stuck on 52

stuck on 52 help please its driving me crazy and i am sure it is right in front of me but i dont see it!

Attach a rope from ceiling hook to weight, then place magnet like upside down U under weight and over switch to protect switch and leaving enough room for ball to go over magnet. Attach one electric cable from middle distributor to right distributor. Then one from right distributor to middle light bulb, lastly one from left distributor to left light bulb. Good Luck

got it thanks!
