Backyard Water Slides Dangerous

Fun for teenagers to do in the summer ..?

Schools almost over and I well buy some things to put in the backyard to go a good time. I wanted to get a form of n slides, but I realized that it is dangerous for teens to use those. I can not make cause our backyard pool just grass and work too. Are your anythings (a slip n slide, water guns, etc.) is available that teens can use for fun. Any idea? I want something like a slip n slide or slip n slide that teens can safely use to be made. Also, do not want anything too expensive.

a couple of years ago my sister and her friends went out on this sweet n 'slide, which was over 100 feet long and better (and cheaper), then one can buy in a shop … you just get this thing long plastic (not sure what it was) and then put a hose on the end and it worked very well, so you could do that … and is the only way to get hurt if your being silly, or go sliding off the end and fell like a rock or jam with your finger, or you can play paintball, which is awesome !…. but I've never seen a child playing, I think your girl, but I'm not saying I can not play
