Today for science Jonathan and Madi made "foaming monsters". First they decorated plastic bottles (Madi made a spider and Jonathan made a tree) then you fill bottle half way with vinegar, a squirt of dish soap, and food coloring. Next you put a teaspoon of baking soda in a tissue, wrap it up and drop it into the bottle. The vinegar and baking soda make carbon dioxide which reacts will the soap to make foam. The foam then pours out of the "mouth" of the bottle.
Yes, now Jonathan and Madi are the ones still in yesterday's clothes, when you homeschool you can do that!
