Here's a fun little video with visual instructions for some very beautiful, interesting science experiments. Most of these experiments involve color, so they are a delight to look at! With them, you can explore topics such as the density of liquids, primary and secondary colors, and chemical reactions. Here at my house, we have done a few of these experiments. They are a lot of fun! Supplies include generally easy-to-find items such as food coloring, vegetable oil, and a few other items.
