Perpetual Motion Object

There are probably a number of sites where you can buy a fake perpetual motion device on the worldwide web. All of them will be a waste of your money. There is no such thing as a perpetual motion device. Simply put, its' against the law. The Law of Conservation of Energy, that is. This law states that energy may neither be created nor destroyed. Therefore the sum of all the energies in the system is a constant. What this means in the context of a perpetual motion device is that, with all the physical constants such as friction, etc. any energy supplied to a system will eventually be used up. Since the system cannot produce more energy than it begins with, it will eventually stop doing whatever it is doing (the motion part). People have been trying to make a perpetual motion device since the beginning of recorded history and a great number of them have been sold, but they are all rip-offs. Don't waste your money.
