This week we are having a science camp here at home because that is this week's theme at preschool camp (and I couldn't send them both for another week of camp). This morning we did a couple of baking soda and vinegar experiments. The pans on the left I had put a layer of baking soda in and the the kids used eye droppers to drip food colored vinegar on it. That kept Freddy entertained for a good 20 minutes and Lucy happy for twice as long. 

On the right is the pan of sponge candy I made while the kids watched (way too hot for them to help with). It was exciting to watch the pan of sugar grow into a huge foamy pile. All three of us can't wait for it to cool so we can taste it!
