Take a 2 liter soda bottle, poke holes in it. Attach to a garden hose. Toss over a tree branch and let hang for a kids water sprinkler. You can loop it over a tree branch and let kids bat it around for more watery fun!
DIY easy bubble blower - made with empty water bottle! The kids loved it! There was a "fight" over a larger water bottle until the kids discovered you can make longer bubble "tails" with a smaller bottle (requires less air to blow).
