We have had a good day today.  Busy as always.  Here is a picture of Abigail posing with her yeast experiment. There are also pictures of Abigail and Ethan punching down the bread dough, because we also made bread.  She discovered that the yeast mixed with plain warm water will not bubble, but the yeast mixed with warm water and sugar makes foam and bubbles.  I explained that the sugar is food for the yeast and after the yeast eats it, they give off gas.  I'm not sure if she will remember, but it was fun.
