Outdoor water play/ Exploring with water.
My set up may not be the prettiest, but boy did we have fun.
I used tape and taped our watering system to our glass sliding door. If you have a 1 gallon water jug cut that in half, and use that as part of your water system.
I put this together using a few play eggs. We made sure to tilt them so that when water is poured into one it can easily make it's way to the next egg I used a few items from our kitchen. Using the other half of your jug to collect the water, or you can use a bucket. My daughter loved pouring water and watching it make it's way down.
This is very hands on, and did I mention fun for the little ones!
