RA checked 27/01/11. It seems

RA checked 27/01/11. It seems sensible, but I don't understand the comment "the weights are covered with foam" as I don't see any mention of weights in the kit list or experiment description. Come to that, I don't see any mention of a "long bar" either... does anyone familiar with this experiment want to flesh out the description?
