We made a few changes to our water wall
It is now a little more colorful and has some fun new aspects to it
I put the caps back on the bottles (after drilling a few holes in them). With the caps on the water flows in a slower and more direct current. Which made it also possible to put the ball pit balls in the bottles the kids can fill the bottle and watch the bottle float until all the water drains out.
Remember how I said I wanted a a water wheel. Well I started looking around for something I could use like a water wheel and I found the kids pinwheels we had set around the garden. Turns out they work fantastically as water wheels
