Ok, now we we're all acquainted with Air Ray, right? Well, meet it's baby watery cousin Aqua Ray by Festo! Mimicking the movement of its larger real life counterpart (the Manta Ray) the Aqua Ray has the ability to realistically swim, dive, and turn like the real thing. From the video you can gauge the size of the Aqua Ray when you see the diver next to it. Tiny and adorable! I want to buy a carton full of these and put them in an Olympic sized pool and swim in it.
