We got a great science book at the library recently and have had a lot of fun trying out some of the experiments in it. We made some baking soda crystals last week, the formations on them were spectacular, it was fun to see them grow more and more intricate, until I got sick of it taking up counter space. Then it was time for a picture and dump them in the sink.
Here's how to do it:
Take two mason jars, fill them each with warm water. Stir in baking soda in each jar until it will no longer dissolve. Take a piece of yarn and tie a paper clip to each end. Dip the string in one of the jars to get it completely wet. Place each end of the string in a jar and wait a few days for your crystals to start forming.
We are going to do some research on stalactites and stalagmites to see how they form.
