The previous Hip Hop Dancer on Fantastic Contraption was a failure. However, I did not give up making more random stuff.

At last, I've invented this: http://FantasticContraption.com/?designId=2920180

With only 2 clockwise wheels, 2 wooden rods to join the object together, 6 water sticks to increase the mass.
The 2 wooden rods and 6 water sticks are too heavy for 2 wheels to move them, however, the wheel is still spinning, at the same time, generates potential energy. When the potential energy reaches a level, it automatically converts to kinetic energy and it gives an amazing spring-like effect. You must watch it. Here I give you again: http://FantasticContraption.com/?designId=2920180

I call this transportation "Butterfly", it has 2 wings, a head, and some patterns, most importantly, it flies.
