I recommend starting with an idea of what you want to do. PVC is fairly inexpensive, and easy to work with. You'll want to make sure you have everything ready. First cut PVC pip to ideal size (my husband did this while i was getting the girls ready). Next drill holes into the top PVC piece. Don't add too many or the water pressure may not make it shoot out.
I was super impressed with how it came out. It is a lot of fun for the kids (at I admit, grown ups ;)
