Our Vinegar & Baking Soda Experiments

The boys and I have been participating in some mini-science experiments involving vinegar and baking soda. The first experiment, eyedropper volcanoes, was such a hit, we've done it a few times. Then Jason decided to show them a bigger version, and as you can tell from the photo, it was also a big hit! I don't think the boys quite understand why this happens, but we sure have fun with it!  

 

Their faces crack me up!
