It is a neat little science project site, and I found this project the most interesting (except for the non-elecricity requiring radio) on their site. How it tells you it works(shortened): You take a ruler and place 4 cubed magnets and place 2 metal marbles in between each and only 1 at the ends. Then you let go of the first one and it rolls toward the magnet w/ a kinetic energy of 1. Then the KE is transfered through the magnet to the second ball with a KE of 1, and then that ball hits the 3rd one with a KE of 1. By the time they hit the second magnet they have a kinetic energy of 2 and it keeps on building up untill the last one is hit and the marble goes flying across the room from trmendous amounts of KE.

What I want to know is (in more detail) how the KE is carried and what the resulting amount of kinetic energy is by the time it hits the last marble. Please help me work out the math. I think I understand how when the 2nd ball hits the third with a kinetic energy of 1 it transfers it to the 3rd ball. But do they both then move toward the 2nd magnet with the power of 2 KE since their sum of their KE equals two? Or is that no correct? Would it be 1 instead? And if so then how does it build up the KE? Help please.
