The set is geared for ages 7 and up but my 6 year old had no problem following the directions and manipulating the little pieces. There were 10 different building suggestions in the guide and instructions on how to find more on the K'nex web site which is amazing. There are areas for parents and educators, a K'nex club, product guides and of course an online shop-K'nex Direct. K'nex gives back 10% of all sales on K'nex Direct to the Children's hospital of Philadelphia and there is free shipping on all orders over $100.
This a replica of the Ferris Wheel at Navy Pier in Chicago, it is in one of the gift shops, trust me when I say this pictures DOES not do it justice, it was quite impressive and was actually spinning!
