Q&A for How to Make a Homemade Water Slide

Yes, you can. Just be careful as it can be extra slippery.

Connect trash bags together (possibly with duct tape underneath) to make a tarp and pile up dirt to make your own hill.

It sounds like it would be dangerous. You would likely be going too fast and would overshoot the kiddie pool. It is best not to do that.

You could try finding a grassy hill at your local park and putting a wide layer of plastic down it. But if you meant a water slide into a pool, you can buy them really cheap at a Target or Kmart. Or, alternatively, you could borrow someone's metal kiddy slide and run a tap over it.
