Animal Track Fossils

Materials needed: 1 cup flour, 1/2 cup salt, 1 tbsp cooking oil, 1 tbsp cream of tartare, 1 cup boiling water, animal toys with different feet.
Step 1: Making the dough. Combine flour, salt, cooking oil, cream of tartare in a large bowl. Add in the cup of boiling water and slowly mix it. It is really important to make sure the water is boiling. I tried with just hot water and the play dough had a completely different consistency. Once it cools a bit, have an adult clump the mixture together until it is cool enough for kids to handle. Knead until desired consistency is reached. Feel free to add some sand to give it a cool texture when it's finished.
