A perpetual motion machine of the first kind produces work without the input of energy. It thus violates the first law of thermodynamics: the law of conservation of energy.

"I really like this dancing couple kinetic only problem was it wasn’t in a shipping box I had to peel off label I bought for my parents 65th Anniversary it is well made and looks great when you start it .

For the purpose of answering this question, I suggest that students should now propose potential mechanisms that explain what is seen and then work through the implications and plausibility of each mechanism. After this, groups of students could argue for or against some of the proposed mechanisms, a technique that reinforces concepts learned earlier in a physics course, but that also requires a deeper understanding of the concepts as opposed to learning by rote or memorization. It would obviously be desirable for students to have access to the toy shown in Ref.
Any device powered by changes in air pressure, such as some clocks (Cox's timepiece, Beverly Clock). The motion leeches energy from moving air which in turn gained its energy from being acted on.

Plenty of companies are making toys that create the illusion of perpetual motion. Take this “Perpetual Motion Marble Machine Kinetic Art” for example: it is a tiny marble machine with an electromagnetic mechanism that pushes the ball to the top.
The circuit takes the light from the solar cell, stores it and releases it in a pulse, making the gear wheel move, which eventually drops the marble down the spiral.
