I needed a quick activity to distract the girls after a fight broke out over princesses and castles (as most fights do), so I pulled up a DIY tornado in a jar from Pinterest. My original link didn't open up, so I googled it and found this recipe for it - we made our tornado pink, as all things should be:
1 Glass Jar
1 tsp dish soap
1 tsp vinegar
food coloring (optional)
Fill jar 3/4 with water. Add dish soap and then vinegar. Add food coloring. Stir rapidly with butter knife, and then pull out - your tornado should appear!
