  A pleasant illusion can arouse your imagination to flow and not to freeze...

There`s a similar thing on youtube, but the person built it using sledge hammers! :)

      Hi !
I suppose it's taking about "Thor's hammers" .

You can find it at:   http://www.youtube.com/watch?v=vh2a4a6JPM8

The real performance can be to play a single hammer (with a variable handle),in the manner of higher up  "two swinging sticks".

    All the best! / Alex

.....as you can see up there (The swinging sticks/big size) ,can be a quick insight,mental "entry" and an easy allusion (an indirect,or quite direct reference...as you like) for a possible  self moving lever (a two sticks type game) due to gravity fall-inertia storage interplay...

.....can jump from a false idea or conception,to a common elementary real fact,if you take a short look at :   http://www.youtube.com/watch?v=EcmMvFj5b_0 (http://www.youtube.com/watch?v=EcmMvFj5b_0)

    As an abstraction ,thinking apart from the material objects ,we have a fulcrum ,a straight line/bar ,and a mass moving to and fro at one end of the bar.

    If we replace the performance of the acrobat with "something"...can we have a "new game"(self-motion,due to gravity and inertia)?!

    Remind that sometimes,the wonder is the seed of our science...

.....can "jump" so easy,from illusion to reality,if we replace the performance of the acrobat at:   http://www.youtube.com/watch?v=j6pTgz9hkf8&feature=related (http://www.youtube.com/watch?v=j6pTgz9hkf8&feature=related)   with a "something",as I supposed up there...

This "something"  can be  a simple hinge,free to rotate no more than 180*...if you play gravity fall and inertia "spring"/in-out storage...

    All the best! / Alex

 
.....with a slow motion,this time at:   www.youtube.com/watch?v=PjfejVNRqQg

     Can this strange illusion help us,to test a possible self-motion..due to gravity and inertia,in the most simple mode (and SHAPE!!!...)!?

     My opinion:try to limit the rotation of the small stick...that's all !

        All the Best! / Alex 

.....sometimes is a very slight , gradual  or subtle difference.


Let's take a look at : www.squidoo.com/the-swinging-sticks-kinetic-energy-sculpture (http://www.squidoo.com/the-swinging-sticks-kinetic-energy-sculpture)


Their challenge related to the shape is : this is the "outside" of a perpetuum mobile device.


Their secrecy about the working principle is :the "inside" has "hidden" spare parts (coil , magnets ,electric battery ).


If we keep on their challenge about the  "outside" (shape ) , can we play continuous motion , without the "inside" (hidden spare parts...) ?

Seems like a type of chaotic pendulum.

      Hi  !
Really , it's a chaotic pendulum , due to an interplay  of gravity unbalance and  a magnetic "boosts" process (magnets in the sticks vs. coil and electric battery in the basement).


If we add a rotation restriction for the small stick ("no more than 360*") , I suppose , we can obtain a regular spinning (so , not a chaotic one...) ...maybe a more accurate "mimic" motion of the "perpetuum motion "(this is their "challenge"!).

It can be the first step TO a "clean"  continuous  mechanical  motion , due to gravity unbalance and rotational inertia...
