The first sprinkler that we tried out was a swirly-thingy that shot plastic balls out of it when you sent them down the swirly tube.
Since that one wasn't working, I decided to also put out the water spraying inflatable beach ball. I thought that surely they would like this one since they both like to hit around balls and play with them. And I could interact with this sprinkler a little bit more. That just wasn't the case.:(
I was able to lure Heffner in for treats. So he at least got some refreshing. Bess wasn't having any of it. I think I got her in just far enough for a few sprinkles to hit her head and then she was off to our porch couch. I did manage to take a little video of them playing in between me setting up the beach ball sprinkler. It was starting to cool off. Although, when your starting point is 110 degrees, cool is really relative!
My next toy to try out with them is the Slip 'N' Slide! I just happen to have a Star Wars one that I've been dying to get out. Unfortunately our lawn is pretty hard and lumpy, so I'm going to have to figure out how to work around that without bruising myself all up.
