Volcano

Ingredients

 * Clay -- modeling
 * 1 tsp baking soda
 * food coloring -- red
 * 1 tsp vinegar

Directions
1 My favorite kiddy project is the classic baking soda and vinegar volcano. 2 Make a volcano out of play doh or modeling clay. 3 In the crater put baking soda and perhaps a little red food coloring. 4 To display, pour vinegar in it and watch it erupt!
