Finally, kids have something that might actually be more fun than riding a roller coaster. With Knex Roller Coaster Sets, you can actually build a fully functioning roller coaster that teaches children about acceleration and gravity in a fun and lighthearted way. 

The Knex Rippin' Rocket Roller Coaster actually features a five-foot peak. Just like its full-sized counterparts, the Knex Roller Coaster offers thrills and exciting, gravity-defying fun. This Knex set actually won three major toy awards, including Family Fun Magazine's Best Toy of the Year Award and the Parent's Choice Award. 

With the Knex Rippin' Rocket Roller Coaster you can construct two separate and exciting roller coasters - the original Rippin' Rocket coaster and the Turbo Storm Roller Coaster. Both models make use of the turbo booster that helps speed the rocket cars along the rails. Over 25 feet of track is included in the set and adds to the construction excitement! 

The completed Rippin' Rocket model is six and a half feet long when fully constructed. This fast moving coaster is recommended for children ages 10 and above and comes with 1,058 pieces. Step-by-step instructions are included, and the Rippin' Rocket requires six C batteries to blast off.
