Mad Science Camp: K’NEX Roller Coaster

I bought two K’NEX Roller Coaster kits (and here) from Good Will.  (I paid about $50 for both kits with shipping.). Paul and my husband, Rob, are building the roller coaster in the basement.  I am not sure this would be good for camp.  Our Co-op has a Lego Club.  I think the Roller Coaster Kit might be better as part of a K’NEX club.  But, if you have a group of less impulsive kids, you might have the roller coaster kit at a station on the side for teens.  Kids could work on the kit if they finish a project early, over the course of a week of Camp.  Here are a few pictures.  Progress is slow.
