Title: K'nex Screamin Roller Coaster
Review: A fantastic project! My 6 year-old son and I built this in 4 days during Christmas vacation. After a minor adjustment at the top of the hill we had it working perfectly with absolutely no problems whatsoever. We don't know whether it was more fun building it or watching it perform flawlessly again-and-again!I highly recommend this, but be prepared to do some work to get it put together!
