Wacky Cake

1 1/2 c. flour

1/4 c. cocoa

1 c. white sugar

1t. baking soda

1/2 t. salt

1/3 c. salad oil

1t. vanilla

1t. vinegar

1 c. water

   Preheat oven to 350 degrees (F).  Mix dry ingredients into an ungreased 8"x8" pan.  Make 3 holes in the mixture.  In one hole, pour the vinegar; in the next hole, pour the oil; and in the last, pour the vanilla.  Pour water over the whole works and mix just until combined.  Bake for 30 minutes.  Cool and eat!   

This demonstrates when an alkali and an acid are mixed, causing a chemical reaction.  Vinegar and baking soda are leavening agents in this recipe.  They create gas bubbles that cause the cake to rise.

warning, once you get your kids started playing with vinegar and baking soda, they'll want to do all the old favorites, so get ready to turn 'em loose!: model volcanoes, plastic pop-bottle rockets,  (any other ideas?)

 Have fun! Get messy! Frugal Mama
