It's been around 113F here lately so if we're playing outside you can bet it has something to do with water. We're lucky that we have a dry (except during monsoon season) heat so water on our skin evaporates and cools us off quickly!
I found some fun DIY Sprinkler ideas because why buy a cheapy plastic one when you can just make your own. Or better yet - have your kids make it!
