Build a fish that swims in the air without any manual control?
My first post.
While walking by the toy store, I saw that they had a giant dolphin(filled with air) that was swimming around in air just above the head.....
so funny..a big fish swimming freely..giving you the impression that you are under water..
I could not even see if someone was controlling the motion...seemed to me that its 'altitude' and 'path' was kind of pre set and it would continue to hover until its battery ran out or something.
Is there a way to build this? like fill up a ballon (shaped like dolphin) with air, and program it with some kind of bult in controller that makes it hover...?
