8. Wizard’s Brew
For this activity that’s up next on our list of science activities for toddlers and preschoolers you will need a few things like baking soda, watercolors (you can also use food coloring), dish soap, vinegar, glitter, a glass jar, and a tray. The first thing you need to do is fill the jar with vinegar but only a half of it. Then add a little color and glitter, after which you can pour the dish soap and stir. When you put the jar on a tray, now add a little baking soda and stir again. This is when the foaming is about to begin and everything becomes interesting. You can continue adding baking soda and different colors if you want to make it more fun.
