Phil, the movie to the right resembles what your group should do, except instead of pendulums you will use three masses. The center one has twice the mass and twice as many pendulums (two pendulums in parallel double the spring constant, and this makes each pendulum have the same frequency.

Try reversing the strings and the springs
Look at the image to the far right of this page. The way to do the demo is to put the center one into motion, and then wait for the center one to stop while the two outer springs get all the energy. Then, the energy goes back to the center mass while the outer masses are motionless. Also, the springs should be vertical while the strings are horizontal. Otherwise, everything looks good.--Guy vandegrift (discuss • contribs) 01:51, 1 December 2016 (UTC)
