use the can to cut out circles of the dough or use the dull knife to cut slabs large enough to fit your "fossil" objects.
4. Press your objects firmly into the dough. When you take the object out, you have your "fossil". If you want to hang the fossil, poke holes into the edge to hold the string.
5. Let the fossil dry overnight and then hang it if you wish.
