In case you weren't sure if dolphins were geniuses, I have a video for you. This is a "game" they play underwater! It's AMAZING.
Contrary to dolphins, humans are not so genius most of the time. We just want to have a good time without using our noggins.
As much fun as this looks, and how bad I want to try it, the end result isn't so appealing.
And this might be why they tell you not to dive in "shallow waters."
And that is the difference between genius and moron, I guess. And between animals and humans. They're awfully clever, and don't even have technology to use all the time! [Well, you know what I mean.]
On a real note though, the tubing in the flood looks like a lot of fun. And I want to try it. Minus the pole.
