13 large marshmallows 1 maraschino cherry   (remove stem) 1 tablespoon butter 2 cups crispy rice cereal 1/2 cup creamy peanut butter 8 chocolate cookies pot spoon butter knife plate sandwich bag
	To make the inner and outer cores: Use a butter knife to carve out the middle of one large marshmallow. Insert cherry into the center of the marshmallow (the cherry will be Earth’s inner core, and the marshmallow will be the outer core). Put aside. To make the mantle: Find a grown-up to help you. On the stove, melt the butter. Stir in the rest of the marshmallows until melted. Remove from heat and stir in cereal. Cool for 5 minutes. Wet your hands with water. Then roll the cereal mixture into a ball around the core. To make the crust: Use a butter knife and spread a thin layer of peanut butter all over the mantle. Then put cookies inside a sandwich bag, close the bag, and crush the cookies into crumbs. Pour cookie crumbs onto a plate. Roll your Earth in the cookie crumbs until all the peanut butter is covered. Slice your Earth in half and admire the layers of inner core, outer core, mantle, and crust.
