Here is a super simple activity we did this week that was loads of fun. Simply put some dish soap into a puddle. It was raining on and off which it typically does in Spring but the kids really wanted to play outside. First it was some bubbles my youngest wanted to pour into the puddle so in it went. Then they decided to try dish soap. Add in a broom or some tree branches and they mixed up a soapy puddle. No joke they played with the soapy puddle for about an hour and only stopped because it was dinner time.
