I suggest "dry"- assembling a few components ahead. PROS: This is a heavy duty set. I like Ugears, Woodtrick, etc - but those super-light weight wood makes them delicate. Also, unlike those other brands, you don't have to lubricate any of the gears." wooden marble run kinetic art perpetual motion device the great wooden toys for boys
These types of machines may involve two chambers with pistons, and a mechanism to squeeze the air out of the top chamber into the bottom one, which then becomes buoyant and floats to the top. The squeezing mechanism in these designs would not be able to do enough work to move the air down, or would leave no excess work available to be extracted. Patents[edit]

Oh ye seekers after perpetual motion, how many vain chimeras have you pursued? Go and take your place with the alchemists.
A more thorough analysis showed that when a physical ratchet was considered at this molecular scale, Brownian motion would also affect the ratchet and cause it to randomly fail resulting in no net gain. Thus, the device would not violate the laws of thermodynamics.
1 There have historically been many purported perpetual motion machines.2,3 A close analysis of the machine invariably finds either that there is some assumption that violates the laws of thermodynamics or that there is some input from an external energy source, which means that the system is not isolated.4,5 In this article, we will consider an amusing example of such a machine, in which a ball starts on a platform, falls through a hole, and slides down a track formed from two side-by-side stainless steel rods.6 I explain how the machine can be used in class to illustrate physical principles, outline the possible mechanisms, and end with an explanation of the correct mechanism.
