Just add water and a dozen squealing 8-year-old kids and you're there.
I didn't get the "no standing" rule... You kind of have to stand up in order to walk up the center of the thing in order to slide down. The silly string rule was not violated. Winds were low. All went well.
I was kind of concerned about "MADE IN CHINA" on the label but I figured they probably wouldn't be chewing on it so it should be OK.
